The objective of this study was to compare the radiologic and clinical outcomes HURWA robotic-assisted total knee arthroplasty (TKA) those conventional TKA.A 150 patients were randomized into two groups - 73 77 underwent TKA TKA, respectively. Preoperative postoperative Western Ontario McMaster University Osteoarthritis Index (WOMAC) score, Hospital for Special Surgery (HSS) 36-item Short Form Health Survey (SF-36) Knee Society Score (KSS) range motion (ROM) obtained compared between these groups. preoperative hip-knee-ankle (HKA) angle rate HKA≤3° in also compared.The mean HKA 1.801° ​± ​1.608° varus group 3.017° ​2.735° group; values significantly different. alignment mechanical axis lower than 3° 81.2% 63.5%, Patients undergone or had similarly improved flexion functional recovery reflected by WOMAC HSS SF-36 score KSS.HURWA is a safe effective, resulting better TKA. improvement after similar However, longer follow-up needed determine whether will produce long-term outcomes.Recently, system has been introduced practice Several systems, including CASPAR, Tsolution, ROSA, ROBODOC Mako, have implemented application.However, application robotic systems limited due their technical complexity, insufficient versatility increased operative time. Until now, there are still no approved National Medical Products Administration China. Therefore, more need be designed improved, particularly Through our randomized, multicenter, single blind parallel controlled trial, we showed that robot-assisted effective which flexion.
