START HERE — THE SHORT VERSION
It's common. Recent population data show foot osteoarthritis is as prevalent as knee osteoarthritis, with rates rising with age.[1] Symptomatic radiographic foot arthritis affects about 1 in 6 adults over 50 — a population prevalence of 16.7% — and three-quarters of those people report disabling foot symptoms.[2]
Location matters most. By joint, population prevalence of symptomatic radiographic arthritis: big toe joint 7.8%, second cuneometatarsal 6.8%, talonavicular 5.8%, navicular-first cuneiform 5.2%, first cuneometatarsal 3.9%.[2]
Weight is the most modifiable factor. Adults with obesity had more than twice the odds of radiographic foot arthritis and more than five times the odds of symptomatic foot arthritis.[3] In longitudinal follow-up, higher BMI predicted new arthritis and worse scores on every Foot and Ankle Outcome Score subscale.[4]
Progression on X-ray ≠ progression in pain. Over roughly 3 years, 55% of feet with existing arthritis progressed radiographically — but only 16% of those developed symptoms.[4]
Surgery works when it's needed, and no single operation wins. At 10+ years, total ankle replacement and ankle fusion showed similar functional outcomes.[5]
└─────────────────────────────────────┘
Let me tell you the moment that repeats itself in my clinics in McKinney and Flower Mound almost every week. A patient hands me an X-ray report and says, "It says severe arthritis. How long before I can't walk?"
And I get to give them good news: that film does not predict your future. We have hard data on this now. Most feet that look worse on X-ray over time don't feel worse.[4] What I care about is what you can't do that you want to do — and how much of that we can get back.
Here's everything, organized the way I actually work through it.
───────────────────────────────────────
PART 1: WHAT'S ACTUALLY HAPPENING IN THE JOINT
Cartilage is the slick white surface capping the ends of bones. It has no nerves. Bone underneath it does.
As cartilage thins, load transfers to the subchondral bone, and that's where pain originates. The body responds by laying down extra bone at the joint edges — osteophytes, or spurs. On imaging, arthritis is graded by exactly these two findings: osteophytes and joint space narrowing, each scored 0–3 using validated atlases.[4]
That second feature explains a complaint patients bring up before pain: the bump. A hard knot on top of the midfoot, or on top of the big toe joint, is a spur. It is frequently the reason shoes become intolerable long before the joint itself becomes the problem.
Three different diseases wear the same name
Type | Driver | Foot pattern | Reference |
Post-traumatic OA | Prior fracture, sprains, instability | Usually one joint; dominant cause in the ankle | |
Primary OA | Age, mechanics, load, body weight | Big toe and midfoot; obesity a strong factor | |
Crystal / inflammatory | Gout, rheumatoid, spondyloarthritis | Multiple joints, both feet, prolonged morning stiffness |
A finding worth knowing about gout. In the Johnston County longitudinal cohort, a history of gout was associated with incidence or progression of foot radiographic arthritis (aOR 2.75; 95% CI 1.24–6.07).[4] If you've had gout attacks in the foot, controlling it is part of protecting the joints — not a separate issue.
And on sex differences: women were substantially more likely to develop new foot arthritis (aOR 4.10; 95% CI 1.22–13.8), and prevalence was higher in women, rose with age, and was higher in lower socioeconomic groups at nearly every joint.[4][2]
───────────────────────────────────────
PART 2: THE FOUR REGIONS — AND HOW EACH ONE FEELS
REGION 1 — THE BIG TOE JOINT (Hallux Rigidus)
The most common arthritic condition in the entire foot. Population prevalence of symptomatic radiographic arthritis at the first MTP joint:[12] 7.8%.[2]
What patients describe:
- Pain on top of the big toe joint, not the side
- Worse with push-off — stairs, hills, sprinting, getting out of a chair
- A dorsal bump that rubs in dress shoes and cleats
- Progressive loss of the ability to bend the toe upward
The exam finding that clinches it: loss of dorsiflexion. Preoperatively, most patients in a 153-patient surgical series lacked dorsiflexion at the first MTP joint entirely.[13]
The most common misconception I correct: this is not a bunion. A bunion angles the toe sideways; hallux rigidus stiffens it upward. Different problem, different surgery. Bunions (Hallux Valgus): Causes, Symptoms, Treatment and Surgery
One myth the literature has actually killed: you may have been told your first metatarsal is "too elevated" and that's why the toe is stiff. In Coughlin's long-term series, there was no association between hallux rigidus and hypermobility of the first ray, functional hallux limitus, or metatarsus primus elevatus — and dorsiflexion stress radiographs corrected the apparent elevation to nearly zero.[14]
REGION 2 — THE MIDFOOT
The second cuneometatarsal joint (6.8%) and first cuneometatarsal joint (3.9%) are the usual culprits.[2]
What patients describe:
- Deep ache across the top of the arch, worse the longer they're on their feet
- A bony ridge on the top of the foot that hurts under laces
- Peak symptoms at the end of a workday or a day at the ballpark
The history I always ask about: a prior midfoot injury, even one that seemed minor. Midfoot arthritis is a recognized long-term consequence of a Lisfranc injury, which is why these are treated so aggressively up front.
