The current study was designed to determine (1) 10-year implant survival and (2) patient's self-reported functional outcome in a single surgeon's consecutive cohort of patients who had undergone minimally invasive unicondylar resurfacing with a modified cementation technique utilizing a cobalt-chromium femur/inlaid all-PE tibia, fixed-bearing unicompartmental prosthesis. We included 344 consecutive patients (361 knees) who had received the study device between January 2002 and December 2005 in this retrospective study. After 10 years, 78 patients (78 knees) had died, 59 (59 knees) were lost to follow-up and four (four knees) did not participate. Thirteen knees (11 patients) were revised after a mean of 5.8 ± 1.9 years. Hence, the study population at follow-up comprised 192 patients (207 knees). Ten-year implant survival was 94.6% (95% confidence interval, 90.9-96.8%). The Forgotten Joint Score and Oxford Knee Score were 68.9 ± 28.9 and 39 ± 9.1, respectively. Excellent survivorship and clinical outcomes were obtained with UKA with an inlaid all-PE tibia with a modified cementation technique.
（1）在一位外科医生连续收治的、采用改良骨水泥技术植入钴铬合金股骨/镶嵌式全聚乙烯胫骨固定平台单髁假体进行微创单髁表面置换的患者队列中，假体10年生存率；（2）患者自我报告的功能结局。在这项回顾性研究中，我们纳入了2002年1月至2005年12月期间接受该研究装置的344例连续患者（361个膝关节）。10年后，78例患者（78个膝关节）死亡，59例（59个膝关节）失访，4例（4个膝关节）未参与。13个膝关节（11例患者）在平均5.8±1.9年后进行了翻修。因此，随访时的研究人群包括192例患者（207个膝关节）。假体10年生存率为94.6%（95%置信区间，90.9 - 96.8%）。遗忘关节评分和牛津膝关节评分分别为68.9±28.9和39±9.1。采用改良骨水泥技术的镶嵌式全聚乙烯胫骨单髁置换术获得了优异的生存率和临床结局。
