THE SHORT ANSWER
Movement matters more than the therapy appointment.
Active ankle exercise after surgery gets patients back to work roughly 21 days earlier than immobilization, with no increase in complications.[1] Starting range of motion within the first week after surgery does not increase complications or reoperations.[2]
But here's the part most articles won't tell you: in large randomized trials, supervised physical therapy has not clearly outperformed good self-management advice for the average ankle fracture.[3][4]
What that means practically: everyone needs to move the ankle. Not everyone needs 20 visits.
└─────────────────────────────────────┘
I want to be straight with you in this article, because rehab is the phase where patients get the most conflicting advice — from surgeons, therapists, the internet, and the friend who broke their ankle in 2019.
───────────────────────────────────────
WHY REHAB MATTERS AT ALL
Surgery fixes the position of the bone. It doesn't fix what happens to the leg while the bone heals.
Three things go wrong during immobilization:
- The calf shrinks. Muscle is lost far faster than it's regained. This is why the injured leg looks visibly smaller at six weeks.
- The ankle stiffens. Dorsiflexion — pulling the toes up toward the shin — is the motion you lose first and fight hardest to get back. It's also the motion you need most for walking normally, going down stairs, and squatting.
- Balance disappears. The nerve feedback loop that keeps you steady on one leg degrades quickly and does not return on its own.
Rehab exists to reverse those three things. That's it. Everything below is in service of those goals.
───────────────────────────────────────
THE PART THAT SURPRISES PATIENTS: WHAT THE EVIDENCE ACTUALLY SHOWS
This is the honest core of the article, and I'd rather you hear it from me than discover it later.
The EXACT trial, published in JAMA, randomized patients after ankle fracture immobilization to either a supervised, individually tailored exercise program with a physical therapist, or to a single session of self-management advice with a handout.[3]
The supervised group got ankle mobility and strengthening exercises, stepping exercises, weight-bearing and single-leg balance work, and gait training — a genuinely well-designed program.[3]
The Cochrane review summarized the result: little or no difference in activity limitation at six months between the supervised exercise class and advice alone (MD 0.00, 95% CI −3.59 to 3.59; 170 participants).[4]
And EXACT wasn't an outlier. Across the Cochrane review, comparing different physical therapy approaches after the initial fracture management period, multiple trials found little or no difference:[4]
Trial | Comparison | Result |
Keene 2022 | 16-week progressive exercise program vs. best-practice advice | Little or no difference at 6 months |
Lin 2008 | Enhanced physiotherapy sessions vs. usual care | Little or no difference at 24 weeks |
Moseley 2005 | Added stretching vs. home program | Little or no difference at 12 weeks |
Moseley 2015 (EXACT) | Supervised exercise class vs. advice | Little or no difference at 6 months |
Nilsson 2009 | 12 weeks of twice-weekly neuromuscular physiotherapy vs. usual care | Little or no difference at 6 months |
An important caveat on certainty. Cochrane rated this evidence very low certainty — downgraded for risk of bias and twice for imprecision, because each therapy type was tested in few participants and the confidence intervals included benefit in either direction. The trials were also too different in design to combine.[4]
┌─────────────────────────────────────┐
"No clear difference" is not the same as "physical therapy doesn't work." It means we haven't shown that supervised sessions beat well-delivered advice for the average patient.
└─────────────────────────────────────┘
Why this doesn't make me stop referring patients to PT. Because "advice alone" in those trials meant structured, physical-therapist-delivered, illustrated, specific advice — not "walk it off." Most patients don't get that. And because averages hide individuals: a 70-year-old living alone, a trimalleolar fracture-dislocation, and a competitive soccer player are not the average patient in a trial. I believe formal physical therapy after ankle fracture surgery is important.
What it does change is how I use PT. I use it selectively and purposefully, not as an automatic 3-times-a-week prescription for everyone.
───────────────────────────────────────
WHERE THE EVIDENCE IS STRONG: MOVE EARLY
While supervised sessions haven't clearly beaten advice, the timing of movement has strong support.
Active exercise beats immobilization. A meta-analysis of 25 studies found ankle exercises produced return to work and daily activities a mean of 20.8 days earlier than immobilization (95% CI −40.02 to −1.50), with no difference in complications (RR 1.22, 95% CI 0.60 to 2.45).[1]
Very early motion is safe. A study of 299 ORIF patients — including 77 bimalleolar and 138 trimalleolar fractures — defined "very early" range of motion as starting between postoperative day 2 and day 7. Among the 116 patients (38.8%) who started that early, survival analysis showed no increase in complications (adjusted HR 1.12) or reoperations (adjusted HR 0.68).[2]
Structured early motion beats casting. The EMADE trial randomized 157 patients after Weber B ORIF, at two weeks post-op, to lightweight cast immobilization or a progressive home exercise program with weekly advice and education. Both groups stayed non-weight-bearing until six weeks.[5]
At 12 weeks, the exercise group scored a mean OMAS of 62.0 vs. 48.8 — a clinically meaningful difference of 13.2 (95% CI 5.66 to 20.73; p<0.001). The advantage persisted at 24 weeks and converged by 52 weeks. No intervention-related adverse events, including instability, were reported.[5]
Note the important detail: EMADE was a home exercise program with weekly advice, not intensive supervised therapy. That's consistent with everything above — the movement is what matters.
