文献中很少有关于年轻患者全膝关节置换术结果的报道。本研究旨在评价55岁以下患者行全膝关节置换术的结果。在1974年至1982年期间，对62例患者进行了93例膝关节置换术。术前诊断为类风湿性关节炎76膝，骨关节炎17膝。所有膝关节均采用全髁膝关节假体。在13个膝关节中观察到胫骨平台缺陷，需要补充支撑。90例膝关节（17例骨关节炎和73例类风湿性关节炎）可用于平均6.1年的随访研究。整个组的膝关节评分为87.1。骨关节炎和类风湿性关节炎组的亚组评分也为87.1。X线评价显示透亮率为30%。发现两个植入物具有整体射线可透性，并认为其松动。生存率分析显示，整个组10年的累积生存率为96%。这些结果与老年患者全膝关节置换术的长期结果相当，优于年轻患者全髋关节置换术的结果。全膝关节置换术在年轻患者中是一种可靠和持久的手术，但应谨慎使用，尽管这里报道的结果很好。
There are few reports in the literature that deal with the results of total knee arthroplasty in the younger patient. The present study was undertaken to evaluate the results of total knee arthroplasty in patients under the age of 55 years. Ninety-three knee arthroplasties in 62 patients were performed between 1974 and 1982. The preoperative diagnosis was rheumatoid arthritis in 76 knees and osteoarthritis in 17 knees. The total condylar knee prosthesis was used in all knees. Defects in the tibial plateau were noted in 13 knees, and supplemental support was required. Ninety knees (17 with osteoarthritis and 73 with rheumatoid arthritis) were available for follow-up study at a mean of 6.1 years. The knee rating for the entire group was 87.1. The subgroup scores for the osteoarthritis and rheumatoid arthritis groups were also 87.1. Roentgenographic evaluation revealed a lucency rate of 30%. Two implants were found to have global radiolucencies and were considered loose. Survivorship analysis resulted in a cumulative survivorship rate of 96% at ten years for the entire group. These results are comparable to the long-term results of total knee arthroplasty in the older patient and better than the results of total hip arthroplasty in the younger patient. Total knee arthroplasty in the younger patient is a reliable and durable procedure but should be used with caution despite the excellent results reported here.
