Summary

This trial finds that for patients with medial compartment osteoarthritis, UKA results in better function and less pain than TKA.

Who is the study for?
This trial is for people with severe osteoarthritis in one part of the knee, who can bend their knee well and don't have too much leg curvature. It's not for those who are very overweight or have diabetes that isn't well-controlled, serious kidney or liver disease, a history of drug abuse, inflammatory arthritis, or past infections in the joint.
What is being tested?
The study compares two surgical procedures for knee osteoarthritis: unicompartmental (partial) and total knee replacement. Patients will be randomly assigned to receive one of these surgeries to see which is better at improving outcomes.
What are the potential side effects?
Possible side effects include pain at the surgery site, swelling, infection risk increase after surgery, blood clots in legs or lungs (thromboembolism), stiffness in the knee joint and problems with implant like loosening over time.
