Description
Replacing only the worn parts of a knee, rather than the whole joint, might keep patients more active, but proof has been thin. Sree Kanakala and co-authors tested that hope in 2026 inside a randomized trial, comparing robot-assisted partial replacement against full replacement. Patients wore a thigh sensor for a week before surgery and again at one and two years.
Activity rose after surgery in both groups, yet no measure of activity volume, intensity, or sitting time differed clearly between them. How active a patient was before surgery predicted later gains better than which operation they had. Self-reported outcomes also matched sensor readings only weakly. The authors say habits and behavior, not the procedure, drive later activity, and they call for larger, longer trials.
