A novel active robotic system for total knee arthroplasty (TKA) performs automated milling of bone surfaces. Study objectives were to assess system safety and effectiveness in a US population.
A multicenter clinical trial was conducted, following 115 patients for at least 6-months. A pre-defined list of robot-related adverse events was used to evaluate safety. Efficacy was assessed radiographically comparing planned versus achieved coronal limb alignment.
No pre-defined adverse events occurred and postoperative limb alignment more than ±3° from plan occurred in 11.2 % of cases.
Active robotics for TKA is safe and effective as demonstrated in this trial.
一种用于全膝关节置换术(TKA)的新型主动机器人系统可对骨表面进行自动铣削。研究目的是评估该系统在美国人群中的安全性和有效性。
进行了一项多中心临床试验,对115名患者进行了至少6个月的随访。使用预先定义的与机器人相关的不良事件列表来评估安全性。通过影像学比较计划的与实际实现的冠状位肢体对线来评估疗效。
未发生预先定义的不良事件,11.2%的病例术后肢体对线与计划相差超过±3°。
本试验表明,用于TKA的主动机器人技术是安全有效的。
