Unicompartmental knee replacement in the elderly may be associated with a better outcome than total knee replacement. The purpose of this review was to assess the clinical outcome in patients over the age of 70. A computerised search was performed using Pubmed and Embase. Quality assessment was performed using the Newcastle-Ottawa Scale. Eligible studies were identified according to defined criteria and reviewed in terms of peri-operative events, functional outcome and long-term results. 20 studies, representing a minimum of 2956 knees were included. There was a significant increase in the knee society score in the majority of studies to 89.5 (objective) and 80 (function) and the median range of motion (ROM) achieved was 115 degrees. There was no peri-operative mortality and the 10 year prosthesis survival rate was 87.5-98% Revision for periprosthetic infection was low at 0.13-0.30%.
对于老年人而言，单髁膝关节置换术的效果可能优于全膝关节置换术。本综述的目的是评估70岁以上患者的临床结局。使用PubMed和Embase进行了计算机检索。采用纽卡斯尔-渥太华量表进行质量评估。根据既定标准确定符合条件的研究，并从围手术期事件、功能结局和长期结果方面进行综述。纳入了20项研究，最少涉及2956个膝关节。大多数研究中，膝关节协会评分显著提高至89.5（客观评分）和80（功能评分），实现的中位活动范围（ROM）为115度。围手术期无死亡病例，10年假体生存率为87.5%-98%。假体周围感染的翻修率较低，为0.13%-0.30%。
