A review of 11.5 year (average interval) follow-up examination of 409 low friction arthroplasties performed included only 3 late failures. The excellent results of the successes have been fully maintained for as long as 14 years. This was true with regard to pain, function of walking and mobility. Resorption of the calcar femorale was rare and no correlation was found with the wear of the socket. The average wear of 1.5 mm was less than predicted by Professor Sir John Charnley. Although 10 patients (7.8%) had excessive wear no patient is at present near the stage of requiring replacement of the socket for this reason. No adverse reaction was found to the implant or the cement.
对409例低摩擦人工关节置换术进行的11.5年（平均间隔时间）随访检查显示，仅有3例出现晚期失败。成功案例的优异结果在长达14年的时间里得到了充分维持。在疼痛、行走功能和活动能力方面均是如此。股骨矩吸收很少见，且与髋臼磨损无相关性。平均磨损1.5毫米，低于约翰·查恩利爵士教授的预测。尽管有10例患者（7.8%）出现过度磨损，但目前尚无患者因该原因接近需要更换髋臼的阶段。未发现对植入物或骨水泥的不良反应。
