Study Summary

Twelve randomized controlled trials including 1538 patients with knee osteoarthritis (KOA) undergoing knee arthroplasty were included in this systematic review and meta-analysis comparing robot-assisted knee arthroplasty (RA-TKA or RA-UKA) vs. conventional knee arthroplasty techniques. Pooled outcomes of interest included range of motion (ROM) and pain measured by the visual analogue scale (VAS). The pooled analysis showed no significant difference in ROM or VAS pain scores between robotic and conventional procedures. Overall, the findings suggest that robot-assisted knee arthroplasty provides comparable clinical outcomes to conventional methods, indicating that robotic approaches may be a viable alternative depending on surgical expertise and patient characteristics.
