摘要

As science and technology continue to progress, the variety and number of robots used in assisted total knee arthroplasty (TKA) have steadily increased, allowing more surgeons and patients to benefit from enhanced medical precision and improved knee joint function, ultimately leading to a better quality of life. This retrospective study compared the outcomes of 164 patients undergoing total knee arthroplasty (TKA), either conventionally or assisted by one of three robotic systems (Brainlab, HURWA, or Stryker Cori), all within an Enhanced Recovery After Surgery (ERAS) protocol. Whilst robotic groups had longer incisions and the Brainlab system required more time, the domestic HURWA robot demonstrated superior performance in achieving optimal FFC and LFC angles. By postoperative day 3, the Brainlab group reported higher pain scores, but this difference resolved by 90 days. Crucially, there were no significant differences in final knee function (KSS, ROM), inflammatory markers, blood loss, complication rates, or patient satisfaction (all > 95%) between any groups. The findings indicate that despite early variations, all three robotic systems facilitate effective recovery and satisfactory clinical outcomes comparable to conventional TKA under ERAS, without increasing perioperative risks.