REGION 3 — THE HINDFOOT (Talonavicular and Subtalar)
Symptomatic radiographic arthritis at the talonavicular joint: 5.8%; navicular-first cuneiform: 5.2%.[2]
What patients describe:
- Pain below and in front of the ankle, not in the ankle itself
- Dramatically worse on grass, gravel, trails, and uneven ground — because these joints do the side-to-side accommodating
- The tell: "I'm fine on the treadmill and miserable on a hike"
Where it comes from: an old calcaneus fracture, a longstanding collapsed arch from posterior tibial tendon failure, or an untreated tarsal coalition. Posterior Tibial Tendon Dysfunction (PTTD)
REGION 4 — THE ANKLE (Tibiotalar)
The ankle is affected less often than the big toe or midfoot — but when it is, it is the most limiting.[1]
What patients describe:
- Deep pain in the front of the ankle, stiffness, swelling after activity
- Loss of upward flex, so stairs, ramps, and squatting become hard
- A history that almost always includes an injury
Where it comes from — and each has its own guide:

PART 3: GETTING THE DIAGNOSIS RIGHT
Here's an honest admission about my field: there are no accepted clinical diagnostic criteria for foot or ankle osteoarthritis, so imaging remains common. That means the history and physical exam carry real weight, and the imaging has to be done correctly.[1]
What I'm doing in the exam room
1. Isolating the joint. I press one joint at a time, and I ask you to tell me when I hit it. Big toe, first CMJ, second CMJ, talonavicular, subtalar, ankle — each has a distinct tender point, and the tender point usually is the diagnosis.
2. Measuring motion. Big toe dorsiflexion in degrees. Ankle dorsiflexion. Whether the hindfoot inverts and everts or is locked.
3. Assessing alignment standing. Heel varus or valgus, arch height, forefoot position. Alignment determines whether a joint-preserving operation is even on the table.
4. Watching you walk. Down the hall, both directions. Gait reveals what tests miss.
5. Screening for the impostors. Tendon disease, stress fracture, and nerve pain all mimic arthritis:
Imaging: the standard is standing, and it's two views
The major population studies of foot arthritis all used weight-bearing dorsoplantar and lateral radiographs of both feet, graded with a validated atlas.[4][2]
┌─────────────────────────────────────┐
Why standing matters: a non-weight-bearing film relaxes the foot and hides the collapse and joint narrowing that produce your symptoms. If your foot X-ray was read as normal but the pain persists, ask whether you were standing and whether both views were taken.
└─────────────────────────────────────┘
When I go beyond X-ray
- Weight-bearing CT — the best look at subtle midfoot and subtalar joint space and at fracture malunion. This is the study that most often changes my surgical plan.
- MRI — for cartilage lesions, bone marrow edema, and coexisting tendon or ligament disease. The same modality logic is spelled out here: How Lisfranc Injuries Are Diagnosed: X-ray vs. CT vs. MRI
- Diagnostic numbing injection — when three neighboring joints all look arthritic, numbing one tells me which is generating pain. In my view this is one of the most valuable tests in foot and ankle surgery, and it prevents fusing joints that didn't need it.
- Labs — when the pattern is inflammatory, or when gout is in the history, given its association with arthritis incidence and progression.[4]
───────────────────────────────────────
PART 4: NONOPERATIVE TREATMENT — WHERE MOST PATIENTS STAY
A candid framing: foot and ankle arthritis has been neglected by clinical researchers, and there are very few trials of non-surgical treatment, so most recommendations are extrapolated from knee and hip research.[1] For the big toe specifically, non-surgical management is recognized as first-line, but there are no widely accepted treatment pathways.[15]
That's not a reason for nihilism. It's a reason for honesty about confidence levels.
