Clinical Trial Summary

A randomized controlled trial was conducted with 72 participants who had moderate knee osteoarthritis (Kellgren and Lawrence grade 2-3). The patients were randomly assigned to either the robotic-assisted or gyroscopic-assisted group. Baseline characteristics, including age, body mass index, length of stay, and estimated blood loss, were recorded. The primary outcome measure was the accuracy of the hip knee angle, measured by scannogram film preoperatively and postoperatively at 3 months. Secondary outcomes included functional outcomes (KOOS, Oxford knee score, EQ-5D-5L, range of motion) assessed preoperatively and postoperatively at 3 months, as well as at 6 months postoperatively.

Description:

Introduction: Primary total knee arthroplasty is considered the gold standard treatment for end-stage osteoarthritis of the knee. The primary objective of this surgical procedure is to restore mechanical alignment. At Siriraj Hospital, we employ technology to enhance the accuracy of our surgical procedures. The purpose of this study is to compare the accuracy of robotic-assisted surgery (ROSA) and gyroscope-based surgery in primary total knee arthroplasty.
