Ankle instability is one of the most common chronic musculoskeletal complaints in the active population, yet it remains significantly undertreated — largely because many patients and providers accept ankle “giving way” as an inevitable consequence of prior sprains. Chronic ankle instability is not an inevitable outcome of ankle sprains. It is a specific pathological condition with identifiable anatomic causes and effective treatments that, when appropriately matched to the underlying pathology, produce lasting resolution.

Functional vs. Mechanical Instability

The distinction between functional and mechanical instability is essential for guiding treatment:

• Functional instability: Subjective sense of instability and giving way without objective ligament laxity on stress testing. Caused by proprioceptive deficits, peroneal muscle weakness, and neuromuscular dyscoordination from the original sprain injury. Responds well to targeted rehabilitation, proprioceptive training, and bracing.
• Mechanical instability: Objective ligamentous laxity on stress examination (positive anterior drawer, talar tilt) and/or stress radiographs showing abnormal talar tilt. Caused by structural incompetence of the lateral ankle ligaments (ATFL ± CFL). Often requires surgical reconstruction for lasting correction in active individuals.

Most patients have a combination of both components. Thorough clinical evaluation determines the relative contribution of each.

Conservative Treatment: The Essential Foundation

Before considering surgery, a minimum 3–6 months of structured conservative management is standard:

• Peroneal strengthening: The peroneus longus and brevis are the primary dynamic stabilizers of the lateral ankle. A progressive resistance program targeting eversion strength and eccentric control is the cornerstone of rehabilitation.
• Proprioceptive training: Balance board, BOSU ball, and single-leg stance progressions retrain the neuromuscular response that prevents the ankle from rolling. Research demonstrates that proper proprioceptive rehabilitation reduces functional instability as effectively as surgery in many patients.
• Ankle bracing: Functional lace-up braces (not rigid stirrup braces) provide lateral ankle support while allowing normal dorsiflexion and plantarflexion — appropriate for sport and high-risk activities. Bracing does not restore ligament integrity but significantly reduces re-sprain incidence.
• Taping: Closed-basketweave athletic taping and kinesiotaping techniques provide proprioceptive feedback and some mechanical restriction during sport. Taping is best used as a temporary adjunct during return-to-sport rather than a primary long-term solution.

When Conservative Management Fails

Surgical consultation is appropriate when:

• Ankle giving way continues despite 3–6 months of dedicated rehabilitation
• Mechanical ligament laxity is confirmed on examination or stress radiographs
• The patient is unable to participate in desired sport or activity without functional limitation
• Associated pathology (osteochondral lesion, peroneal tendon tear) requires surgical treatment

Surgical Options for Chronic Ankle Instability

The Broström-Gould procedure is the gold-standard anatomic reconstruction for chronic lateral ankle instability — repairing and reinforcing the ATFL and CFL at their native attachment sites. Success rates exceed 90% at long-term follow-up. InternalBrace augmentation is an option for patients requiring faster rehabilitation return.

Non-anatomic tenodesis procedures (Watson-Jones, Evans) sacrifice peroneal tendon tissue to create a non-native lateral restraint — associated with higher rates of subtalar stiffness and adjacent joint arthritis over time. These have largely been supplanted by anatomic Broström techniques.