STEP 1 — Education, exercise, weight management
Guidelines recommend education, exercise, and weight loss in the first instance.[1] Across osteoarthritis, non-pharmacological measures — education and self-management, exercise, weight loss if overweight, and walking aids — are widely recommended as first-line treatment.[11]
Exercise: particularly helpful for decreasing pain and improving joint motion, with high-quality evidence and effect sizes of 0.4–0.5 in hip and knee OA. Strengthening plus general aerobic work is now considered a key element of osteoarthritis management; the real challenge is long-term adherence.[11]
Weight: this is where the foot-specific data are strongest. Obesity carried >2× the odds of radiographic foot arthritis and >5× the odds of symptomatic foot arthritis.[3] BMI predicted incident arthritis (aOR 1.60 per unit; 95% CI 1.31–1.97) and worse function across all FAOS subscales.[4] And there is a clear dose-response relationship between amount of weight lost and improvement in pain and function, with diet plus exercise outperforming either alone.[11]
Education: two sentences from the osteoarthritis consensus literature that change how patients feel walking out of my office — osteoarthritis is not an inevitable part of getting older, and joint damage on an X-ray does not indicate how much your osteoarthritis will affect you.[11]
STEP 2 — Mechanical offloading (the highest-yield move in the foot)
For ankle arthritis, offloading the joint by brace, cane, rocker sole, or insert is commonly used in clinical practice to reduce pain, though the Cochrane review is explicit that supporting evidence is lacking.[16] For the big toe, recommended options include shoe-stiffening inserts, accommodative insoles, functional foot orthoses, stiff-soled footwear, and rocker-sole footwear, along with stretching, strengthening, and gait retraining.[15]
In practice, this is where the most reliable relief comes from, because the foot is uniquely fixable with mechanics:
Problem | What I use | Why it works |
Big toe arthritis | Carbon fiber footplate or stiff-soled shoe; rocker sole | Stops the painful joint from bending at all[10] |
Midfoot arthritis | Custom orthotic with arch support; stiff shank | Reduces motion and load across the arch[10] |
Hindfoot arthritis | Cushioned, supportive shoe; UCBL or Arizona brace | Limits side-to-side accommodation on uneven ground[10] |
Ankle arthritis | Lace-up or Arizona-type brace; rocker sole; cane | Offloads and stabilizes the tibiotalar joint[10] |
Activity substitution counts as treatment. Cycling, swimming, elliptical, and rowing maintain fitness without impact. This isn't quitting — it's changing currency.
STEP 3 — Medication, in order
The stepwise sequence from the foot and ankle literature: topical NSAIDs or capsaicin as an adjunct → acetaminophen → oral NSAID or COX-2 inhibitor if symptomatic relief remains inadequate.[1]
┌─────────────────────────────────────┐
Safety, not fine print: adverse events and comorbidities are common in older adults, and older patients should be closely monitored on NSAIDs.[1]
Topical NSAIDs are underused in the foot. These joints sit just under the skin, the drug reaches them, and systemic exposure is far lower than with pills.
Note also that there are increasing concerns regarding the effectiveness and safety of acetaminophen for osteoarthritis.[15]
└─────────────────────────────────────┘
Glucosamine and chondroitin: benefit for pain reduction in general osteoarthritis has not been shown.[16]
STEP 4 — Injections, described honestly
- Corticosteroid: widely used, helpful for a flare or a specific event, and diagnostically valuable. Listed among recommended pharmacological options for the big toe.[15]
- Hyaluronic acid: there is some evidence to suggest it may be effective in the short term for ankle OA. Note that the 2026 AAOS ankle guideline does not support hyaluronic acid used alone — a genuine disagreement I lay out for patients rather than resolving for them. Ankle Arthritis Treatment in DFW: What the 2026 AAOS Guidelines Mean for You[1]
- PRP and stem cells: the evidence base does not currently support routine use in foot and ankle arthritis. Given the out-of-pocket cost, I'd rather patients spend first on offloading, therapy, and weight management, which are better supported and cheaper. The Real Science Behind Peptides and Healing Orthopedic Injuries
Where all this leaves us: with the lack of research on foot and ankle arthritis treatments, robust clinical trials are urgently needed.[1] Anyone claiming certainty here is overselling.
───────────────────────────────────────
PART 5: SURGERY FOR THE BIG TOE — THE MOST COMMON OPERATION I DO FOR FOOT ARTHRITIS
Surgical options include cheilectomy, Moberg osteotomy, synthetic cartilage implants, interpositional arthroplasty, and arthrodesis — and globally these have successful outcomes with low complication rates when done on appropriate patients.[12] The phrase that matters is "appropriate patients," and here's how that's determined.
