Brostrom Procedure: Ankle Ligament Repair | Dr. Tom Biernacki

The Brostrom Procedure — Repairing Chronic Ankle Instability

What Is the Brostrom Procedure?

Surgical repair of the lateral ankle ligaments — primarily the anterior talofibular ligament (ATFL) — when they’ve become permanently stretched or torn from repeated ankle sprains. Surgeon makes a small incision on the outside of the ankle, identifies damaged ligaments, removes scar tissue, and tightens the ligament to the fibula bone using small anchor screws. Most modifications include the Gould augmentation (extensor retinaculum reinforcement). Outpatient, 45-90 minutes.

Who Needs the Brostrom Procedure?

You may be a candidate if you have ALL of: chronic lateral ankle instability (3+ sprains), failed 6+ months of conservative treatment, stress radiographic instability, MRI confirmation of attenuated/torn ATFL, and active lifestyle goals.

Brostrom Recovery Timeline

Day of surgery: Outpatient, splint applied.
Week 1: Splint, non-weightbearing on crutches/scooter, elevation 80%.
Week 2: Sutures out, transition to walking boot.
Weeks 3-4: Boot, full weight-bearing. Begin PT.
Weeks 5-6: Boot off, lace-up brace.
Weeks 7-12: Brace for sport drills, stationary bike, jogging.
Months 4-6: Sport-specific return-to-play, final clearance.

Brostrom Success Rates

85-95% return to pre-injury activity. 80-92% return to competitive sport. 5-10% failure rate. 1-3% complication rate. Outcomes improved by: younger age, single primary procedure, PT compliance, normal hindfoot alignment, BMI under 30, non-smoker.

Brostrom Cost

Self-pay: $7,500-$15,000.
Insured: $1,500-$5,000 out-of-pocket.
Insurance: Almost always covered when conservative care has failed and instability is documented. We obtain pre-authorization.

Frequently Asked Questions

How long am I out of work after Brostrom?

Desk work: 1-2 weeks. Standing job: 6-8 weeks. Heavy labor: 12-16 weeks.

Will my ankle be normal after Brostrom?

Most patients (85-95%) report a near-normal ankle by 6-12 months. High-cutting sports usually require functional bracing for 12 months.

Can I have Brostrom on both ankles?

Yes, but never at the same time. Recover from one (4-6 months) before scheduling the other.

Is Brostrom done arthroscopically?

Increasingly yes. All-arthroscopic Brostrom has gained popularity. We offer both arthroscopic and mini-open techniques.

What if I already had a Brostrom and it failed?

Revision options include re-do Brostrom (rare) or anatomic tendon graft reconstruction (most common revision approach).

Can I avoid Brostrom by wearing an ankle brace forever?

Yes, if the brace adequately controls instability. Many patients prefer surgery to avoid lifelong bracing.

Will Brostrom prevent ankle arthritis?

Possibly yes. Repeated sprains cause cartilage damage that leads to arthritis. Stabilizing early may slow progression.

Is Brostrom covered by insurance?

Almost always yes when conservative treatment has failed and instability is documented.

Frequently Asked Questions

When should I see a podiatrist?

If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).

What does treatment cost?

Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.

How quickly can I get an appointment?

Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.

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.
