| Test | Ligament Assessed | Positive Finding | Sensitivity / Specificity | Implication |
|---|---|---|---|---|
| Anterior Drawer Test | ATFL | >3mm anterior talar translation vs contralateral; soft end-feel | 74% sensitivity; 78% specificity | ATFL laxity; chronic lateral instability |
| Talar Tilt Test | CFL | >5–10° inversion vs contralateral | 50–60% sensitivity; higher with CFL + ATFL combined | Combined ATFL/CFL insufficiency |
| External Rotation Stress (Cotton) Test | Syndesmosis (ATFL, PTFL, interosseous ligament) | Lateral fibular displacement on mortise view | Moderate; exam under fluoroscopy most accurate | Syndesmotic instability — high ankle sprain |
| Squeeze Test | Syndesmosis / interosseous membrane | Pain at ankle with mid-fibula compression | 30% sensitivity; 94% specificity | High ankle sprain; requires weight-bearing X-ray + MRI |
| Coleman Block Test | Hindfoot / 1st ray flexibility | Varus hindfoot corrects on elevated block | Functional test | Flexible cavovarus driving ankle instability |
| Intervention | Mechanism | Indication | Outcome |
|---|---|---|---|
| Peroneal strengthening (eccentric) | Restores dynamic lateral ankle stabilization | All CAI patients — first-line; post-surgical adjunct | Reduces re-sprain by 50–70%; essential pre/post-op |
| Proprioception / balance training (BAPS) | Restores mechanoreceptor function in ATFL stump | All CAI; especially proprioceptive deficits | Reduces re-sprain; addresses neuromuscular deficit |
| Semi-rigid lace-up brace | Mechanical and proprioceptive stabilization | In-season athletes; all CAI for activity | Reduces re-sprain 50–70%; long-term use acceptable |
| Modified Brostrom + Gould | Anatomic ATFL/CFL repair + extensor retinaculum reinforcement | Failed 3–6 months PT/bracing; Grade II–III laxity | 85–95% good/excellent; 4–6 months return sport |
| Allograft reconstruction (Chrisman-Snook type) | Non-anatomic tenodesis using peroneus brevis / allograft | Failed Brostrom; revision; tissue insufficiency; hypermobility | 75–85% stability; longer recovery; affects eversion strength |
| Calcaneal osteotomy + Brostrom | Corrects varus heel driving recurrent inversion | CAI with cavovarus deformity | Essential when heel varus is driver; Brostrom alone recurs |
Quick answer: Treatment for ankle instability treatment bracing surgery follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

What Is Chronic Ankle Instability?
Chronic ankle instability (CAI) develops when the lateral ankle ligaments — primarily the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) — fail to heal properly after one or more sprains, leaving the ankle mechanically lax and/or functionally unstable. Patients experience repeated giving-way episodes on uneven surfaces, fear of ankle sprains during athletic activity, and persistent weakness and instability that prevent return to previous activity levels.
CAI affects approximately 15-20% of acute ankle sprain patients and is one of the most common reasons young, active individuals see sports medicine physicians and podiatric surgeons.
Conservative Treatment
The cornerstone of conservative management is rehabilitation targeting the two deficits that contribute to instability: peroneal muscle weakness (the peroneal muscles are the primary dynamic lateral stabilizers — if they’re weak, the ligament laxity has no muscular compensation) and proprioceptive deficit (the damaged ligaments have impaired mechanoreceptors, reducing the ankle’s reflexive stability response).
A structured 12-week rehabilitation program combining peroneal strengthening, proprioceptive retraining (balance board, single-leg activities), and neuromuscular training successfully eliminates instability in approximately 50-60% of CAI patients. Those who don’t respond to rehabilitation are surgical candidates.
Functional ankle bracing — lace-up or rigid hinged braces — provides external lateral support during activity and is essential for any return to sport during rehabilitation and for 12 months post-injury. It does not resolve the instability but prevents recurrent sprains while the underlying deficit is being addressed.
Brostrom-Gould Surgical Reconstruction
The Brostrom-Gould procedure is the gold standard surgical treatment for chronic lateral ankle instability. It involves anatomic repair of the ATFL and CFL — the stretched, attenuated ligament tissue is shortened, imbricated, and secured back to its anatomic attachment on the fibula. The inferior extensor retinaculum (Gould modification) is incorporated to reinforce the repair.
The InternalBrace augmentation uses a suture tape device secured with bone anchors to provide immediate mechanical stability alongside the biological repair, allowing earlier and more aggressive rehabilitation with lower re-failure rates than historical repair-only techniques.
Outcomes are excellent — 85-90% of patients return to their previous level of activity with elimination of instability. Return to sport timeline is 4-6 months.
Surgical Recovery
Week 1-2: Non-weight-bearing in splint. Week 2-6: Progressive weight-bearing in boot. Week 6-10: Transition to regular shoe, begin physical therapy. Month 3-4: Jogging protocol. Month 4-6: Return to sport. Full neuromuscular return (confidence on uneven surfaces) continues to improve for 12 months post-surgery.

✅ Pros / Benefits
- Brostrom InternalBrace surgical reconstruction — 4-6 month return to sport, 85-90% success rate
- Comprehensive rehabilitation protocol targeting peroneal strength and proprioception
- Structured conservative trial before surgical recommendation — not all instability needs surgery
❌ Cons / Risks
- Rehabilitation takes 12 weeks with consistent effort — compliance is the limiting factor for conservative success
- Surgical recovery is 4-6 months minimum — significant commitment for active patients
- Underlying predisposing factors (cavus foot, generalized ligament laxity) may increase recurrence risk
Dr. Tom Biernacki’s Recommendation
Ankle instability is one of my most satisfying conditions to treat surgically — the Brostrom with InternalBrace is a reliable procedure with excellent outcomes and a relatively predictable recovery timeline. But I’m always careful to do a proper 12-week rehabilitation trial first, because a meaningful portion of CAI patients can be successfully managed non-surgically if they actually complete the peroneal strengthening and balance training program. The problem is most patients — understandably — stop rehab as soon as their symptoms improve, before the neural and muscular adaptations are fully established. I spend time explaining why the full 12 weeks matter.

Frequently Asked Questions
Will my ankle instability go away without surgery?
Approximately 50-60% of chronic ankle instability patients successfully manage with structured rehabilitation. Those who don’t respond to 6 months of genuine rehabilitation are appropriate surgical candidates.
What is the Brostrom procedure?
An anatomic lateral ligament repair that tightens and secures the stretched ATFL and CFL back to their anatomic fibular attachment. The InternalBrace modification adds a suture tape augment for immediate mechanical support.
How long until I can play sports after ankle instability surgery?
Most patients return to sport at 4-6 months post-Brostrom. Confidence on uneven terrain continues to improve up to 12 months as neuromuscular recovery progresses.