Grade drives the decision
Coughlin's long-term study of 110 patients established a five-grade clinical and radiographic system and produced the guidance still used today:
- Cheilectomy — reliable success in Grade 1, Grade 2, and selected Grade 3 cases[14]
- Arthrodesis (fusion) — for Grade 4, or Grade 3 with less than 50% of the metatarsal head cartilage remaining at the time of surgery[14]
What the outcomes actually look like
- 97% of patients had a good or excellent subjective result, and 92% of cheilectomies succeeded in pain relief and function[14]
- Cheilectomy produced significant improvement in dorsiflexion and total motion, and both cheilectomy and fusion significantly improved pain and AOFAS scores[14]
- Crucially: a good or excellent outcome did not correlate with the radiographic appearance of the joint at final follow-up[14]
Motion gains by procedure, from a 153-patient series with mean follow-up 26 months: cheilectomy +16°, hemi-implant arthroplasty +20°, decompression metatarsal osteotomy +30°, DMO with hemi-implant +24°. All four groups improved in pain score, with DMO plus hemi-implant showing 99% pain reduction; adhesions were the most common complication across all four.[13]
And the long view — 22 years out
A follow-up of 37 patients (45 toes) at mean 22 years compared fusion, cheilectomy, and Keller's arthroplasty. AOFAS-HMI and VAS pain improved during follow-up only in the arthrodesis patients. No statistically significant differences emerged between groups, but clinically important differences favored arthrodesis, and radiographic disease progression was more evident after cheilectomy. All three were successful operations, with a slight preference for arthrodesis at the very long term.[17]
┌─────────────────────────────────────┐
How I put this together in clinic:
Early-to-moderate disease with cartilage left → cheilectomy. Small operation, fast recovery, 92% success, keeps the joint. The honest caveat is that the arthritis can keep progressing.[14][17]
End-stage disease, or Grade 3 with <50% cartilage → fusion. You lose big toe motion. You gain the most durable pain relief we have, and the 22-year data favor it. Patients walk, hike, cycle, and golf well; the compromise is high heels and deep squatting.[17][14]
Implants and osteotomies have a role, with good short-to-medium-term motion and pain results — I discuss them as options, not defaults.[13]
└─────────────────────────────────────┘
───────────────────────────────────────
PART 6: SURGERY FOR THE MIDFOOT AND HINDFOOT
Fusion is the workhorse here, and that's not a compromise — it's the right answer. The midfoot joints contribute very little motion in the first place, so fusing them costs you almost nothing functionally while removing the pain source. Hindfoot fusion costs more, because those joints handle uneven terrain, so joint selection matters enormously.
- Isolated midfoot (Lisfranc-region) fusion — for arthritis limited to one or two joints, typically the first and second cuneometatarsal. Realignment is part of the operation; fusing in a poor position is worse than not operating.
- Isolated subtalar fusion — for post-calcaneal-fracture or isolated subtalar arthritis. Reliable pain relief; expect reduced tolerance for very uneven ground.
- Double or triple fusion — for combined hindfoot arthritis, often with deformity. Powerful correction, longer recovery.
- Exostectomy (spur removal alone) — occasionally the right small operation when the dominant complaint is a spur rubbing in shoes rather than joint pain. This is where the diagnostic injection earns its keep.
The single most important preoperative variable in this region is alignment. A fusion done in the wrong position transfers load somewhere else, and I'd rather spend an extra visit and a weight-bearing CT getting the plan right.
───────────────────────────────────────
PART 7: ANKLE FUSION VS. TOTAL ANKLE REPLACEMENT
The question I'm asked more than any other in the office. Here's the actual evidence, including where it disagrees.
The randomized trial (TARVA)
303 patients aged 50–85 with end-stage ankle osteoarthritis across 17 UK hospitals; 152 replacement, 151 fusion. At 52 weeks the adjusted difference in the Manchester-Oxford Foot Questionnaire walking/standing score was −5.6 (95% CI −12.5 to 1.4; P=0.12).[18]
Both procedures improved quality of life at one year and both appear safe. The trial was inconclusive regarding superiority of replacement — the confidence interval included both zero and the minimal important difference of 12 — but it could rule out the superiority of fusion.[18]
Complications differed:
- Wound-healing issues: 13.4% (replacement) vs. 5.7% (fusion)[18]
- Nerve injuries: 4.2% vs. under 1%[18]
- Thromboembolic events: 2.9% vs. 4.9%[18]
- Radiographic nonunion after fusion: 12.1%, with only 7.1% symptomatic[18]
A post hoc analysis of fixed-bearing replacements favored replacement (−11.1; 95% CI −19.3 to −2.9; P=0.008) — hypothesis-generating, not definitive.[18]
The 10-year-plus data (COFAS)
211 patients, minimum 10 years, mean 13.2 years of follow-up. The groups differed at baseline — fusion patients were younger (53.8 vs. 61.3 years), smoked more, and had less inflammatory arthritis.[5]
Result: the two groups demonstrated similar functional outcomes. But fusion patients had a greater chance of having no further surgery after the index procedure (70% vs. 58%; P=0.02). The authors' conclusion: long-term outcomes were similar in a cohort where treatment was tailored to the condition of the patient.[5]
The prospective multicenter cohort
517 patients who had failed nonoperative care. At 24 months, mean improvement was significantly greater with replacement — FAAM activities-of-daily-living difference 9 points (95% CI 3–15) and SF-36 physical component 4 points (95% CI 1–7). Crude revision and complication risks were higher in the fusion group, but those differences were no longer significant after adjusting for age, sex, BMI, and comorbidity index.[19]
Notably, treatment success differed by patient profile: replacement outperformed fusion in patients with higher comorbidity burden (80% vs. 62%) and those not fully employed (81% vs. 58%), but results were similar in healthier patients and those working full time (79% vs. 78%).[19]
Where the evidence conflicts
A meta-analysis of third-generation implants found replacement gave better AOFAS function and better range of motion, but significantly higher complication and reoperation rates, with no significant difference in pain relief, gait analysis, or satisfaction.[20]
┌─────────────────────────────────────┐
Four high-quality bodies of evidence. Four somewhat different complication pictures. What every one of them agrees on: both operations relieve pain, both improve function, and neither is superior for everyone.[5][19][18][20]
Anyone who tells you one is simply better is going beyond what we know.
