PART 12: RETURN TO WORK
- Desk work — usually 1–2 weeks after surgery; often uninterrupted entirely with tendinopathy treated nonoperatively
- Standing or retail work — 6–12 weeks after surgery; supportive footwear and a cushioned mat matter more than people expect
- Nursing, teaching, hospitality — high step counts. Plan on 8–12 weeks post-surgery, and expect end-of-day swelling for several months beyond that
- Construction, warehouse, first responder — 3–6 months after tendon surgery; longer for posterior tibial reconstruction, which involves bone work
- Driving — the limiting factor is often the right foot and the boot, not the tendon itself: When Can I Drive After Ankle Fracture Surgery?
A practical point for anyone in a physically demanding job: light duty is almost always better than full leave. Complete inactivity deconditions the tendon, and tendon needs load to remodel.[1] I would rather write restrictions than a full work release.
───────────────────────────────────────
PART 13: THE MISTAKES I SEE MOST OFTEN
1. Complete rest. The most common and most costly error. Rest reduces pain temporarily and does nothing for the underlying failed healing response.[1] The tendon is weaker when you come back, and the pain returns within two weeks. Loading exercise therapies far surpass a wait-and-see policy.[2]
2. Waiting for zero pain before starting exercise. Activity limited to a self-monitored pain level of 2 to 5 out of 10 did not limit improvement during strength training.[2] Some discomfort during rehab is expected and acceptable.
3. Stopping the program at 6 weeks because it's working. Twelve weeks is the minimum for the strength protocols that have been studied, and gains in the eccentric Achilles trial continued out to one year.[2][3]
4. Assuming a lingering "ankle sprain" is just slow. Lateral pain three months after a sprain is often a peroneal tendon tear, and peroneal problems are frequently missed.[4][5]
5. Ignoring a collapsing arch. Untreated posterior tibial tendinopathy may progress to a painful flatfoot requiring extensive reconstruction.[5] Early is a tendon operation; late is a bone operation.
6. Steroid injection into a load-bearing tendon. Real rupture risk, and prior corticosteroid exposure is itself a risk factor for posterior tibial tendinopathy.[6][7]
7. Chasing injectables first. PRP has shown no significant effect in well-controlled tendinopathy studies, and there is minimal clinical evidence supporting injectables around tendons generally.[2][1]
8. Doing generic stretches for a specific tendon. Completing a tendon-specific FHL program was strongly protective against needing surgery (OR 0.15).[8]
9. Treating the tendon and ignoring the mechanics. A varus hindfoot keeps overloading the peroneals; a pronated foot keeps overloading the posterior tibial.[7][4] Recurrent instability keeps producing peroneal microtrauma.[5]
10. New sport, old conditioning. The classic history is a change in activity.[6] Ramp up over months, not weeks.
───────────────────────────────────────
PART 14: COMPLICATIONS
Of the condition, untreated:
- Progression to rupture — occurs in about 4% of Achilles tendinopathy, most often in older adults[5]
- Fixed flatfoot deformity from posterior tibial failure, converting a tendon problem into a reconstruction[5]
- Recurrent peroneal dislocation and secondary tendon tearing
- Chronic pain and deconditioning from prolonged avoidance
Of surgery — every tendon operation shares a similar risk profile:
- Wound healing problems, particularly over the Achilles where skin is thin and blood supply is limited
- Infection
- Nerve injury — the sural nerve near the Achilles and peroneals, the tibial nerve medially
- Persistent pain despite technically successful surgery
- Stiffness and weakness requiring prolonged rehabilitation
- Rerupture — 0.6% to 3.5% after surgical Achilles repair, depending on technique[5]
- Blood clot (DVT) — a genuine risk with any lower extremity immobilization
Smoking, diabetes, and higher BMI increase most of these risks and are also intrinsic risk factors for the tendon disease itself.[7] Stopping nicotine before surgery is the highest-value single thing a patient can do.

PART 15: PROGNOSIS
The overall outlook is good, and this deserves emphasis because patients arrive discouraged.
