The purpose of this paper is to systematically review the available literature to understand the effectiveness, the survivorship, the clinical outcomes and the complications of lateral UKA.
A review of the current literature available about lateral UKA was performed in March 2020, according to the PRISMA guidelines. Selection was based on the following inclusion criteria: (1) clinical reports of any level of evidence, (2) written in English language, (3) published from 1996 to 2020, (4) dealing with clinical data on lateral UKA. A total of 47 articles, published between 1996 and 2020, were included in the review. Quality of every article was assessed using the Modified Coleman Methodology Score.
A total of 47 studies were included. Mean mCMS was 45.27 (range 30-62). Mean age at surgery was 64.5 years (range 34.1-88.0 years). In 1741 patients (65.5%) a metal back implant was used and in 421 patients (15.8%) an all poly design was used. Several scores were used to evaluate clinical results (OKS, AKSS, IKS, KOOS, WOMAC, VAS). Range of motion improved with an overall mean value of 120.3° (range: 105.9°-143.3°). The mean follow-up was 60.7 months (range, 7-204 months), mean survivorship (absence of a revision) with a minimum 60 months of follow-up was 88.6% (range 74.5-100) and mean satisfaction of patients was 78.5% (range 41.0-97.9).
Lateral UKA seems to be an effective solution to manage lateral osteoarthritis (OA), based on preliminary results, with survivorship and satisfaction rate comparable to medial UKA and total knee arthroplasty (TKA). Nonetheless, this review highlights that the quality of studies available in current literature is low.
Systematic review of level IV studies.
本文旨在系统回顾现有文献，以了解外侧单髁置换术（UKA）的有效性、生存率、临床结果及并发症。
根据PRISMA指南，于2020年3月对有关外侧UKA的当前文献进行了综述。选择基于以下纳入标准：（1）任何证据水平的临床报告；（2）英文撰写；（3）1996年至2020年发表；（4）涉及外侧UKA的临床数据。共有47篇发表于1996年至2020年间的文章被纳入综述。使用改良科尔曼方法评分评估每篇文章的质量。
共纳入47项研究。平均改良科尔曼方法评分（mCMS）为45.27（范围30 - 62）。手术时的平均年龄为64.5岁（范围34.1 - 88.0岁）。1741例患者（65.5%）使用了金属背衬植入物，421例患者（15.8%）使用了全聚设计。采用了多种评分来评估临床结果（牛津膝关节评分（OKS）、美国膝关节协会评分（AKSS）、国际膝关节文献委员会评分（IKS）、膝关节损伤和骨关节炎疗效评分（KOOS）、西安大略和麦克马斯特大学骨关节炎指数（WOMAC）、视觉模拟评分（VAS））。活动范围有所改善，总体平均值为120.3°（范围：105.9° - 143.3°）。平均随访时间为60.7个月（范围，7 - 204个月），至少随访60个月的平均生存率（无翻修）为88.6%（范围74.5 - 100），患者的平均满意度为78.5%（范围41.0 - 97.9）。
基于初步结果，外侧UKA似乎是治疗外侧骨关节炎（OA）的有效解决方案，其生存率和满意度与内侧UKA及全膝关节置换术（TKA）相当。尽管如此，本综述强调当前文献中现有研究的质量较低。
IV级研究的系统综述。