└─────────────────────────────────────┘
How the decision actually gets made
Factor | Points toward fusion | Points toward replacement | Reference |
Age | Younger; fusion cohorts averaged 53.8 years | Older; replacement cohorts averaged 61.3 years | |
Work demand | Heavy labor, ladders, uneven ground | Lower-demand work; benefit was larger in those not fully employed | |
Comorbidity burden | Fewer comorbidities — outcomes similar | Higher comorbidity index favored replacement (80% vs 62% success) | |
Alignment | Significant deformity or malalignment | Well-aligned ankle | |
Bone quality | Poor bone stock | Good bone stock | |
Neighboring joints | Healthy adjacent joints | Adjacent joints already arthritic | |
Prior deep infection | Strongly favors fusion | Contraindicated | — |
Smoking | Higher nonunion risk; wound risk either way | Higher wound complication risk (13.4%) | |
Wanting to avoid more surgery | 70% had no further surgery vs 58% | — | |
Wanting to keep motion | — | Better ROM and function scores |
What I tell patients, plainly
- Fusion trades motion for durability. It reliably relieves pain and is less likely to need another operation. You notice it on stairs, slopes, and rough ground, and the neighboring joints absorb more work over the years.
- Replacement preserves motion and produced better function scores in several cohorts — but it is a mechanical device with a finite life, and fewer patients get through the long term without additional surgery.[5][19]
- The right answer depends on your age, job, alignment, bone, health, and what you most want to be doing at 75. Shared decision-making here isn't a courtesy; the data genuinely will not decide for you.
The COFAS authors put it best: outcomes were similar in a cohort where treatment was tailored to the patient. That's the whole game.[5]
───────────────────────────────────────
PART 8: RECOVERY TIMELINES
Procedure | Weight-bearing | Immobilization | Desk work | Full recovery |
Cheilectomy (big toe) | Immediate, stiff shoe | 2–4 weeks | 1–2 weeks | ~3 months |
Hemi-implant / osteotomy | Protected early | 3–6 weeks | 1–2 weeks | 3–4 months |
First MTP fusion | Heel-weight-bearing early | ~6 weeks | 1–2 weeks | 3–4 months |
Midfoot fusion | Non-weight-bearing 6–8 weeks | 8–12 weeks | 2–4 weeks | 6–12 months |
Subtalar / hindfoot fusion | Non-weight-bearing 6–10 weeks | 10–12 weeks | 2–4 weeks | 9–12 months |
Ankle fusion | Non-weight-bearing 6–12 weeks | ~12 weeks | 2–4 weeks | 9–12 months |
Total ankle replacement | Protocol-dependent, often earlier | 4–8 weeks | 2–4 weeks | 6–12 months |
Ranges vary with bone quality, additional procedures, and medical conditions.
What predicts success more than technique: not using nicotine, controlling blood sugar, following weight-bearing restrictions exactly, and finishing therapy. Nonunion after ankle fusion was radiographically present in 12.1% in TARVA — and nicotine is the largest modifiable contributor.[18]

(CONTINUED FROM PART 9)
───────────────────────────────────────
PART 9: STAYING ACTIVE — SPORT BY SPORT (CONTINUED)
Manageable with modification (continued):
- Dance and gymnastics — big toe arthritis is the limiter. Relevé and pointe load the first MTP joint maximally, and this is the population where a cheilectomy can be genuinely career-preserving because it restores dorsiflexion rather than eliminating it.[1]
- Baseball and softball — the back foot in the batting stance and the push-off foot on the mound are the stress points. A stiff insert in the cleat helps more than most people expect.
- Volleyball — repetitive landing loads the ankle and hindfoot. Bracing and reduced practice volume usually keeps players in.
Harder, but not automatically off the table:
- Running — possible with mild disease, cushioned shoes, softer surfaces, and reduced weekly volume. Often the first activity to go with ankle or hindfoot arthritis. Cross-training preserves fitness while you find your ceiling.
- Basketball, soccer, football, CrossFit — repetitive impact plus cutting. Not forbidden, but symptoms set the volume, and a bad flare costs weeks.
