| Ligament | Function | Injury Rate | Clinical Test | Surgical Role |
|---|---|---|---|---|
| ATFL (Anterior Talofibular) | Resists anterior talar translation; primary plantarflexion stabilizer | 70% of ankle sprains | Anterior drawer test | Primary repair target in modified Brostrom |
| CFL (Calcaneofibular) | Resists subtalar inversion; dorsiflexion stabilizer | Torn in 50-75% of ATFL tears | Talar tilt test | Repaired with ATFL in combined instability |
| PTFL (Posterior Talofibular) | Resists posterior talar translation; very strong | Rarely torn (less than 10%) | Posterior drawer test | Not typically addressed |
| Treatment | Indication | Success Rate | Return to Sport | Notes |
|---|---|---|---|---|
| Functional PT (peroneal + proprioception) | First-episode instability; first-line | 85% return to sport without instability | 4-8 weeks | Peroneal strengthening + proprioception training; balance board |
| Lace-Up / Semi-Rigid Brace | Recurrent sprains; in-season athlete | Reduces re-sprain risk 50-70% | Immediate with brace | Prophylactic for high-risk sport return |

Chronic ankle instability — that feeling that your ankle keeps giving way — usually starts after one bad sprain that did not fully heal. The right combination of bracing, balance training, and sometimes surgery restores stability.
You’re in the right place. Dr. Tom Biernacki, DPM, FACFAS — board-certified foot & ankle surgeon with 3,000+ surgeries — explains exactly what chronic ankle instability means and what works. Call (810) 206-1402 for same-day appointment at Howell or Bloomfield Hills.

The most important clinical decision with Chronic Ankle Instability Treatment Surgery Michigan isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
What Is Chronic Ankle Instability?
Chronic lateral ankle instability is a condition characterized by persistent mechanical looseness of the lateral (outer) ankle ligaments following one or more ankle sprains. Patients describe a feeling of the ankle “giving way” — particularly during athletic activity, walking on uneven ground, or making quick directional changes. Repeated ankle sprains, chronic pain and swelling, and functional limitations that persist months after the original injury are the hallmarks of this condition.
Chronic instability affects an estimated 20–40% of patients who sustain acute lateral ankle sprains. The three ligaments of the lateral ankle complex — the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL) — are injured to varying degrees with ankle sprains. When they heal in a lengthened, lax position rather than at their normal tension, the biomechanical constraints on ankle motion are lost. The foot can roll inward beyond normal limits, creating the characteristic instability and predisposing to subsequent sprains.
Mechanical vs. Functional Instability
An important distinction shapes the treatment approach: mechanical instability (objective laxity of the ligaments demonstrable on examination and imaging) versus functional instability (the subjective feeling of giving way despite normal ligament integrity). Most patients with chronic ankle instability have components of both.
Mechanical instability is confirmed by the anterior drawer test (translating the talus forward relative to the tibia) and talar tilt test. Stress X-rays quantify the degree of laxity. MRI evaluates ligament integrity, associated cartilage damage (osteochondral lesions), and concomitant peroneal tendon pathology. Functional instability, even without significant mechanical laxity, responds well to physical therapy and proprioception training.
Conservative Treatment: Physical Therapy and Bracing
Conservative management is the first-line approach for chronic ankle instability, and achieves satisfactory results in 60–80% of patients when implemented rigorously. Physical therapy is the cornerstone, specifically targeting the deficits that develop following ankle sprains: peroneal muscle weakness, impaired proprioception (the body’s sense of ankle position), and neuromuscular coordination deficits.
Peroneal (fibularis) muscle strengthening — the muscles that actively evert (roll outward) the ankle — is the most critical component. These muscles serve as the dynamic stabilizers of the lateral ankle, and their strength and reaction time are diminished after injury. Resistance band exercises, single-leg stance on unstable surfaces, and sport-specific agility training progressively restore peroneal function. Balance and proprioception training on wobble boards, BOSU balls, and single-leg surfaces retrains the ankle’s positional sense — which is impaired even after apparent ligament healing due to mechanoreceptor damage in the injured ligaments.
Ankle bracing provides external mechanical support during activity while rehabilitation progresses. Lace-up ankle braces are more effective than simple sleeve-type supports for instability, as they provide proprioceptive feedback and restrict excessive inversion. Custom ankle-foot orthoses (AFOs) are prescribed for severe instability or when standard bracing is insufficient. Custom orthotics with a lateral heel wedge correct the hindfoot varus alignment common in chronically unstable ankles.
Surgical Treatment: The Broström-Gould Procedure
When conservative management fails to provide adequate stability and quality of life — typically after 3–6 months of dedicated physical therapy and bracing — lateral ankle ligament reconstruction is indicated. The modified Broström-Gould procedure is the gold standard surgical approach and is the most commonly performed ankle ligament reconstruction in the world.
The procedure involves identification and imbrication (tightening/shortening) of the ATFL and CFL, which are retensioned to their anatomic length and sutured to bone using anchors. The inferior extensor retinaculum is then reinforced over the repair (the “Gould modification”), adding an additional layer of stabilization and reinforcing proprioceptive tissue. The procedure is performed under regional or general anesthesia as an outpatient surgery through a small incision over the lateral ankle.
When the native ligament tissue is severely attenuated (stretched beyond repair) or prior surgeries have compromised local tissue, ligament augmentation with allograft (cadaver tendon) or autograft tissue provides additional structural support. Arthroscopic evaluation of the ankle joint is frequently combined with open ligament reconstruction to address concomitant pathology — particularly osteochondral defects of the talus, which occur in approximately 40–66% of chronic instability cases.
Recovery After Ankle Stabilization Surgery
Post-operative rehabilitation after Broström-Gould repair follows a structured protocol. Immediately after surgery, the ankle is immobilized in a splint or boot for 1–2 weeks of wound healing. Progressive weightbearing begins at 2–3 weeks with a walking boot. Physical therapy commences at 3–6 weeks, focusing on range-of-motion, swelling management, and peroneal activation. Strengthening progresses at 6–12 weeks. Return to jogging is typically at 3–4 months, cutting and sport-specific activities at 4–5 months, and full competitive sport clearance at 5–6 months.
Outcomes are excellent: 85–95% of patients report good to excellent results, with significant reduction in giving-way episodes, restoration of confidence on uneven terrain, and return to full pre-injury activity levels. Re-instability requiring revision surgery occurs in fewer than 10% of cases.
When to See Dr. Biernacki for Ankle Instability
If you experience repeated ankle sprains (more than 2 in the past year), a persistent feeling of the ankle giving way during activity, chronic ankle pain or swelling that has not resolved after adequate recovery from a prior sprain, or difficulty returning to sport due to ankle insecurity — it is time for a formal evaluation. At Balance Foot & Ankle, Dr. Biernacki performs a comprehensive mechanical and functional assessment, orders appropriate imaging, and provides a clear, staged treatment plan from conservative through surgical options.

