Abstract
Ankle osteoarthritis (OA) is less common than knee and hip OA, and 75% to 80% of all presentations are posttraumatic in nature, resulting from either ligamentous or bony injury to the ankle. While the ankle joint cartilage demonstrates capacity for self-restoration, the ankle joint is sensitive to aberrancies in biomechanics and the inflammatory milieu after an injury is thought to contribute to the onset of posttraumatic ankle OA. Conservative care for ankle OA is currently centered on pain reduction, and derivatives that may delay the progression of ankle OA are the subject of ongoing investigation. Surgical management for end-stage ankle OA currently focuses on ankle arthrodesis and total ankle arthroplasty. Specific indication for one procedure over the other is the topic of much debate. While total ankle arthroplasty has become more frequently used with the advent of newer generation systems, ankle arthrodesis may still be favored in younger patients with high-demand occupations.
踝关节骨关节炎（OA）比膝关节和髋关节 OA 更不常见，75% 到 80% 的病例都是创伤后性质的，由踝关节韧带或骨骼损伤引起。虽然踝关节软骨具有自我修复能力，但踝关节对生物力学的失常非常敏感，受伤后的炎症环境被认为是创伤后踝关节 OA 的发病原因。目前，踝关节 OA 的保守治疗主要以减轻疼痛为中心，而可延缓踝关节 OA 病程进展的衍生物则是正在研究的课题。踝关节 OA 终末期的手术治疗目前主要集中在踝关节固定术和全踝关节置换术上。两种手术的具体适应症存在很大争议。虽然随着新一代系统的出现，全踝关节置换术的应用越来越广泛，但对于从事高要求职业的年轻患者来说，踝关节置换术可能仍然更受青睐。
期刊介绍：
The Journal of the American Academy of Orthopaedic Surgeons was established in the fall of 1993 by the Academy in response to its membership’s demand for a clinical review journal. Two issues were published the first year, followed by six issues yearly from 1994 through 2004. In September 2005, JAAOS began publishing monthly issues.
Each issue includes richly illustrated peer-reviewed articles focused on clinical diagnosis and management. Special features in each issue provide commentary on developments in pharmacotherapeutics, materials and techniques, and computer applications.
