BROSTROM REPAIR: REHABILITATION PROTOCOL
FOR CHRONIC ANKLE INSTABILITY
General Considerations:
• Time frames mentioned in this article should be considered approximate with actual
progression based upon clinical presentation. Careful observation and ongoing
assessments will dictate progress. - No passive inversion or forceful eversion for 6
weeks.
• Avoid plantar flexion greater than resting position for 4 weeks.
• Carefully monitor the incisions and surrounding structures for mobility and signs of
scar tissue formation. Regular soft tissue treatments (i.e. scar mobilization) to
decrease fibrosis.
• No running, jumping, or ballistic activities for 3 months.
• Aerobic and general conditioning throughout rehabilitation process.
• M.D. appointments at day 1, day 8-10, 1 month, 2 months, 4 months, 6 months, and
1 year post-operatively.
0 – 3 Weeks:
• 90° immobilizer for 3 weeks. - Nonweightbearing for 3 weeks--no push off or
toe-touch walking.
• Progress from posterior splint to pneumatic walker once most of swelling is gone.
• Pain and edema control / modalities as needed (i.e. cryotherapy, electrical stim, soft
tissue treatments).
• Toe curls, toe spreads / extension, gentle foot movements in boot, hip and knee
strengthening exercises.
• Well-leg cycling (bilateral once in walker with light resistance), weight training, and
swimming in posterior splint after 10-12 days post-op.
3 – 6 Weeks:
• Progress to full weight bearing in walking boot. Walking boot weight bearing for 3-6
weeks post-op. Aircast splint for day-to-day activities for 6-12 weeks post-op. -
Immobilizer for sleeping for 4weeks, then Aircast splint for 4-6 weeks.
• Isometrics in multiple planes and progress to active exercises in protected ranges.
• Proprioception exercises, intrinsic muscle strengthening, manual resisted exercises.
• Soft tissue treatments daily and regular mobilization of intermetatarsal and midtarsal
joints. Cautious with talocrural and subtalar mobilization.
• Cycling, aerobic machines in splint as tolerated, and pool workouts in splint.
6 – 12 Weeks:
• Gradually increase intensity of exercises focusing on closed-chain and balance /
proprioception. - Passive and active range of motion exercises into inversion and
eversion cautiously.
3 – 6 Months:
• Progress back into athletics based upon functional status. - Wear a lace-up ankle
support for athletics.