Dr. Tom Biernacki’s Recommendation
Chronic ankle instability is one of the most treatable conditions I see — once we identify it. The problem is that patients often accept repeated ankle sprains as ‘just bad luck’ or blame their ‘weak ankles’ without realizing there’s a fixable structural problem. I love telling a patient who’s been spraining their ankle four times a year that we can likely eliminate that pattern entirely — either with intensive therapy and bracing, or with a straightforward outpatient surgery. You don’t have to keep spraining the same ankle.
— Dr. Tom Biernacki, DPM | Board-Certified Podiatric Surgeon | Balance Foot & Ankle
Frequently Asked Questions
How do I know if I have chronic ankle instability?
Common signs include: repeated ankle sprains (more than 2 in the past year), a persistent feeling that the ankle ‘gives way’ during activity, difficulty walking on uneven ground without fear of rolling the ankle, and chronic ankle pain, stiffness, or swelling. Clinical examination and stress testing by Dr. Biernacki confirm the diagnosis.
Can ankle instability be fixed without surgery?
Yes — many cases of chronic ankle instability are successfully managed with physical therapy focusing on peroneal strengthening and proprioception training, combined with ankle bracing and custom orthotics. Approximately 60–80% of patients achieve satisfactory stability with dedicated conservative management. Surgery is reserved for cases that fail 3–6 months of conservative treatment.
What is the Broström procedure for ankle instability?
The modified Broström-Gould procedure is the gold-standard surgical repair for chronic lateral ankle instability. It involves shortening and reattaching the stretched ATFL and CFL ligaments to bone anchors, restoring their normal tension. The Gould modification reinforces the repair with the inferior extensor retinaculum. It is an outpatient procedure with 85–95% good to excellent outcomes.
How long is recovery after ankle stabilization surgery?
Post-operative recovery involves 1–2 weeks of immobilization, progressive weightbearing at 2–3 weeks, physical therapy from 3–6 weeks, return to jogging at 3–4 months, and full return to sport at 5–6 months. The timeline is similar for most patients regardless of sport level, though high-demand athletes may take slightly longer.
Does ankle instability worsen with age?
Untreated chronic ankle instability can progress over time. Repeated sprains cause cumulative damage to cartilage, resulting in osteochondral lesions and, eventually, ankle arthritis. Peroneal tendon degeneration from recurrent inversion loading is also common. Early intervention — conservative or surgical — prevents these secondary complications.

How long does treatment take to work?
Most patients see improvement in 4-8 weeks with consistent conservative care. Persistent symptoms after 8 weeks need imaging and escalation.
When is surgery needed?
Surgery is reserved for cases that fail 3-6 months of conservative care, structural deformities, or fractures requiring stabilization.
Is this covered by insurance?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Custom orthotics often require diabetic or post-surgical justification.
