Fifty-two consecutive cemented total knee arthroplasties were performed using the Press-Fit Condylar (DePuy, Warsaw, Ind) knee system on patients aged 55 years or younger at Mayo Clinic Rochester from 1988 to 1994. Patients were followed for a minimum of 10 years, with an average follow-up of 12 years (range, 10-15 years). There were 8 total revisions (15%), including 2 revisions before 10 years, one for sepsis at 1 year, and one for instability at 8 years. Six revisions occurred between 10 and 15 years, all associated with polyethylene wear and osteolysis. Implant survival rate was estimated to be 96% at 10 years and 85% at 15 years of follow-up.
1988年至1994年期间，在梅奥诊所罗切斯特分院，对55岁及以下的患者使用压配髁型（迪普伊公司，印第安纳州华沙）膝关节系统连续进行了52例骨水泥型全膝关节置换术。对患者进行了至少10年的随访，平均随访时间为12年（范围为10 - 15年）。共有8例翻修手术（15%），其中2例在10年之前翻修，1例在1年时因感染性休克翻修，1例在8年时因不稳定翻修。6例翻修发生在10至15年之间，均与聚乙烯磨损和骨溶解有关。随访10年时植入物生存率估计为96%，15年时为85%。