After fusion or replacement, the guidance is low-impact activity indefinitely: walking, hiking, cycling, swimming, golf, doubles tennis, and strength training. Running and jumping sports are discouraged after either operation — impact loads a replacement's bearing surface and drives load into the joints adjacent to a fusion, which matters given that fusion patients already carry a long-term adjacent-joint burden.[2]

───────────────────────────────────────
PART 10: THE MISTAKES I SEE MOST
1. Accepting "it's just arthritis, learn to live with it." Population data show three-quarters of people with symptomatic radiographic foot arthritis report disabling foot pain.[3] That is a treatable problem, not a life sentence.
2. Getting a non-weight-bearing X-ray and being told it's normal. Every major foot arthritis study uses standing dorsoplantar and lateral views for a reason.[3][4]
3. Buying soft, cushioned, flexible shoes for big toe or midfoot arthritis. Instinct says cushion. Mechanics say stiff. A shoe that bends where your joint hurts makes the pain worse.[5]
4. Chasing injections before doing the mechanical work. Offloading, weight management, and strengthening are cheaper, better supported, and more durable than most injectables.[6][7][8]
5. Paying out of pocket for PRP or stem cells for arthritis. The evidence does not currently support routine use in this setting.[6]
6. Ignoring gout. A gout history was associated with incidence or progression of foot arthritis (aOR 2.75; 95% CI 1.24–6.07). Controlling it protects joints.[4]
7. Fusing the wrong joint. When three neighboring joints look bad on film, a diagnostic numbing injection identifies the real culprit. Skipping that step is how patients end up with a well-healed fusion and unchanged pain.
8. Continuing nicotine through a planned fusion. It influences the outcome more than any technical decision I make in the operating room.[9]
9. Assuming the surgery decision is the surgeon's to make. In ankle arthritis specifically, the evidence does not choose between fusion and replacement. Your job, age, alignment, and goals do.[9][2][10]
───────────────────────────────────────
PART 11: COMPLICATIONS, STATED PLAINLY
From nonoperative care:
- NSAID risk — GI, renal, and cardiovascular events, especially in older adults with comorbidities, who should be closely monitored.[6]
- Acetaminophen — there are increasing concerns regarding its effectiveness and safety in osteoarthritis.[5]
- Progressive deformity if a collapsing arch or unstable ankle goes unaddressed.
From surgery in general: infection, wound-healing problems, nerve injury, blood clot, stiffness, and persistent pain.
Specific to big toe surgery: across cheilectomy, hemi-implant arthroplasty, and decompression osteotomy, adhesions were the most common complication in all groups.[11] After cheilectomy, radiographic disease progression was more evident at long-term follow-up than after fusion.[12]
Specific to fusion (ankle):
- Nonunion — 12.1% radiographically in TARVA, 7.1% symptomatic[9]
- Malunion — position is everything; a fusion in poor alignment transfers load elsewhere
- Adjacent joint arthritis over the long term
Specific to total ankle replacement:
- Wound-healing issues 13.4% and nerve injury 4.2% in TARVA[9]
- Higher reoperation burden long term — at 10+ years, 70% of fusion patients had no further surgery vs. 58% of replacement patients (P=0.02)[2]
- Higher complication and reoperation rates in the third-generation implant meta-analysis, though crude differences in the prospective multicenter cohort lost significance after adjustment for age, sex, BMI, and comorbidity[13][10]
- Loosening, subsidence, and eventual revision — it is a mechanical device with a finite lifespan
- Contraindicated after prior deep joint infection
Modifiable risk factors I address before any operation: nicotine in any form, glycemic control, vascular status, neuropathy, and body weight.
───────────────────────────────────────
PART 12: PROGNOSIS — THE PART PATIENTS LEAST EXPECT
- Radiographic worsening is common; symptomatic worsening is not. Over roughly 3 years, 55% of feet with existing arthritis progressed on X-ray, but only 16% of those became symptomatic.[4]
- Your film does not forecast your function. Joint damage on imaging does not indicate how much your osteoarthritis will affect you.[7]
- Osteoarthritis is not an inevitable part of getting older.[7]
- Most patients never reach the operating room. Education, exercise, weight management, and mechanical offloading control symptoms for the majority.[6][7]
- When surgery is needed, it works. 97% good or excellent subjective results in Coughlin's big toe series; both ankle operations improved quality of life in TARVA; similar functional outcomes at a mean of 13.2 years in COFAS.[9][2][1]
- Weight loss pays off proportionally — a clear dose-response between amount lost and improvement in pain and function.[7]
The goal is never a normal X-ray. The goal is a full workday, a walk through the neighborhood, a round of golf, and sleeping through the night. Those are achievable at nearly every stage of this disease.
