The case of an atraumatic dislocation of a fixed bearing in a medial unicompartmental arthroplasty with an oxinium femoral component is presented. A review of the literature pertaining to knee arthroplasty locking mechanisms is discussed. Potential modes of locking mechanisms failure are reviewed including the recognition of such failures in the clinical setting. This is the first report of a dislocated fixed-bearing medial oxinium unicompartmental arthroplasty and consequent metal arthrogram.
本文介绍了一例采用氧化锆股骨部件的内侧单髁置换术中固定平台发生非创伤性脱位的病例。文中讨论了与膝关节置换锁定机制相关的文献综述。回顾了锁定机制失败的潜在模式,包括在临床环境中对此类失败的识别。这是首例关于固定平台内侧氧化锆单髁置换术脱位及由此导致的金属关节造影的报告。
