Chronic Lateral Ankle Instability — Recurrent Sprains Michigan Podiatrist

Medically reviewed by Dr. Tom Biernacki, DPM — Board-Certified Podiatric Surgeon — Balance Foot & Ankle, Howell & Bloomfield Hills, MI. Last updated April 2026.

What Is Chronic Lateral Ankle Instability?

Chronic lateral ankle instability (CLAI) is a condition where an ankle that has sustained one or more lateral sprains continues to give way, feels unstable during activity, and experiences recurrent sprains — despite apparently completing initial rehabilitation. It affects approximately 20–40% of patients following acute ankle sprains and results from both mechanical instability (damaged, elongated lateral ankle ligaments) and functional instability (proprioceptive deficits, peroneal muscle weakness). At Balance Foot & Ankle in Howell and Bloomfield Hills, Michigan, Dr. Tom Biernacki, DPM provides comprehensive CLAI evaluation and management. Call (810) 206-1402.

Why Some Ankles Never Fully Recover from Sprains

The ATFL and CFL ligaments — the primary lateral ankle restraints — heal with elongation rather than at their original length when rehabilitation is inadequate. Simultaneously, the ankle’s proprioceptive nerve endings are damaged, leading to delayed peroneal muscle response during sudden foot inversion. The result: a mechanically lax ankle with impaired neuromuscular protection. In our clinic, most CLAI patients completed Phase 1 rehabilitation (pain gone, walking normally) but skipped the critical Phase 2–3 peroneal strengthening and proprioception training that actually restores mechanical and functional stability.

Conservative Rehabilitation Protocol

Comprehensive Phase 2–3 rehabilitation resolves functional instability in 60–70% of CLAI patients without surgery. Phase 2 (weeks 3–8): peroneal eversion strengthening with resistance band; proprioception training on a wobble board starting with two-leg, progressing to single-leg; joint position sense exercises; gradual return to straight-line running. Phase 3 (weeks 8–12+): sport-specific agility drills; single-leg functional testing (single-leg squat, single-leg hop, Y-balance test) before clearance for return to sport. Patients who pass all Phase 3 criteria have re-sprain rates comparable to patients who never had instability.

Bracing and Orthotics for Chronic Ankle Instability

Lace-up ankle braces (such as the ASO ankle brace) reduce re-sprain rates by 30–50% during sport participation — appropriate during rehabilitation but not as a long-term substitute for rehabilitation. Custom orthotics with a lateral flare can reduce the foot’s tendency to roll outward in patients with high arches (cavus foot), a significant CLAI risk factor. We evaluate each patient’s biomechanics to determine whether orthotic modification is indicated alongside rehabilitation.

Surgical Reconstruction — Brostrom-Gould Procedure

Surgical ankle ligament reconstruction is indicated after comprehensive 4–6 month rehabilitation failure, recurrent sprains despite bracing, or associated OCD requiring arthroscopic treatment. The Brostrom-Gould procedure — direct repair and imbrication of the ATFL and CFL, augmented with the extensor retinaculum — achieves 85–95% success rates. Recovery: 4–6 weeks non-weight-bearing, 3–4 months to full activity, 6 months to competitive sport. Associated pathology (OCD, peroneal tears, sinus tarsi syndrome) must be identified on MRI and addressed simultaneously for optimal outcomes.

Red Flags

Seek urgent evaluation for: an ankle that locks or catches during movement (loose body — osteochondral fragment); progressive worsening despite bracing and rehabilitation; single-leg balance impossible even on a solid surface; or deep ankle pain with activity suggesting an OCD lesion that needs treatment before the cartilage deteriorates further.