───────────────────────────────────────
PART 13: PREVENTION AND SLOWING IT DOWN
Manage body weight. The strongest modifiable factor in the foot data: obesity carried >2× the odds of radiographic and >5× the odds of symptomatic foot arthritis, and BMI predicted new arthritis and worse function on every FAOS subscale.[14][4]
Keep moving and keep strong. Exercise has high-quality evidence for reducing pain and improving motion, with effect sizes of 0.4–0.5.[7]
Control gout. Associated with incidence and progression of foot arthritis.[4]

FREQUENTLY ASKED QUESTIONS
1. How common is foot arthritis?
Foot osteoarthritis is as prevalent as knee osteoarthritis. Symptomatic radiographic foot arthritis affects[6] 16.7% of community-dwelling adults over 50 — roughly one in six.[3]
2. Which joint is affected most often?
The big toe joint (7.8%), then the second cuneometatarsal (6.8%), talonavicular (5.8%), navicular-first cuneiform (5.2%), and first cuneometatarsal (3.9%).[3]
3. Is foot arthritis actually disabling?
For most people who have it, yes — three-quarters of those with symptomatic radiographic foot arthritis reported disabling foot pain.[3]
4. Why did I get this? I'm not that old.
Body weight, prior injury, gout, and sex are all contributors. Obesity carried more than five times the odds of symptomatic foot arthritis, and women were substantially more likely to develop new foot arthritis (aOR 4.10).[14][4]
5. Does gout cause arthritis damage in the foot?
A gout history was associated with incidence or progression of foot radiographic arthritis (aOR 2.75; 95% CI 1.24–6.07).[4]
6. My X-ray says severe. Am I going to end up unable to walk?
Almost certainly not. Over ~3 years, 55% of arthritic feet worsened on X-ray but only 16% of those became symptomatic, and joint damage on imaging does not indicate how much arthritis will affect you.[7][4]
7. My foot hurts but the X-ray was called normal. What now?
Ask two questions: were you standing, and were both dorsoplantar and lateral views taken? Those are the standard in every major foot arthritis study.[3][4]
8. Is there a blood test or a definitive test for this?
No. There are no accepted clinical diagnostic criteria for foot or ankle osteoarthritis, which is why imaging plus a careful exam is the approach.[6]
9. Do I need an MRI?
Usually not at the first visit. It's for suspected cartilage lesions, bone marrow edema, or coexisting tendon and ligament problems.
10. What is a diagnostic injection, and why would I need one?
When several neighboring joints look arthritic, numbing one identifies which is generating pain. It prevents operating on the wrong joint.
11. Where do I start with treatment?
12. Will exercise wear my joints out faster?
No. Exercise is a key element of osteoarthritis management, with high-quality evidence for decreasing pain and improving motion.[7]
13. How much weight loss actually matters?
There is a dose-response relationship — more loss, more improvement — and diet plus exercise beats either alone.[7] Given obesity's >5× odds of symptomatic foot arthritis, this is the highest-leverage change available.[14]
14. What shoes should I wear?
For big toe and midfoot arthritis: stiff-soled or rocker-sole shoes, shoe-stiffening inserts, accommodative insoles, or functional foot orthoses.[5] For hindfoot and ankle: supportive, cushioned shoes, often with a brace.
15. Why stiff instead of cushioned?
Because cushion doesn't stop the joint from bending, and bending is what hurts. A carbon fiber footplate is often the single most effective non-surgical intervention for big toe arthritis.[5]
16. Should I use a brace or a cane?
For ankle arthritis, offloading by brace, cane, rocker sole, or insert is standard clinical practice, though the Cochrane review notes the supporting evidence is limited.[8]
17. What medication should I try first?
Topical NSAIDs or capsaicin, then acetaminophen, then an oral NSAID or COX-2 inhibitor if relief is inadequate.[6]
18. Are NSAIDs safe to take long term?
They carry real GI, renal, and cardiovascular risk, and older patients on NSAIDs should be closely monitored.[6] Topical formulations make particular sense in the foot, where joints sit just under the skin.
19. Is Tylenol a good option?
It's in the stepwise pathway, but there are increasing concerns regarding the effectiveness and safety of acetaminophen in osteoarthritis.[5]
20. Do glucosamine and chondroitin work?
Benefit for pain reduction has not been shown.[8]
21. Should I get a cortisone shot?
It's a recognized pharmacological option and it's useful for a flare, an event, or a diagnostic question.[5] It is not a long-term plan.
