The authors have analyzed the results obtained with 63 "Geometric" total knee arthroplasties with a follow-up of more than five years. Four septic complications and nine loosenings were observed. Three main causes that have been noted were 1) unsatisfactory operative indications, 2) poor positioning of the prosthesis, 3) poor design of the prosthesis. The last point has led to a new design of prosthesis called "anametric" because its design is closer to that of normal anatomy. The "geometric" model should be considered as a first generation of prosthesis.
作者分析了63例“几何型”全膝关节置换术超过五年的随访结果。观察到4例感染并发症和9例松动。已注意到的三个主要原因是：1）手术适应症不理想；2）假体定位不佳；3）假体设计不佳。最后一点促使了一种名为“非等距型”的新假体设计的出现，因为其设计更接近正常解剖结构。“几何型”假体模型应被视为第一代假体。
