Total Versus Robotic Assisted Unicompartmental Knee Replacement

This study compares two types of knee replacement surgery for people with arthritis in the inner part of the knee: a full total knee replacement versus a smaller partial (unicompartmental) knee replacement assisted by a robotic system. Researchers want to determine which approach leads to better outcomes and recovery. You may be eligible if: - You are between 50 and 75 years old - You are scheduled for a knee replacement due to end-stage osteoarthritis in the inner (medial) compartment - Your knee ligaments (ACL and MCL) are intact - Your outer knee cartilage is healthy - Your knee deformity is correctable - Your anesthesia risk is low (ASA grade 1 or 2) You may NOT be eligible if: - Your knee has a varus deformity greater than 20 degrees or fixed flexion greater than 10 degrees - You have rheumatoid arthritis or another inflammatory joint disease - You have had previous knee surgery (other than arthroscopy) or septic arthritis - You are pregnant, breastfeeding, or planning pregnancy during the study - You have significant hip, foot, or spine problems Talk to your doctor to see if this trial is right for you.