22. Do gel shots work in the ankle?
There is some evidence they may be effective in the short term for ankle OA.[6] The 2026 AAOS ankle guideline does not support hyaluronic acid used alone. That disagreement is real, and worth discussing before paying for a series. Ankle Arthritis Treatment in DFW: What the 2026 AAOS Guidelines Mean for You
23. What about PRP or stem cells?
The evidence base does not currently support routine use for foot and ankle arthritis, and robust clinical trials are urgently needed in this area generally.[6]
24. What is a cheilectomy?
Removal of the dorsal spur from the big toe joint, preserving the joint. It succeeded in 92% of cases, with 97% good or excellent subjective results in the overall series, and it significantly improved dorsiflexion.[1]
25. Who is a candidate for cheilectomy versus fusion of the big toe?
Cheilectomy is reliable in Grade 1, Grade 2, and selected Grade 3 disease. Fusion is indicated for Grade 4, or Grade 3 with less than 50% of the metatarsal head cartilage remaining at surgery.[1]
26. If I fuse my big toe, what do I lose?
Motion at that joint — which means high heels and deep squatting. What you gain is the most durable pain relief available: at mean 22 years, pain and function scores improved during follow-up only in the arthrodesis group, with clinically important differences favoring fusion.[12]
27. Will my arthritis keep progressing after a cheilectomy?
It can. Radiographic disease progression was more evident after cheilectomy than after fusion at long-term follow-up — but note that in Coughlin's series, a good or excellent outcome did not correlate with the radiographic appearance of the joint.[1][12]
28. What about big toe implants?
Hemi-implant arthroplasty gained +20° of motion, decompression osteotomy +30°, and the combination +24°, versus +16° for cheilectomy, with pain improvement in all groups. Adhesions were the most common complication across every group.[11]
29. Is midfoot fusion a big loss of motion?
Very little functionally. Those joints contribute minimal motion, so fusing them removes the pain source at low cost. Alignment during the fusion is what determines the result.
30. Fusion or total ankle replacement — which should I choose?
Neither wins outright. TARVA found no significant difference at 52 weeks (−5.6; 95% CI −12.5 to 1.4; P=0.12), with both improving quality of life.[9] COFAS at 10+ years found similar functional outcomes.[2] A prospective multicenter study favored replacement at 24 months (FAAM-ADL difference 9 points; 95% CI 3–15).[10] A meta-analysis favored fusion on complications.[13]
31. Which one is less likely to need another operation?
Fusion. At a minimum of 10 years, 70% of fusion patients had no further surgery versus 58% of replacement patients (P=0.02).[2]
32. Does my overall health change the recommendation?
It appears to. Replacement outperformed fusion in patients with higher comorbidity burden (80% vs. 62% success) and those not fully employed (81% vs. 58%), while results were similar in healthier, fully employed patients (79% vs. 78%).[10]
33. Will I limp after an ankle fusion?
Most patients walk well on level ground. The difference appears on stairs, ramps, and uneven terrain, where ankle motion normally accommodates.
34. How long will an ankle replacement last?
It is a mechanical device that can loosen, subside, and require revision, and the long-term data show more additional surgery than after fusion.[2] Plan for the possibility.
35. What is the risk my fusion won't heal?
12.1% radiographic nonunion in TARVA, with 7.1% symptomatic. Nicotine is the biggest modifiable contributor.[9]
36. Do I really have to stop nicotine?
For any fusion, yes. It affects the outcome more than the technical details of the operation.
37. Can I still play pickleball?
Usually — supportive court shoe, brace if the ankle or hindfoot is involved, doubles rather than singles, and non-consecutive playing days. This is the most common question in my McKinney and Flower Mound clinics.
38. Can I run with arthritis?
With mild disease, yes, at reduced volume on softer surfaces. After fusion or replacement, running is generally discouraged.
39. What activities are always safe?
Cycling, swimming, elliptical, rowing, golf, and strength training.
40. When should I see a foot and ankle specialist?
When pain has persisted several months, when it limits walking, work, or sleep, when the foot is changing shape, when a joint keeps swelling, or when you've been offered injections or surgery without a full discussion of alternatives.
41. What should I bring to the visit?
Prior X-rays and MRI reports (images, not just reports), a list of everything tried and for how long, the shoes you wear most days, and one specific sentence about what you want to get back to doing.

THE BOTTOM LINE
- Foot arthritis is as common as knee arthritis, affects 1 in 6 adults over 50 symptomatically, and disables three-quarters of those it affects.[6][3]
- The big toe and midfoot lead by frequency; the ankle is less common but most limiting.[3]
- Body weight is the most modifiable risk factor — >5× odds of symptomatic foot arthritis with obesity.[14]
- X-ray progression rarely means symptom progression — 55% vs. 16%.[4]
- Education, exercise, weight management, then mechanical offloading — stiff soles, rockers, orthoses, braces.[6][7][8][5]
- Injection evidence is limited; corticosteroid is short-term, hyaluronic acid modest and disputed, PRP and stem cells unsupported for routine use.[6][5]
- Big toe surgery is graded: cheilectomy for Grades 1–3 with cartilage remaining (92% success), fusion for Grade 4 or <50% cartilage, with 22-year data favoring fusion.[1][12]
- Ankle fusion and replacement both work. Similar function at 13 years; fusion needs less further surgery; replacement may favor higher-comorbidity patients.[9][2][10]
- Most people never need surgery at all.
