Unicompartmental knee arthroplasty (UKA) has a higher risk of revision than total knee arthroplasty (TKA), particularly for younger patients. The outcome of knee arthroplasty is typically defined as implant survival or revision incidence after a defined number of years. This can be difficult for patients to conceptualize. We aimed to calculate the 'lifetime risk' of revision for UKA as a more meaningful estimate of risk projection over a patient's remaining lifetime, and to compare this to TKA.

膝关节单髁置换术的终生翻修风险。

单髁膝关节置换术 (UKA) 比全膝关节置换术 (TKA) 具有更高的翻修风险，尤其是对于年轻患者。膝关节置换术的结果通常定义为固定年数后的植入物存活率或翻修率。这对于患者来说可能难以概念化。我们旨在计算 UKA 翻修的“终生风险”，作为对患者剩余寿命风险预测的更有意义的估计，并将其与 TKA 进行比较。
