Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older who are eligible for total knee replacement.

Probably not a fit

Patients with extreme malalignment requiring special implants or those unfit for surgery due to other medical conditions may not benefit from this study.

What this trial studies

This study evaluates the clinical and economic impacts of Robotic-Assisted Total Knee Replacement (RTKR) versus conventional Total Knee Replacement (TKR). It aims to determine if RTKR offers improved precision and better patient outcomes, as measured by the Forgotten Joint Score and other patient-reported outcome measures. The study is designed as a multicenter, randomized, controlled trial with two treatment arms, focusing on adult patients eligible for knee replacement surgery. Secondary endpoints include activity levels, implant positioning accuracy, and adverse event rates.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced healthcare costs for patients undergoing knee replacement.

How similar studies have gone: Other studies have shown promising results with robotic-assisted surgical techniques, suggesting potential benefits in precision and outcomes.