┌─────────────────────────────────────┐
Early motion produces a faster recovery. By one year, the groups tend to look the same. Getting there sooner is still worth a great deal.[5]
└─────────────────────────────────────┘
───────────────────────────────────────
AND EARLY WEIGHT-BEARING REDUCES HOW MUCH PT YOU NEED
A 2026 randomized trial of 52 patients with unstable ankle fractures compared early weight-bearing and mobilization starting at 2 weeks against continued non-weight-bearing until 6 weeks.[6]
The early group returned to work faster (41.4 vs. 51.9 days, p<0.001), had significantly higher OMAS scores from 6 weeks onward, and had range of motion advantages that persisted through 12 months. Wound complications were comparable (3.8% vs. 7.7%, p=0.552).[6]
The most striking finding for this article:
85% of the early weight-bearing group needed fewer than 8 physical therapy sessions, compared with 11.5% of the delayed group (p<0.001).[6]
The authors appropriately caution that this was a modest single-center sample requiring confirmation in larger studies.[6]
Still, the direction is clear: walking sooner is itself a form of rehabilitation. More detail here: Walking on a Broken Ankle: When Is It Safe?

THE PHASE-BY-PHASE PLAN
This is what I actually prescribe. Timelines shift based on your fracture, your fixation, and your medical history.
PHASE 1 — WEEKS 0 TO 2: PROTECT AND ELEVATE
The wound is the priority. Nothing else matters if the incision fails.
- Elevate above heart level as much as possible. This is the highest-value thing you control.
- Toe wiggling — every hour you're awake. Keeps the tendons gliding.
- Knee and hip motion — straight leg raises, knee bends, hip work. The rest of the leg does not need to shut down.
- Upper body and opposite leg conditioning — protects your overall fitness.
- Non-weight-bearing, splint stays dry.
PHASE 2 — WEEKS 2 TO 6: MOTION BEGINS
Splint comes off, stitches out, boot goes on. This is the pivot point.
- Ankle range of motion out of the boot — up/down (dorsiflexion/plantarflexion) first, then gentle side-to-side. Very early motion in this window is safe.[2]
- The alphabet drill — trace letters with your big toe. Simple and effective.
- Gentle isometrics — push against a wall or your other foot, no joint movement.
- Scar and swelling management — once the incision is fully sealed.
- Protected weight-bearing in a boot often starts here in appropriate cases.[6]
Where caution applies: trimalleolar fractures, posterior malleolar involvement, syndesmotic screws, osteoporotic bone, and medically high-risk patients. Follow your surgeon's specific instructions over any general timeline.
PHASE 3 — WEEKS 6 TO 12: WEIGHT, STRENGTH, AND BALANCE
The real work. This is where formal PT earns its place if you're going to use it.
- Progress to full weight-bearing and wean out of the boot into a shoe.
- Gait retraining — most patients develop a limp during immobilization and keep it unless it's actively corrected.
- Dorsiflexion stretching — a knee-to-wall stretch. This is the motion that determines whether stairs feel normal.
- Calf raises — double-leg first, then progressively toward single-leg. The calf is the single most important muscle to rebuild.
- Balance work — single-leg standing, eyes open, then eyes closed, then on an unstable surface.
- Stationary cycling and pool walking — load without impact.
PHASE 4 — MONTHS 3 TO 6: LOADING AND RETURN TO ACTIVITY
- Single-leg heel raise for reps — this is my gatekeeper test.
- Impact progression — walk-jog intervals before continuous running.
- Lateral and rotational movement — cutting, pivoting, change of direction.
- Sport-specific drills before returning to sport.
PHASE 5 — MONTHS 6 TO 12: THE LONG TAIL
Improvement continues well past the point most people expect. Swelling at the end of a long day can persist for a year and is not a sign something is wrong.
───────────────────────────────────────
THE FOUR TESTS I USE BEFORE CLEARING SOMEONE
Dates don't clear patients. These do.
1. Symmetric dorsiflexion. Knee-to-wall distance within about 2 cm of the other side.
2. Single-leg heel raises. Approaching the number you can do on the uninjured side. Most patients are shocked at the gap.
3. Single-leg balance. 30 seconds, eyes closed, without grabbing anything.
4. Confident single-leg hop. Symmetric distance, and a controlled landing.
Fail any of these and you're not ready for pickleball, no matter what week it is.
