The most frequent technical difficulty encountered at unicompartmental knee arthroplasty (UKA) revision to total knee arthroplasty (TKA) is filling in all bone defects. These bone defects can render difficult components positioning, mechanical axis restitution, and ligament balance assessment, which are the three most important parameters for successful TKA. We describe a computer-assisted technique which makes it possible to control these three parameters before removal of the implants that have caused the bone defects. Our study is based on a series of 20 cases, with a minimum follow-up of 2 years. The anatomical and clinical results were very satisfying and comparable to results of primary TKA. We recommend this computer-navigated technique, which is as simple as a primary TKA procedure.
在单髁膝关节置换术(UKA)翻修为全膝关节置换术(TKA)时,最常见的技术难题是填补所有的骨缺损。这些骨缺损会导致难以进行组件定位、机械轴恢复和韧带平衡评估,而这些是 TKA 成功的三个最重要参数。我们描述了一种计算机辅助技术,该技术可在移除导致骨缺损的植入物之前控制这三个参数。我们的研究基于一系列 20 例病例,随访时间至少为 2 年。解剖学和临床结果非常满意,与初次 TKA 的结果相当。我们推荐这种计算机导航技术,它与初次 TKA 一样简单。
