One hundred Charnley low-friction arthroplasties have been reviewed at 15 to 17 years. Thirty-five of the patients have died. A revision rate of 16 per cent has been recorded. Only two cases demonstrated cavitation and cortical destruction of the femur, and these cases were revised successfully. One of the major causes for revision was fracture of the femoral component. With modern alloys, this should not be a long-term problem. Our data would suggest that the cemented arthroplasty can be used with confidence in patients 65 and older. It is our hope that modern cement technology and component design will increase the longevity of the cemented arthroplasty.
对100例接受Charnley低摩擦关节成形术的患者进行了15至17年的随访。其中35例患者已死亡。记录的翻修率为16%。仅2例出现股骨空洞和皮质破坏，这2例均成功进行了翻修。翻修的主要原因之一是股骨部件骨折。采用现代合金，这不应成为一个长期问题。我们的数据表明，骨水泥型关节成形术可放心用于65岁及以上的患者。我们希望现代骨水泥技术和部件设计能提高骨水泥型关节成形术的使用寿命。