───────────────────────────────────────
RETURN TO SPORT — REALISTIC GUIDES
These assume uncomplicated healing and passed testing:
Activity | Typical earliest return |
Stationary cycling, swimming | 6–10 weeks |
Golf | 3–4 months |
Running | 4–6 months |
Pickleball, tennis | 5–8 months |
Basketball, soccer, volleyball | 6–9 months |
CrossFit, gymnastics, dance | 6–12 months |
Roughly 70% of athletes with unstable ankle fractures return without limitations. Bimalleolar and trimalleolar patterns, an associated dislocation, and an associated cartilage injury are the factors linked to worse outcomes.
That last one is the most common reason an ankle still hurts after the bone has healed perfectly and rehab has been done correctly: Ankle Cartilage Injury (Osteochondral Lesion of the Talus)
───────────────────────────────────────
DO YOU ACTUALLY NEED FORMAL PT? MY HONEST ANSWER
Given the trial data, here's how I decide.
Formal PT is most valuable if you:
- Had a trimalleolar fracture, a fracture-dislocation, or syndesmotic fixation
- Are older, live alone, or use a walker — falls risk is the real concern
- Have significant stiffness at the 6-week mark
- Are an athlete returning to cutting or pivoting sport
- Have a physically demanding job with return-to-work requirements
- Are not confident doing exercises on your own — this is the biggest one
A structured home program with clear instruction may be enough if you:
- Had a straightforward, well-fixed fracture
- Are younger and previously active
- Are progressing well at your 6-week visit
- Are reliable about doing the exercises
The trial evidence supports this middle path. But note the certainty caveat above — this is very low certainty evidence, and it should inform the decision rather than dictate it.[4]
───────────────────────────────────────
COMMON MISTAKES IN REHAB
- Waiting for the 6-week visit to start moving anything. Toe motion, knee motion, and hip motion start day one.
- Doing nothing between PT sessions. Two visits a week accomplishes very little without daily home work. This may be part of why supervised programs haven't outperformed good advice.[3][4]
- Skipping calf strengthening. It's tedious, it's the most important thing you'll do, and it's the most commonly neglected.
- Neglecting balance training. Strength without proprioception is how people re-injure themselves.
- Chasing pain-free. Some discomfort with stretching and loading is expected. Sharp pain, swelling that lasts into the next day, or new instability is not.
- Self-advancing weight-bearing. Particularly with syndesmotic screws, osteoporotic bone, or neuropathy.
- Stopping at "I can walk." Walking is the floor, not the goal. Stairs, uneven ground, and single-leg control come later and require deliberate work.
───────────────────────────────────────
DIABETES: THE EXCEPTION THAT CHANGES EVERYTHING
If you have diabetes, the early-motion and early-weight-bearing evidence above does not automatically apply to you.
Diabetes — especially uncontrolled diabetes — raises wound healing and infection risk substantially, and patients with diabetes generally require extended protected weight-bearing after ankle fracture, whether treated operatively or not.
Peripheral neuropathy compounds this, because you may not feel a problem developing. Never self-advance your rehab based on comfort. In one published protocol for this population, patients were casted and non-weight-bearing for the first 4 weeks with passive and active motion, progressing to full weight-bearing and proprioception training between weeks 4 and 8, and advanced strengthening from weeks 8 to 12 — a deliberately slower curve.[7]
───────────────────────────────────────
WHEN TO CALL — RED FLAGS DURING REHAB
- Fever, spreading redness, or wound drainage — possible infection
- Calf pain, swelling, or tenderness — possible blood clot
- New shortness of breath or chest pain — call 911
- Sudden increase in pain after things had been improving
- A pop, giving way, or new instability
- Numbness or a cold foot
───────────────────────────────────────
WHEN TO GET A SECOND OPINION
- You're 3+ months out and dorsiflexion is still severely limited
- The bone healed but the ankle catches, clicks, or hurts deep inside the joint
- You were never given any exercise instruction after your boot came off
- Your ankle feels unstable despite completing rehab
- You've plateaued and nobody has re-imaged the joint
- You have diabetes and are unclear on your restrictions
───────────────────────────────────────
THE BOTTOM LINE
- Active exercise beats immobilization, accelerating return to work by roughly 21 days with no increase in complications.[1]
- Range of motion starting within the first week after ORIF is safe — no increase in complications or reoperations in a 299-patient analysis including bi- and trimalleolar fractures.[2]
- A structured home exercise program with weekly advice beat casting at 12 and 24 weeks in the EMADE trial, converging by 52 weeks.[5]
- Early weight-bearing dramatically reduced PT needs — 85% needed fewer than 8 sessions vs. 11.5%.[6]
- Supervised PT has not clearly outperformed structured advice for the average patient — though this evidence is very low certainty and should not be read as PT being useless.[3][4]
- What you do daily at home matters more than how often you see a therapist.
- Calf strength, dorsiflexion, and single-leg balance are the three things to chase.
- Diabetes changes the timeline. Slower, more protected, more supervised.[7]
