The most important clinical decision with Chronic Lateral Ankle Instability Reconstruction Michigan Podiatrist isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
Understanding Chronic Lateral Ankle Instability
Chronic lateral ankle instability (CLAI) affects an estimated 20–40% of patients who sustain acute lateral ankle sprains. After the initial injury, inadequate healing of the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) leaves the lateral ankle structurally deficient. Patients report repeated giving-way episodes with minimal provocation — stepping on uneven surfaces, descending stairs, or turning during sports — accompanied by pain, swelling, and progressive loss of confidence in the ankle. Over time, recurrent instability can cause osteochondral lesions of the talus, peroneal tendon injury, and accelerated ankle arthritis if left untreated.
Diagnosis of Chronic Ankle Instability
Dr. Biernacki performs a thorough clinical evaluation including the anterior drawer test (ATFL integrity) and talar tilt test (CFL integrity), comparing laxity between the symptomatic and contralateral ankles. Stress X-rays quantify ligamentous laxity. MRI evaluates the ligament morphology, identifies osteochondral lesions, and assesses peroneal tendon integrity — all relevant to surgical planning. Differential diagnoses including peroneal tendon tears, sinus tarsi syndrome, and osteochondral lesions may coexist and must be identified for complete treatment.
Conservative Treatment
For patients with mild-to-moderate instability, comprehensive conservative care is the appropriate first approach. Functional rehabilitation with proprioceptive and neuromuscular training addresses the balance deficits and muscle weakness that contribute to recurrent sprains. Peroneal muscle strengthening — the primary dynamic stabilizers of the lateral ankle — is a cornerstone of physical therapy. Ankle bracing provides mechanical support during high-risk activities. Activity modification and appropriate footwear selection further reduce reinjury risk. Patients with significant improvement after 3–6 months of dedicated rehabilitation may not require surgery.
Surgical Reconstruction: The Brostrom-Gould Procedure
Patients who fail conservative care, athletes requiring high-level ankle stability, and those with objective instability on stress imaging are candidates for surgical reconstruction. The modified Brostrom-Gould procedure — the gold standard for CLAI — directly repairs and tightens the native ATFL and CFL, reinforced with the inferior extensor retinaculum for additional stability. The procedure preserves the native ligament tissue, has excellent long-term outcomes (greater than 85% patient satisfaction at 10+ years), and allows return to sport in 4–6 months. Arthroscopic evaluation at the time of surgery allows identification and treatment of concomitant osteochondral lesions or sinus tarsi pathology. For revision cases or patients with ligament tissue insufficient for primary repair, allograft or autograft reconstruction may be performed.

Dr. Tom Biernacki’s Recommendation
Chronic ankle instability is one of those conditions that patients often blame themselves for — ‘I just have weak ankles.’ But the reality is that after a significant ligament injury, the ankle’s structural restraints may never heal adequately on their own, and proprioception training can only compensate so much. If you’re tired of your ankle giving out, come see us — there’s a very effective surgical solution with an excellent track record.

Frequently Asked Questions
How many ankle sprains make it ‘chronic’ instability?
There’s no magic number, but recurrent giving-way episodes — whether after 2 sprains or 20 — combined with objective laxity on examination suggest functional and mechanical instability that warrants evaluation. The pattern matters more than the count.
Is the Brostrom procedure outpatient?
Yes — the modified Brostrom-Gould procedure is typically performed as an outpatient surgery under regional or general anesthesia. Patients go home the same day with a splint, and begin gentle range-of-motion exercises within 1–2 weeks.
Will I be able to return to sports after ankle ligament surgery?
The vast majority of active patients return to their sport after Brostrom reconstruction. Return to full cutting and pivoting sport is typically expected at 4–6 months post-operatively. Proper rehabilitation is essential to achieving the best outcome.
Can ankle instability cause arthritis?
Yes — recurrent giving-way episodes cause repeated micro-trauma to the ankle joint cartilage. Over years to decades, chronic instability is a significant risk factor for developing ankle osteoarthritis. Early stabilization reduces this long-term risk.
