Rehab after a Brostrom procedure, which tightens and reattaches the ligaments on the outside of the ankle, typically moves from two weeks without weight on the foot, to walking in a boot, to a shoe with an ankle brace around two months, and toward sport from about three to six months. Throughout, the ankle is kept from rolling inward (inversion) until the repair is strong. If you live in Hamilton County, the matching team can suggest an independent, licensed therapist in the network who sees people one-on-one in private suites off the Monon Trail in Carmel.

- No weight on the foot
- Often the first 2 weeks
- Walking in a boot
- Commonly weeks 3 to 6
- Shoe and brace
- Around weeks 7 to 8 in many protocols
- Toward sport
- Roughly 3 to 6 months, by testing

Why is rolling the foot inward off limits after a Brostrom repair?
Turning the sole inward, called inversion, stretches exactly the ligaments the surgeon tightened, so early protocols forbid it until the tissue has healed enough to resist it. Many also avoid pointing the toes down hard in the first weeks, because that position adds tension to the front ligament on the outside of the ankle.
The Mass General Brigham protocol for this operation, for example, avoids inversion and plantarflexion in the first two weeks and keeps inversion only to neutral through the first six. Your surgeon may be stricter, particularly if the repair was augmented with suture tape, a tendon was repaired at the same time, or you have naturally loose joints.
What are the phases after Brostrom surgery, week by week?
The Mass General Brigham protocol moves through six phases, combining time since surgery with criteria such as a normal walk and balance scores. The table follows that published hospital protocol; yours may differ.
| Weeks after surgery | Main goals | Typical milestones |
|---|---|---|
| 0 to 2 | Protect the repair, control swelling, keep the hip and thigh strong | Crutches with no weight on the foot; quad sets and straight-leg raises |
| 3 to 6 | Walk in the boot, restore up-and-down ankle motion | Weight as tolerated in the boot; gentle isometrics except inversion |
| 7 to 8 | Shoe with an ankle brace, normal walking, early strength | Calf raises, band work, bike, single-leg balance progressions |
| 9 to 12 | Full motion, stronger calf, harder balance | About 25 single-leg heel raises; reach-test scores close to the other side |
| 3 to 4 months | Early return to sport movements | No swelling after a 30-minute brisk walk; hop tests near the other leg |
| 5 to 6 months and beyond | Unrestricted sport | A return-to-running program, then agility and plyometrics, then sport-specific drills |
What does the ankle surgeon’s protocol decide?
The surgeon decides how long you stay off the foot, when the boot becomes a brace, when inversion may be stretched or strengthened, and when running and sport can begin. Those depend on whether the ligament was repaired with your own tissue, reinforced with tape or reconstructed with a graft.
Your therapist decides how to reach the goals in each phase and confirms the criteria have been met: a walk without a limp, equal motion, single-leg heel raises, balance and hop scores. If your ankle is stiffer or looser than the protocol expects, the therapist raises it with the surgeon’s office rather than pushing through.
Why is balance training the heart of Brostrom rehab?
Balance work matters because repeated sprains damage the nerve endings in the ligaments that tell the brain where the foot is, and surgery tightens the ligament but does not restore that sense on its own. Retraining it is what helps the ankle react quickly on uneven ground.
Expect progressions from standing on one leg to wobble boards, catching a ball while balancing, reach tests in several directions and finally hopping and cutting. The indoor turf corridor outside the suites gives room for that last stage in winter, when the Monon Trail and Grand Park fields are icy. The ankle that keeps giving way page explains why the sense of instability develops in the first place.
What strength does the calf and hip need before running after a Brostrom?
Before running, most protocols want the operated ankle to match the other side for motion and to manage a long set of single-leg heel raises, with the hip and thigh strong enough to keep the knee steady on landing. The Mass General Brigham protocol uses 25 single-leg heel raises and reach-test scores within about 90 percent of the other leg as criteria in the transitional phase.
The outside-of-the-ankle muscles, the peroneals, also need specific work, because they are the active guard against the foot rolling under you. Once inversion is allowed, banded eversion and inversion, lateral hops and side shuffles join the plan. Hip strength gets attention too: a weak outer hip lets the whole leg sway, which loads the ankle at the worst moment. A therapist measures these rather than estimating them by eye.
- Single-leg heel raises, building toward around 25 in a row
- Banded eversion, then inversion once your surgeon allows it
- Side-lying and standing hip work such as the clamshell and band walks
- Balance reach tests compared with the other leg
Is there anything to do before a Brostrom procedure?
Yes: arriving with a strong calf and hip and a good grasp of crutch walking makes the non-weight-bearing weeks easier. Because most people having this surgery have already tried a course of rehab for chronic ankle instability, the exercises will often be familiar.
Plan for two weeks with no weight on the foot. A right-ankle repair rules out driving for a while, so arrange rides, and consider a knee scooter if your surgeon approves one.
How do I book Brostrom rehab near Carmel?
Complete the physical therapy questionnaire, choose after surgery and give the date of the repair and your sport or job. A person on the matching team proposes an independent therapist in the network, and that therapist’s office confirms benefits and books.
Suites run from 5 AM on weekdays and 7 AM to 4 PM on weekends, which helps athletes fit sessions around school or work. For the final step, return to sport testing describes the hop and agility measurements used before clearance.
Call your surgeon after ankle ligament surgery if
- Calf pain, swelling or warmth above the splint or boot
- Chest pain or shortness of breath: call 911
- Fever, or an incision that is red, hot or leaking
- Toes that turn pale, blue or numb and do not recover when elevated
- A new twist or roll of the ankle with a pop or sudden swelling
If you think it is an emergency, call 911.
