The most important clinical decision with Brostrom Procedure Surgical Repair Chronic Ankle Instability isn't which treatment to start with — it's which subtype or underlying cause you actually have. Our podiatrists regularly see patients who've been treated for months for the wrong diagnosis. The correct identification changes the entire treatment path.

Is Surgery the Right Next Step for Your Ankle?

After multiple ankle sprains and months of physical therapy, the question patients ask us most is: “At what point do I actually need surgery?” It’s a fair question — surgery is a significant decision. But for the right patient, the Broström procedure transforms chronic ankle instability from a daily limitation into a solved problem.
In our practice, we consider surgical repair when a patient has documented instability on stress X-rays or MRI, has completed 3–6 months of structured physical therapy without adequate improvement, and is significantly limited in their desired activity level. That’s the threshold — not the number of sprains alone.
Key takeaway: Surgical candidacy is based on function, not just number of sprains. If instability limits your activity despite adequate conservative care, surgery is appropriate regardless of how many sprains you’ve had.
The Original Broström vs. the Broström-Gould Modification
It’s worth understanding the evolution of this procedure because surgeons sometimes use the terms differently:
- Original Broström (1966): Direct imbrication (shortening and overlap) of the ATFL at its fibular attachment. Simple, effective for isolated ATFL insufficiency.
- Broström-Gould (1980): Added reinforcement of the ATFL repair with the inferior extensor retinaculum — a sheet of connective tissue native to the ankle. This augmentation adds mechanical strength and addresses subtalar instability. Now considered the standard of care.
- Broström-Gould + InternalBrace (2010s): Adds a synthetic suture tape construct that provides immediate structural support while the repair heals, enabling faster rehabilitation and higher early loads.
When your surgeon says “Broström procedure,” they almost certainly mean the Broström-Gould modification. The original unmodified Broström is rarely performed today.
Pre-Operative Evaluation
Before scheduling surgery, we complete a thorough pre-operative evaluation to confirm candidacy and plan the procedure:
- Clinical examination: Anterior drawer test and talar tilt test to quantify laxity
- Stress X-rays: Confirm pathologic talar tilt (>10°) or anterior drawer (>10mm)
- MRI: Assess ATFL/CFL quality, identify concomitant pathology (OCD lesions, os trigonum, peroneal tendon tears)
- Gait analysis: Identify hindfoot varus deformity that predisposes to failure if not corrected concurrently
Concurrent pathology found on MRI — particularly osteochondral defects of the talus (present in 25–40% of instability cases) — is addressed arthroscopically at the same surgical session.
What to Expect: Surgery Day
The Broström procedure is performed as an outpatient surgery. Here’s the day-of experience:
- Anesthesia: Regional ankle block (local numbing of the ankle nerves) + IV sedation; rarely requires general anesthesia
- Positioning: Supine with a leg holder to access the lateral ankle
- Tourniquet: Applied to the thigh to reduce bleeding during the procedure
- Operative time: 45–90 minutes for Broström-Gould alone; 90–120 minutes with arthroscopy
- Post-op: Placed in a posterior splint; crutches provided; discharged home same day
- Pain management: Oral anti-inflammatories + acetaminophen; opioids prescribed sparingly for breakthrough pain
Detailed Recovery Protocol
Recovery from the Broström procedure follows a structured progression. Rushing any phase increases the risk of re-injury:
- Phase 1 (0–2 weeks): Non-weight-bearing in splint; ice, elevation, and pain management; wound care
- Phase 2 (2–6 weeks): Progressive weight-bearing in walking boot; passive range-of-motion exercises begin at week 2; sutures removed at 10–14 days
- Phase 3 (6–10 weeks): Transition to supportive shoe; active ROM and strengthening begins; PT 2–3x/week
- Phase 4 (10–16 weeks): Proprioception and balance training; light jogging on flat surfaces; sport-specific conditioning begins
- Phase 5 (4–6 months): Return to sports clearance based on functional testing — hop tests, Y-balance test, sport-specific agility
Key takeaway: Return to sport clearance after Broström repair should be based on functional criteria, not just time. Patients who pass hop tests and Y-balance assessments have significantly lower re-injury rates.
⚠️ Factors that increase risk of poor outcomes:
- Generalized ligamentous hypermobility (consider augmentation)
- Hindfoot varus deformity not corrected at surgery
- Non-compliance with post-operative rehabilitation protocol
- Return to sports before functional clearance criteria are met
- BMI >30 (associated with slower healing and higher complication rates)

Frequently Asked Questions
How long is recovery from Broström surgery?
Full return to unrestricted sports takes 4–6 months for most patients. Return to light daily activities occurs by 6–8 weeks. Return to running typically occurs at 12–16 weeks. Recovery is longer (5–7 months) when arthroscopy is added to address cartilage lesions.
What are the risks of Broström surgery?
Complication rates are low (<5%): wound complications (most common), sural nerve irritation or injury, inadequate correction, infection (rare), deep vein thrombosis (rare). Long-term recurrence of instability occurs in 5–10% of primary repairs at 10 years.
Can I avoid surgery with a better brace?
Functional bracing can control instability adequately for many patients who want to avoid surgery or who have modest activity demands. Lace-up braces (ASO, McDavid) or rigid stirrup braces (Aircast) reduce re-sprain risk by 30–50% in instability patients. However, bracing manages instability — it doesn’t repair the underlying structural deficit. For high-demand athletes or patients unwilling to brace lifelong, surgery is a more definitive solution.
The Bottom Line
The Broström procedure for chronic ankle instability is one of the most reliable orthopedic procedures in the foot and ankle. Well-selected patients achieve 90%+ satisfaction with a clear return-to-sport timeline. If your ankles are holding you back from the activities you love, a consultation with Dr. Biernacki at Balance Foot & Ankle can determine whether surgery is the right step for you.