- Eccentric loading for Achilles tendinopathy produced VISA-A improvement from 60.7 to 89.4 at one year — far exceeding the minimal clinically important difference of 7.37.[3]
- Across tendinopathies, eccentric overloading produced a 29% to 94% reduction in pain intensity.[9]
- 44% of FHL patients avoided surgery with a dedicated stretching program.[8]
- Peroneal groove deepening with retinacular repair returned all patients to their pre-injury gait in one series.[10]
- Patients with low functional demands generally do well nonoperatively; those with high demands who fail nonoperative care generally do well with surgery.[5]
Two prognostic factors are within your control: how early you start — recovery is faster the shorter the symptoms have been present in recreational athletes — and whether you complete the program.[2][8]
───────────────────────────────────────
PART 16: PREVENTION
- Progress load gradually. A change in activity is the most common precipitant.[6]
- Strength-train year-round. Calf raises, eccentric heel drops, and single-leg balance work are preventive, not just rehabilitative.[9]
- Know your foot shape. High arch and varus hindfoot → protect the peroneals with lateral posting. Flat, pronated foot → arch support for the posterior tibial.[7][4]
- Fix instability. Repeated rolling drives peroneal microtrauma. Ankle Sprains and Chronic Ankle Instability[5]
- Replace shoes before they're dead. Court shoes for court sports; running shoes for running.
- Address modifiable medical risk — BMI, blood pressure, glucose control, nicotine.[7]
- Respect a 5–10 single-leg heel raise standard. If you can't do it, you have a deficit worth addressing before it becomes a diagnosis.[5]

FREQUENTLY ASKED QUESTIONS
1. Is it tendonitis or tendinopathy?
Almost certainly tendinopathy. The pathology is degeneration without substantial inflammation — a failed healing response, not an inflammatory one.[11][6][1] The distinction changes treatment: loading, not anti-inflammatories.
2. Why hasn't resting fixed it?
Because rest doesn't remodel a degenerated tendon. Loading exercise therapies far surpass non-loading therapies or a wait-and-see approach.[2]
3. How long until I feel better?
Twelve weeks of loading is the minimum studied, with meaningful gains often at 3–6 months and continued improvement to one year.[2][3]
4. Should I take ibuprofen?
Short-term use can reduce pain and improve motion enough to let you complete rehab, which is its real value.[6] Trials of naproxen, piroxicam, and topical diclofenac showed no significant benefit over placebo for tendinopathy itself.[2][12]
5. Will a cortisone shot help?
Care must be taken injecting corticosteroid into or near major load-bearing tendons because of rupture risk.[6] I do not inject steroid around the Achilles or posterior tibial tendon.
6. What about PRP?
Well-controlled studies have shown no significant effect of PRP for tendinopathy, and evidence for injectables around tendons generally is minimal.[2][1]
7. Does shockwave therapy work?
It has reasonable support in Achilles tendinopathy, with improved AOFAS and VISA-A scores in a meta-analysis of 8 trials — though the VISA-A difference was below the MCID. Combining shockwave with eccentric training outperforms either alone.[1][12]
8. Can I keep exercising?
Usually yes. Keeping pain between 2 and 5 out of 10 did not limit improvement during strength training.[2]
9. What exactly are eccentric heel drops?
Stand on a step with weight on the ball of the affected foot, slowly lower the heel below the forefoot, then use the other leg to return up. Three sets of 15, twice daily, knee straight then slightly bent.[3]
10. Is my pain the Achilles or the heel bone?
Midportion disease sits 2–6 cm above the insertion; insertional disease is at the heel itself.[13] They're treated differently: Insertional vs. Midportion Achilles Tendinopathy
11. How do I know if my Achilles is torn rather than just sore?
A palpable gap, an abnormal lump, limited plantarflexion on calf squeeze, and increased passive dorsiflexion suggest rupture. [5]Can You Walk on a Torn Achilles Tendon?
12. My ankle sprain still hurts on the outside after three months. Why?
Very often a peroneal tendon problem — commonly missed and commonly mistaken for a slow sprain.[4][5]
13. What does "too many toes" mean?
Viewed from behind, more toes are visible on the affected side because the foot has rotated outward — a sign of posterior tibial tendon dysfunction with flatfoot.[4]
14. Why can't I do a single-leg heel raise?
You should be able to do 5 to 10 without difficulty. Inability is a meaningful sign of posterior tibial dysfunction.[5]
15. Will my flat foot get worse?
Untreated posterior tibial tendinopathy may progress to a painful flatfoot requiring extensive reconstruction.[5] This is the one where waiting genuinely costs you options.
