Brostrom-Gould Lateral Ankle Ligament Reconstruction: Post-Operative Physiotherapy Protocol

While the vast majority of acute lateral ankle sprains resolve successfully with conservative physiotherapy, approximately ten to twenty percent of patients develop chronic, refractory mechanical instability characterized by permanent pathological ligamentous laxity and recurrent giving-way episodes. When structured non-operative sensorimotor training fails to restore stability over a three- to six-month trial, surgical stabilization is indicated. The Brostrom-Gould procedure represents the global gold-standard anatomical surgical repair for chronic lateral ankle instability. Initially described by Lennart Brostrom and subsequently modified by Gould, the procedure involves direct anatomical repair of the attenuated or torn anterior talofibular ligament and calcaneofibular ligament, augmented by mobilizing and suturing the lateral portion of the inferior extensor retinaculum over the repair site. Post-operative rehabilitation must strictly respect the biological stages of tendon-to-bone and soft-tissue healing to ensure the reconstructed construct matures into a robust, mechanically sound restraint.

Navigating Home Recovery, Crutch Walking, and Indian Household Steps

Post-operative recovery from a Brostrom-Gould reconstruction in Indian domestic environments requires careful environmental adaptation. During the initial two to six weeks of protected immobilization in a non-weight-bearing cast or pneumatic walking boot, patients must navigate domestic life without bearing full weight. Indian domestic architectures frequently feature raised door sills (chaukhat), narrow bathrooms with wet, slippery tile floors, and multi-story staircases without handrails. Hopping on one leg or using crutches across these surfaces carries significant slip risks. Patients must be carefully educated on non-weight-bearing crutch mobility and stair negotiation (up with the good leg, down with the bad leg). Furthermore, family members must assist in rearranging the home environment to eliminate loose rugs and slippery floor hazards, ensuring the surgical site is protected from accidental sudden weight-bearing impacts.

Surgical Anatomy, Retinacular Augmentation, and Suture Anchor Mechanics

The surgical architecture of the Brostrom-Gould repair provides both anatomical restoration and biological reinforcement. The surgeon makes a curved incision over the distal tip of the lateral malleolus, identifying the attenuated remnants of the ATFL and CFL. Suture anchors (titanium or bio-absorbable) are placed into the anterior fibular margin, and the ligament ends are imbricated, shortened, and re-anchored into a pristine anatomical bleeding bone bed to optimize osseous integration. The vital Gould modification involves mobilizing the strong lateral edge of the inferior extensor retinaculum and advancing it proximally to suture it over the repaired ATFL, reinforcing the repair, limiting excessive inversion, and correcting subtalar joint laxity. Biomechanically, the freshly sutured construct relies entirely on the tensile strength of the suture material during the first six weeks; premature active inversion or forced plantarflexion can tear the sutures out of bone anchors, leading to catastrophic surgical failure.

Phased Post-Surgical Protocol: From Immobilisation to Sport Clearance

Rehabilitation following Brostrom-Gould reconstruction follows a structured, four-phase clinical pathway. Phase one (weeks zero to two) enforces strict non-weight-bearing immobilization in a posterior splint or cast, accompanied by elevation to resolve post-operative hemarthrosis. Phase two (weeks two to six) transitions the patient into a removable pneumatic walking boot, permitting protected partial weight-bearing with crutches and initiating active, pain-free sagittal-plane dorsiflexion and plantarflexion, while strictly avoiding all active or passive inversion and eversion. Phase three (weeks six to twelve) weans the patient out of the boot into a supportive lace-up or stirrup ankle brace, progressing to full unassisted weight-bearing, closed-chain calf strengthening, and static balance drills. Phase four (months three to six) introduces dynamic wobble board perturbations, progressive running, lateral agility drills, and sport-specific plyometrics, leading to unrestricted athletic clearance.
