A prospective follow-up using a standardized data recording form was carried out by independent, experienced orthopedic surgeons on a small number (116) of knees operated upon at The London Hospital in the period January 1, 1971 to October 31, 1973. An additional 93 knees have been operated upon at other hospitals and followed prospectively using the same data recording system. A total of 159 knees have been reviewed 2 to 4 years after operation. The complications specific to ICLH arthroplasty have been unremarkable and generally correctable. Two tibial components have sunk and have been revised at The London Hospital. The results show that ICLH arthroplasty has been used to correct satisfactorily flexion deformities up to 70 degrees, valgus deformities up to 45 degrees, and varus deformities up to 35 degrees. (Deformities of greater magnitude can be corrected but were not present among the knees in this study.) The operation may be said to be "worthwhile" with reference to pain in 94 per cent of the knees, with reference to the ability to walk in 80 per cent of the knees, and with reference to the range of movement in 71 per cent. Overall, 47 per cent of the knees had no complaint postoperatively, while a further 47 per cent were improved; thus for 94 per cent the procedure was "worthwhile."
1971年1月1日至1973年10月31日期间，由独立、经验丰富的骨科医生使用标准化数据记录表格对伦敦医院接受手术的少数（116例）膝关节进行了前瞻性随访。另外93例膝关节在其他医院接受了手术，并使用相同的数据记录系统进行前瞻性随访。共有159例膝关节在术后2至4年接受了复查。ICLH人工关节置换术特有的并发症并不显著，且一般可以纠正。伦敦医院有2个胫骨部件下沉并已进行翻修。结果表明，ICLH人工关节置换术已被用于令人满意地矫正高达70度的屈曲畸形、高达45度的外翻畸形和高达35度的内翻畸形。（更大程度的畸形可以矫正，但本研究中的膝关节中不存在此类畸形。）就94%的膝关节的疼痛而言、80%的膝关节的行走能力而言以及71%的膝关节的活动范围而言，该手术可以说是“值得的”。总体而言，47%的膝关节术后无不适，另有47%有所改善；因此，对于94%的患者来说，该手术是“值得的”。
