What this trial studies

This clinical trial aims to evaluate the effectiveness of robotic arm-assisted surgery compared to traditional manual surgery in patients undergoing total knee replacement due to knee osteoarthritis. Participants will be randomly assigned to either the robotic-assisted group or the manual surgery group, with their joint awareness assessed using the Forgotten Joint Score over a follow-up period of 24 months. Secondary objectives include measuring pain levels, quality of life, knee function, and revision rates. The study will involve a total of 200 participants across multiple centers.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 who are listed for elective primary total knee replacement due to end-stage osteoarthritis.

Not a fit: Patients with significant knee deformities, those requiring patella resurfacing, or individuals unable to comply with study protocols may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved outcomes and enhanced joint awareness for patients undergoing knee replacement surgery.

How similar studies have performed: Other studies have shown promising results with robotic-assisted surgeries, indicating potential benefits over traditional methods.
