本文报告88例(94膝)双股骨型人工膝关节置换术。随访时间2~4年，平均3年。类风湿性关节炎与骨关节炎患者的比例为3：1。总体结果为优37.5%，良37.5%，可16%，差9%。失败和效果差的主要原因是：(1)畸形矫正不足或过度，导致膝关节半脱位和/或不稳定；(2)胫骨假体松动；(3)髌股关节出现症状。修正率为5.5%。骨水泥粘结处的渐进性透射率为26%，其中16%的骨水泥粘接处的透过率为1 mm，10%的骨水泥粘接处的透射率在1.5-3 mm之间。为了进一步提高关节置换的效果，应考虑(1)置换髌股关节，(2)在适当的器械的帮助下，在适当的韧带和关节囊的正确张力下，将假体插入适当的解剖位置，(3)改进胫骨假体的固定。
This is a report of 94 knees in 88 patients with the duo-condylar type of knee arthroplasty. The follow-up period of time was between 2 to 4 years with an average of 3 years. The rheumatoid to osteoarthritic patient ratio was 3 to 1. The overall results were excellent in 37.5 per cent, good in 37.5 per cent, fair in 16 per cent, and poor in 9 per cent. The main causes of failure and poor results were: (1) under or over correction of deformity leading to subluxation and/or instability of the knee; (2) loosening of the tibial component, and (3) symptoms arising from the patellofemoral joint. The revision rate is 5.5 per cent. The progressive radiolucency at the cement bone bond is 26 per cent of which 16 per cent is up to 1 mm and 10 per cent is between 1.5 to 3 mm. To further improve the results of arthroplasty, one should take into consideration (1) replacement of the patellofemoral joint, (2) insertion of the prosthesis in the proper anatomical location under correct tension of the ligaments and capsule with the help of proper instrumentation and (3) improvement in fixation of the tibial component.
