Understanding Chronic Ankle Instability

Ankle sprains are among the most common musculoskeletal injuries — approximately 2 million occur annually in the United States. While most acute sprains heal uneventfully with conservative care, an estimated 20–40% of patients develop persistent symptoms including recurrent sprains, feelings of giving way, chronic swelling, and apprehension during activity. This constellation of symptoms defines chronic ankle instability (CAI).

CAI is not simply “weak ankles.” It represents a structural and neuromuscular failure — the lateral ligaments have healed in an elongated position (lax) and the proprioceptive feedback system that normally prevents the ankle from rolling has been disrupted. Without addressing both mechanical laxity and neuromuscular deficits, the ankle remains vulnerable to repeated injury.

Anatomy: The Lateral Ankle Ligament Complex

The lateral ankle is stabilized by three ligaments:

• Anterior talofibular ligament (ATFL) — the most frequently injured ligament in the ankle, torn in nearly all significant lateral sprains. Runs from the front of the fibula to the front of the talus. Primary restraint against ankle inversion.
• Calcaneofibular ligament (CFL) — connects the fibula to the calcaneus. Torn in moderate-to-severe sprains, providing secondary lateral stability. Must be addressed in surgery when lax.
• Posterior talofibular ligament (PTFL) — the strongest lateral ligament. Rarely torn except in complete dislocation-level injuries.

When the ATFL and CFL heal in a lengthened, lax position, the mechanical restraint to ankle inversion is compromised. The ankle rolls more easily, and repeated sprains cause cumulative cartilage damage, synovitis, and progressive joint deterioration if instability goes uncorrected.

Who Gets Chronic Ankle Instability?

Risk factors for developing CAI after an initial sprain include:

• Inadequate rehabilitation of the initial sprain — returning to activity before ligament healing and proprioceptive recovery.
• High-demand athletic activity (soccer, basketball, volleyball, trail running) that challenges lateral ankle stability repeatedly.
• Cavovarus (high arch) foot type — places the foot in a position of supination that pre-loads the lateral ligaments.
• Underlying neuromuscular conditions affecting proprioception or peroneal muscle strength.
• Generalized ligamentous laxity — constitutional hypermobility that makes all ligament healing less tensile.

Symptoms of Chronic Ankle Instability

Patients with CAI typically report:

• Recurrent inversion sprains — occurring on flat ground, during routine activities, or with minimal provocation.
• Subjective “giving way” — the ankle feels like it might roll, even when it doesn’t actually sprain.
• Persistent lateral ankle tenderness — often along the ATFL and anterolateral joint line.
• Swelling and stiffness that never fully resolve between episodes.
• Avoidance behavior — limiting activities or terrains to avoid re-injury.
• Reduced confidence in ankle function during sport.

Diagnosis and Evaluation

Dr. Biernacki evaluates chronic ankle instability with a systematic assessment:

• Clinical examination — anterior drawer test (ATFL integrity) and talar tilt test (CFL integrity) with comparison to the contralateral ankle. Tenderness mapping, peroneal muscle strength testing, and proprioceptive assessment.
• Weight-bearing radiographs — baseline foot and ankle alignment, evidence of osteochondral lesions, coalition, or heel varus that may be contributing to instability.
• MRI — when the diagnosis is uncertain or to characterize associated pathology: cartilage lesions (OCD), peroneal tendon involvement, syndesmotic injury, or sinus tarsi syndrome coexisting with lateral instability.
• Stress radiographs — occasionally used to objectively quantify talar tilt under manual stress in ambiguous cases.

Non-Surgical Treatment: Functional Rehabilitation

A structured rehabilitation program addressing both mechanical laxity and neuromuscular deficits succeeds in a substantial proportion of patients with CAI. Dr. Biernacki prescribes a comprehensive program including:

• Peroneal strengthening — eccentric peroneal exercises rebuild the dynamic lateral stabilizers that compensate for ligamentous laxity.
• Balance and proprioceptive training — single-leg balance progression, wobble board and BOSU training, sport-specific movement patterns restore neuromuscular ankle protection.
• Ankle bracing — semi-rigid lace-up braces or articulated braces during sport provide external stability during the rehabilitation period.
• Custom orthotics — in patients with cavovarus foot type, laterally wedged orthotics reduce the propensity for ankle inversion during gait.

Functional rehabilitation with dedicated physical therapy for 8–12 weeks is the standard first-line treatment. Patients who complete a structured program have significantly better outcomes than those who simply rest and wait.

Surgical Treatment: The Broström-Gould Procedure

When adequate rehabilitation fails — typically defined as 3–6 months of structured therapy without achieving functional stability — anatomic ligament reconstruction (Broström-Gould procedure) is indicated. This procedure has become the gold standard for CAI treatment worldwide due to its excellent outcomes and preservation of ankle motion.

Procedure Description

Through a curvilinear incision along the anterolateral ankle, the attenuated ATFL is identified, shortened, and re-imbricated (tightened) back to its fibular origin with suture anchors. The inferior extensor retinaculum is advanced over the repair (the Gould modification) to provide additional capsular reinforcement and proprioceptive tissue coverage. The CFL is assessed and addressed if lax. The procedure restores anatomic ligament tension without constraining normal ankle motion.

Arthroscopic-Assisted Broström

When associated intra-articular pathology requires treatment — osteochondral lesions, anterior impingement spurs, loose bodies, or synovitis — Dr. Biernacki performs ankle arthroscopy through two anterior portals before proceeding with the open Broström. This “one-stop” approach addresses all pathology in a single operative session.

Recovery After Broström Reconstruction

Post-operative rehabilitation after Broström-Gould follows a staged protocol:

• Weeks 1–2: Splint or cast, non-weightbearing or protected weightbearing. Elevation.
• Weeks 2–4: Boot walker, progressive weightbearing. Range of motion begins.
• Weeks 4–8: Transition to brace, walking without boot. Peroneal strengthening and proprioception training begin.
• Weeks 8–12: Sport-specific training, jogging, cutting and lateral movements.
• Month 3–4: Return to sport with functional brace. Full unrestricted return at 4–6 months for most athletes.

Outcomes and Long-Term Results

The Broström-Gould procedure demonstrates 85–95% excellent/good results in published series with long-term follow-up exceeding 10 years. Re-injury rates are substantially lower than with non-anatomic reconstructions. Return to competitive sport rates are high, and the procedure is considered among the most reliable surgical interventions in foot and ankle surgery.

Serving Michigan Athletes with Ankle Instability

Dr. Biernacki evaluates chronic ankle instability in athletes of all levels from across Michigan — high school and collegiate athletes, adult recreational players, trail runners, and older patients whose daily activity is limited by unreliable ankle function. If your ankle continues to give way despite rehabilitation, a surgical consultation will clarify whether reconstruction is the right next step.

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.
