Chronic ankle instability：an analysis based on anatomical structure and biomechanical characteristics of the ankle joint / 中国组织工程研究

ABSTRACT

BACKGROUND:Chronic ankle instability can cause traumatic joint disease and secondary adhesive capsulitis, and even result in permanent dysfunction. OBJECTIVE: To explicit the forming reason of chronic ankle instability and to investigate the diagnosis and treatment methods of chronic ankle instability based on the biomechanical analysis of the ankle joint. METHODS: PubMed and Wanfang databases were retrieved for review and basic research papers about the anatomy, biomechanics, diagnosis and treatment of chronic ankle instability published from January 1990 to December 2014. The keywords were “chronic ankle instability, anatomy of ankle joint, biomechanics, therapy, research” in English and Chinese, respectively. After screening, 40 papers were included to summarize the anatomical structure of the ankle joint, mechanism and classification, diagnostic methods, and treatment methods of chronic lateral ankle instability. RESULTS AND CONCLUSION:Diagnostic methods of chronic ankle instability include ankle varus stress test, ankle anterior drawer test, ultrasonic test, modern imaging detection; and therapeutic methods for chronic ankle instability can be divided into conservative treatment and surgical treatment, and the surgical treatment can be subdivided into non-anatomic reconstruction and anatomical repair of the damaged ligament. Early diagnosis and effective treatment are recommended for patients with chronic ankle instability, and the treatment programs should be determined based on comprehensive analysis of ankle anatomical structure, biomechanical characteristics, pathogenesis, and diagnostic results.
