Quick answer: The Broström procedure repairs and tightens the stretched ATFL and CFL ligaments that cause chronic ankle giving-way. 85–90% of patients achieve good to excellent results with return to full sport at 5–6 months.
What Is the Broström Procedure?
If you’ve been dealing with an ankle that repeatedly gives way — giving you that sickening, uncontrolled inward roll during sport or even daily activities — despite a full rehabilitation program, the Broström procedure is likely the solution you’ve been looking for. It’s the gold standard surgical treatment for chronic lateral ankle instability, with outstanding outcomes and a reliable return-to-sport track record.
Chronic lateral ankle instability develops when the anterior talofibular ligament (ATFL) and/or calcaneofibular ligament (CFL) fail to heal properly after one or more significant sprains. Instead of repairing to normal length and strength, the ligaments heal in an elongated, lax state — allowing the talus to shift abnormally in the mortise. No amount of peroneal strengthening fully compensates for this structural deficit.
Key takeaway: The Broström procedure directly repairs the stretched, incompetent ATFL and CFL — shortening and reinforcing them to restore mechanical stability. It’s not just strengthening; it addresses the structural cause of instability that rehabilitation cannot fix.
The Modified Broström-Gould Procedure
The modern standard is the Broström-Gould modification, which adds reinforcement of the ligament repair using the inferior extensor retinaculum — a strong tissue band on the front of the ankle. This augmentation reduces stress on the repair and lowers re-rupture risk. More recently, the InternalBrace (Arthrex) technique adds a high-strength FiberTape suture anchor construct to provide internal splinting during healing — allowing earlier weight-bearing and potentially better outcomes in active patients.
Surgical Technique Overview
Performed under ankle block anesthesia as an outpatient procedure. A 3–4cm incision is made over the anterolateral ankle. The ATFL is identified and imbricated (folded over itself to shorten and tighten). The CFL may be repaired if it was also torn. The extensor retinaculum is advanced over the repair for reinforcement. If InternalBrace is used, a suture anchor is placed in the fibula and talus with FiberTape connecting them. Total operative time: 45–60 minutes.
Recovery Timeline
Week 0–2: Splint, non-weight-bearing, elevation. Wound healing. Weeks 2–4: Transition to walking boot, progressive weight-bearing. Weeks 4–8: Range of motion and peroneal strengthening begins. Weeks 8–12: Proprioception training, balance board, agility drills. Months 3–5: Sport-specific training, jogging, cutting. Month 5–6: Return to full sport.
InternalBrace technique allows protected weight-bearing sooner (Week 2 vs. Week 4) and may shorten the overall rehabilitation by 2–4 weeks.
Key takeaway: Return to sport after Broström typically occurs at 5–6 months. Athletes who rush the proprioception and sport-specific phases have higher re-injury rates even after anatomically successful repair — full rehabilitation is as important as the surgery itself.
Outcomes and Success Rates
The Broström-Gould procedure has an excellent evidence base accumulated over 50+ years. Published success rates: 85–90% good or excellent outcomes at 10-year follow-up. Return to sport at pre-injury level: approximately 85% at 6 months. Re-rupture rate with the standard technique: 5–10%; with InternalBrace augmentation: reported lower in early studies. Patient satisfaction is high — most patients describe a qualitative improvement in ankle confidence that profoundly changes how they move.
⚠️ Consider Broström evaluation if:
- Ankle gives way with sport, cutting, or uneven terrain despite 3+ months of rehab
- Stress X-rays or MRI confirm ATFL/CFL laxity or incompetence
- You’ve had 3 or more ‘ankle sprains’ in the same ankle
- The ankle gives way during daily activities — not just sport
- Peroneal strengthening has improved strength but not the instability
Broström vs. Non-Anatomic Reconstructions
The Broström-Gould procedure repairs the patient’s native ligaments in their anatomic position — preserving normal joint mechanics and full range of motion. Non-anatomic reconstructions (Watson-Jones, Evans procedures) use tendon grafts rerouted around the fibula — they provide stability but sacrifice subtalar motion and have higher complication rates. Anatomic reconstruction is the current standard and is preferred in virtually all primary cases.
Frequently Asked Questions
Can the Broström procedure be done arthroscopically?
Yes — arthroscopic Broström techniques exist and offer smaller incisions and faster recovery. They are technically demanding and best suited for isolated ATFL repairs without significant CFL involvement. Open technique remains the gold standard for complex cases.
What happens if the Broström fails?
Revision surgery uses allograft or autograft tendon to replace (not just repair) the incompetent ligaments. Outcomes for revision are good but not as predictable as primary repair, which is why getting the primary surgery right — with proper patient selection and technique — matters significantly.
Do I need to stop sports permanently after Broström repair?
No — return to full sport at prior level is the expected outcome for most patients. The ankle is typically more stable post-Broström than it was before the instability began.
The Bottom Line
The Broström procedure is the most reliable, evidence-backed surgery for chronic lateral ankle instability, with decades of outcomes data supporting 85–90% success rates. When conservative rehabilitation has failed to address mechanical giving-way, it corrects the structural cause directly. At Balance Foot & Ankle in Howell and Bloomfield Hills, Michigan, Dr. Biernacki performs Broström and InternalBrace procedures routinely as part of a comprehensive ankle instability program.

What is Foot pain?
Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
