Twenty-one cases of the Charnley low-friction arthroplasty were revised because of recurrent or irreducible dislocation. Three main reasons for this revision, usually in combination, were identified: loss of the abductor mechanism due to trochanteric detachment; shortening of the limb due to high placement of the socket or low section of the femoral neck; and malorientation of the components. Sixteen patients had no further problems after revision. One patient had a single dislocation, four had more than one dislocation although they managed to cope with them and did not require a further revision.
21例Charnley低摩擦关节成形术因复发性脱位或不可复位性脱位而进行翻修。确定了这种翻修的三个主要原因，通常是综合出现：由于大转子分离导致外展肌机制丧失；由于髋臼位置过高或股骨颈截骨过低导致肢体缩短；以及假体组件方向不良。16例患者翻修后未再出现问题。1例患者发生单次脱位，4例患者发生多次脱位，尽管他们能够应对这些脱位且无需进一步翻修。
