Chronic lateral ankle instability is one of the most common sequelae of ankle sprains — and one of the most undertreated. When the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) are repeatedly sprained without adequate healing, they become permanently elongated and lose their ability to prevent ankle rolling. Patients develop a chronic giving-way sensation, recurrent sprains with trivial trauma, and ongoing apprehension with athletic activity. For patients who have failed adequate physical therapy and bracing, the Broström procedure offers a definitive, anatomic repair of the lateral ankle ligament complex.
The most important clinical decision with Lateral Ankle Ligament Reconstruction Brostrom Procedure isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
Who Is a Candidate for the Broström Procedure?
The ideal Broström candidate has documented chronic lateral ankle instability with recurrent giving-way, has completed at least 3–6 months of structured physical therapy (peroneal strengthening, proprioception, neuromuscular training) without adequate improvement, and demonstrates objective instability on examination or stress X-rays. MRI is performed to confirm ATFL and CFL status and rule out concurrent pathology (osteochondral lesions, peroneal tendon tears) that may require simultaneous treatment. Patients with severe hyperlaxity (generalized joint hypermobility) or revision cases may require a tenodesis augmentation rather than the anatomic repair.
The Broström Procedure: What Happens
The procedure is typically performed as an outpatient surgery under general or regional anesthesia. A 4–5cm incision is made along the anterior lateral ankle. The ATFL (and CFL if needed) are identified and released from their fibular origin. The ligaments are imbricated (tightened and overlapped) and reattached to the fibula with suture anchors — restoring their anatomic tension and length. The Gould modification — augmenting the repair with a flap of the inferior extensor retinaculum sutured over the repaired ligaments — provides additional strength and is used in most cases. If concurrent pathology is present (osteochondral lesion, loose bodies), it is addressed arthroscopically at the same setting.
Recovery Timeline
Recovery from the Broström procedure follows a structured progression. Weeks 1–2: non-weight-bearing in a splint/cast, elevation. Weeks 3–6: progressive weight bearing in a boot. Weeks 6–10: walking shoe, begin physical therapy (ROM, gentle strengthening). Weeks 10–16: progressive strengthening, proprioception, jogging. Months 4–6: sport-specific training, return to full sport with ankle brace. Most recreational athletes return to sport at 4–5 months; high-level athletes may require 5–6 months for complete recovery and confidence in the repaired ankle.
Outcomes and Long-Term Results
The Broström-Gould procedure has excellent long-term outcomes in the literature. Systematic reviews report good-to-excellent results in 85–95% of patients. Recurrence rates for instability are low — particularly in normal body weight patients without hyperlaxity. Most patients report significant improvement in subjective instability, confidence during athletic activity, and ankle-related quality of life. The anatomic repair preserves the natural ligament biology, unlike tenodesis procedures that sacrifice normal anatomy.
Dr. Tom's Product Recommendations

Ossur Formfit Ankle Walker Boot
⭐ Highly Rated
Walking boot for early post-Broström procedure recovery — provides immobilization during the critical initial ligament healing phase.
Dr. Tom says: “After Broström surgery, patients transition from a splint to a walking boot around weeks 3–4. A comfortable, well-fitting walking boot that can be adjusted as swelling decreases makes the recovery phase significantly more manageable.”
Post-Broström procedure recovery, ligament repair immobilization phase
Return to sport phase (ankle brace worn instead)

Med Spec ASO Ankle Stabilizer
⭐ Highly Rated
Lace-up ankle brace for the return-to-sport phase after Broström procedure — provides external lateral support while the repaired ligaments reach full strength.
Dr. Tom says: “I recommend all Broström patients wear an ankle brace during athletic activity for at least the first year after surgery. The Med Spec ASO is low-profile, fits in athletic footwear, and provides the right amount of lateral support to protect the repaired ligament.”
Post-Broström return to sport, ankle protection during athletics, ongoing instability prevention
Very early post-operative phase (walking boot required instead)

Dr. Tom Biernacki’s Recommendation
The Broström procedure is one of my favorite surgeries because it works so well and the patients come back transformed. Someone who’s been rolling their ankle six times a year, avoiding hiking and basketball and volleyball — after recovery they’re back to everything and feel completely confident in their ankle. The key is selecting the right patient: adequate physical therapy tried first, documented instability, no severe hyperlaxity. When those boxes are checked, the Broström rarely disappoints.

Frequently Asked Questions
How do I know if I need the Broström procedure?
If you’ve had recurrent ankle sprains, a giving-way sensation with normal activities, and you’ve completed 3–6 months of physical therapy without adequate improvement, you may be a Broström candidate. A foot and ankle specialist evaluation including stress X-rays and MRI confirms the diagnosis.
Is the Broström procedure the same as ankle ligament repair?
Yes — the Broström procedure is the anatomic lateral ankle ligament repair, the most commonly performed ankle stabilization surgery. The Gould modification adds extensor retinaculum augmentation.
How long is recovery from Broström surgery?
Most patients return to sport at 4–6 months. Walking independently starts around 3–4 weeks post-op. Physical therapy begins at 6 weeks and runs for 3–4 months.
Can the Broström procedure fail?
Recurrence rates are low (approximately 5–10%). Risk factors for failure include severe generalized hyperlaxity, high BMI, and return to high-demand sport too early without adequate rehabilitation.
Is Broström surgery done arthroscopically?
Traditionally, the Broström is an open procedure. Arthroscopic-assisted techniques exist and are growing in use, but the open Gould-modified Broström remains the gold standard at most centers.
