title: Lateral ankle instability: MR imaging of associated injuries and surgical treatment procedures.
abstract: Chronic ankle instability has been defined as the development of recurrent ankle sprains and persistent symptoms after initial lateral ankle sprain. The diagnosis of ankle instability is usually established on the patient's history, physical examination, and radiographic assessment. Patients have signs of both functional and mechanical instability, and the repetitive, chronic nature of the injury may lead to intra-articular and periarticular pathologies. This article discusses the incidence, etiology, and magnetic resonance (MR) imaging of these pathologies, reviews the surgical treatment procedures for lateral ankle instability, and presents the postoperative MR imaging findings.
