The ICLH (Imperial College-London Hospital) double cup hip replacement as it exists today consists of a metal femoral component which caps the femur and a polyethylene acetabular component which resurfaces the acetabulum. Both components are cemented in place. The first prosthesis was inserted in 1972 and during the following two years complications emerged which necessitated changes in the prosthesis and the operative technique. Since November 1974 there have been no changes in the prosthetic design or operative procedure and complications have been infrequent. An approach has been developed whereby trochanteric osteotomy is not necessary. Up to December 1977 159 hips were replaced in 154 patients. Clinically, the results of a successful double cup arthroplasty are similar to those obtained by conventional hip replacement. No deterioration in the quality of the results is suggested when early results are compared with those of patients who are now two years and longer since surgery. Technical errors to be avoided are varus placement of the femoral component and excessive vertical placement of the acetabular component. Conclusions drawn are tentative due to the fact that to date the follow-up period is inadequate.
如今的帝国理工学院-伦敦医院（ICLH）双杯髋关节置换术由一个覆盖股骨的金属股骨部件和一个使髋臼重新表面化的聚乙烯髋臼部件组成。两个部件都用骨水泥固定到位。首例假体于1972年植入，在随后的两年中出现了并发症，这就需要对假体和手术技术进行改进。自1974年11月以来，假体设计或手术程序没有变化，并发症也很少见。已经开发出一种方法，不需要进行转子截骨术。截至1977年12月，154例患者的159个髋关节进行了置换。临床上，成功的双杯关节成形术的结果与传统髋关节置换术的结果相似。将早期结果与术后两年及更长时间的患者结果进行比较时，未发现结果质量有恶化情况。需要避免的技术错误是股骨部件的内翻放置和髋臼部件的过度垂直放置。由于迄今为止随访期不足，得出的结论是初步的。