16. Do orthotics actually help?
For early-stage PTTD, a systematic review of 4 RCTs found orthoses may reduce pain, with orthoses plus exercise better than orthoses alone, and personalized arch support better than flat insoles — though most trials were at high risk of bias.[5]
17. I'm not a dancer. Can I still have "dancer's tendinitis"?
Yes. FHL tendonitis is more common than previously thought and frequently occurs in nonathletes.[8]
18. Why did it take so long to diagnose my FHL problem?
Most patients in the largest series had been previously seen by orthopedic providers who did not appreciate the condition, with diagnostic delays exceeding a year.[8]
19. Do I need an MRI?
Often not initially. Diagnosis rests primarily on history and physical exam, with X-ray reasonable first and ultrasound or MRI when the picture is unclear.[6][14]
20. Why did you order an ultrasound instead of an MRI?
Because subluxation is dynamic. A tendon that snaps out of its groove during motion can look normal on a static MRI; dynamic high-resolution ultrasound shows it.[5]
21. What determines whether my peroneal tendon is repaired or tenodesed?
The amount of viable tendon: repair and tubularization for tears under 50%, tenodesis for tears over 50%.[14]
22. Why do my tendons keep dislocating?
Often anatomy — a flat or convex retromalleolar groove, a low-lying peroneus brevis, an accessory peroneus quartus, or an os peroneum.[5] Surgery may include deepening the groove and repairing the retinaculum.[14]
23. When is surgery the right call?
Broadly: failed nonoperative care over an appropriate window — 3 to 6 months for posterior tibial — plus high functional demand.[4][5] Recurrent peroneal dislocation in athletes is often addressed sooner.[14]
24. Will surgery definitely fix the pain?
No operation is guaranteed. Persistent pain despite technically successful surgery is a recognized outcome, which is why the diagnosis has to be right first.
25. Am I too old for this to get better?
No. In the eccentric Achilles data, response was robust, and nonoperative care works well across ages. Age does raise rupture risk in existing tendinopathy.[3][5]
26. Can I run through this?
Often, at reduced volume within the 2–5 pain range.[2] What I don't allow is running through a suspected rupture or a collapsing arch.
27. How soon can I get back to pickleball?
Peroneal tendinopathy commonly settles over 6–12 weeks nonoperatively; after repair, 3–4 months. Lateral drills must come before match play.
28. Do I need to stop nicotine?
Yes, if surgery is on the table. Nicotine impairs healing and raises wound and infection risk substantially.
29. Could this be something other than a tendon?
Yes — stress fracture, cartilage lesion, arthritis, plantar fasciitis, or nerve pain such as Morton neuroma, which causes burning ball-of-foot pain with numbness into the third and fourth toes.[15]
30. Are peptides or stem cells worth trying?
The evidence does not support them for tendinopathy at this time. [2][1]The Real Science Behind Peptides and Healing Orthopedic Injuries
31. What should I bring to my appointment?
Any prior X-rays or MRI reports, a list of everything already tried and for how long, your current and prior shoes, and your activity goal stated specifically.
32. What's the single most important thing I can do today?
Start a supervised, progressive loading program for the correct tendon — and commit to twelve weeks.[2][9]

THE BOTTOM LINE
- Five tendons — Achilles, peroneal, posterior tibial, tibialis anterior, FHL — account for nearly all foot and ankle tendon pain.
- Progressive loading, especially eccentrics, is the best-evidenced treatment across tendinopathies.[2][9]
- Rest alone fails. Loading beats a wait-and-see approach.[2]
- NSAIDs and PRP underperform expectations; steroid near load-bearing tendons carries rupture risk.[6][2][12]
- Posterior tibial dysfunction is the time-sensitive one — untreated, it becomes a reconstruction.[5]
- FHL is under-diagnosed, and a tendon-specific stretching program let 44% avoid surgery.[8]
- Earlier treatment recovers faster in recreational athletes.[2]
