Abstract

We report a case of previously undescribed medial unicompartmental knee arthroplasty failure due to femoral component implant fracture. The patient experienced sudden pain and locking while ambulating 8 years postoperatively. Radiographs revealed catastrophic femoral component failure with a transverse break through the metal. The patient underwent revision to total knee arthroplasty. At 1-year follow-up, the patient had no pain and a range of motion of 130 degrees. Particular attention should be paid to obtaining adequate femoral component posterior flange fixation during unicompartmental knee arthroplasty. Patient education regarding maintaining a healthy weight is crucial to preventing this complication.

摘要

我们报告了一例因股骨组件植入物骨折导致先前未描述的内侧单髁膝关节置换失败的病例。患者术后8年行走时突然出现疼痛和卡顿。X线片显示股骨组件灾难性失败，金属出现横向断裂。患者接受了全膝关节置换翻修手术。在1年的随访中，患者无疼痛，活动范围为130度。在单髁膝关节置换术中，应特别注意获得足够的股骨组件后凸缘固定。对患者进行关于保持健康体重的教育对于预防这种并发症至关重要。
