We performed a survival analysis on 354 cemented primary press-fit condylar total knee arthroplasties in 277 patients with prospective follow-up (mean, 8.8 years; range, 0.3-16.9 years). The number of patients alive reaching 15 years at follow-up for survival analysis was 15. The cumulative survival rate at 15 years was 81.7% (95% confidence interval, 72.1%-88.5%), using revision for all causes as our end point. Indications for revision in our patient group were aseptic loosening 4.5%, infection 2.3%, and exchange of polyethylene insert 1.1%. Our results indicate that the cemented press-fit condylar total knee arthroplasty has a good long-term survival, at 15 years, based on revision as the end point.
我们对277例患者的354例骨水泥型初次压配髁型全膝关节置换术进行了生存分析，进行了前瞻性随访（平均8.8年；范围0.3 - 16.9年）。用于生存分析的随访中存活至15年的患者数量为15例。以所有原因翻修为终点，15年时的累积生存率为81.7%（95%置信区间，72.1% - 88.5%）。我们患者组的翻修指征为无菌性松动4.5%、感染2.3%以及聚乙烯内衬置换1.1%。我们的结果表明，以翻修为终点，骨水泥型压配髁型全膝关节置换术在15年时具有良好的长期生存率。
