No Difference of Gait Parameters in Patients with Image-Free Robotic-Assisted Medial Unicompartmental Knee Arthroplasty Compared to a Conventional Technique: A Randomized Controlled Trial 

Description

The presentation, delivered by Cecile Batailler, focuses on a study comparing gait patterns between robotic and conventional unicompartmental knee arthroplasty. Funded by Smith and Nephew, the study aims to assess whether the robotic system can enhance implant positioning and alignment in knee surgeries without affecting clinical outcomes. The research involved a randomized clinical trial with two groups of 33 patients, examining preoperative and six-month postoperative gait patterns using a kinematic analysis system. Despite employing advanced robotic assistance, the results indicated no significant differences in gait patterns or clinical outcomes between the two surgical techniques. The presenter highlighted the study's limitations, including the challenges faced by patients during treadmill assessments and the need for longer follow-up periods to observe any potential differences in recovery speeds. Ultimately, the study concluded that both techniques yielded similar rehabilitative outcomes, consistent with previous literature on the efficacy of assistive technologies in knee surgeries.
