The purpose of our study was to investigate the mid-term clinical and functional outcomes of robotic-arm assisted Bicompartmental knee arthroplasty (BiKA).
This study reviewed a single-centre prospectively maintained cohort of 50 patients (53 knees) who underwent BiKA (patellofemoral and medial compartment) at 5- and 7-year postoperative follow-up.
Mean follow-up was 7.1 ± 0.1 years (range, 7.0-7.3). Kaplan-Meier survivorship rates at 5 and 7 years were 96% and 93%, respectively. At 7-year follow-up, patient satisfaction was 76% satisfied, 13% neutral, and 11% not satisfied. Mean KSS-FS was 80.5 ± 15.8 (range, 30-100) with 82% of patients reporting walking more than 10 blocks, 89% reporting walking without support, and 100% able to go up and down stairs with 61% requiring use of a rail. Three patients (four knees) underwent revision surgery.
Our study reported excellent survivorship and functional outcomes, and good-excellent satisfaction at mid-term follow-up for robotic-arm assisted BiKA.
本研究旨在探讨机器人辅助双间室膝关节置换术（BiKA）的中期临床和功能结果。
本研究回顾了单中心前瞻性维护队列的 50 例患者（53 膝），这些患者在术后 5 年和 7 年进行了 BiKA（髌股和内侧间室）。
平均随访时间为 7.1±0.1 年（范围为 7.0-7.3）。Kaplan-Meier 生存率在 5 年和 7 年分别为 96%和 93%。在 7 年的随访中，患者满意度为 76%满意，13%中立，11%不满意。平均 KSS-FS 为 80.5±15.8（范围为 30-100），82%的患者报告行走超过 10 个街区，89%的患者报告无需支撑行走，100%的患者能够上下楼梯，其中 61%的患者需要使用扶手。3 名患者（4 膝）接受了翻修手术。
我们的研究报告了机器人辅助 BiKA 的优异生存率和功能结果，以及中期随访时良好到优秀的满意度。
