Description
Tsz-Lung Choi and co-authors compare three ways of performing knee replacement: the classic manual technique, a robotic arm's guidance, and pressure sensors that report joint loads live. Their study appeared in 2026. The cohort covered 173 knees in 139 patients at one center, split unevenly among the three methods. Pain, motion range, and function scores were compared after adjusting for starting state, age, sex, and body size.
After strict correction for multiple testing, no outcome separated the three groups convincingly. The authors also probed whether starting severity changed the ranking, and found no firm pattern. They counsel that, on patient-felt outcomes at least, the expensive guidance tools have yet to prove they beat a good surgeon's hands.
