A multi-centre clinical trial of ICLH (Freeman-Swanson) arthroplasty has been in progress since 1971. In this paper the results up to two years after operation are reported in seventy-one knees displaying at least 30 degrees of fixed flexion, 25 degrees of valgus or 20 degrees of varus, before operation. It has been found that knees displaying 70 degrees of fixed flexion, 70 degrees of valgus, 30 degrees of varus or 50 degrees of valgus/varus instability can be satisfactorily aligned and stabilised with acceptable function. Three knees required revision. The other complications are listed and were unremarkable in nature. These results depend upon the prosthesis and upon the operative technique. The latter avoids damage to healthy bone but does involve the replacement of the tissues in the midline of the knee.
自1971年以来，一项关于ICLH（弗里曼 - 斯旺森）人工关节置换术的多中心临床试验一直在进行。本文报告了71例术前至少有30度固定屈曲、25度外翻或20度内翻的膝关节术后两年的结果。已发现，有70度固定屈曲、70度外翻、30度内翻或50度外翻/内翻不稳定的膝关节能够通过可接受的功能得到满意的对线和稳定。有3例膝关节需要翻修。其他并发症也被列出，其性质并不显著。这些结果取决于假体和手术技术。后者避免了对健康骨骼的损伤，但确实涉及到膝关节中线组织的置换。
