Partial knee replacement may lead to higher patient satisfaction compared with total knee arthroplasty (TKA) in appropriately selected patients. Findings indicate that individuals undergoing unicompartmental knee arthroplasty reported greater satisfaction, potentially due to preservation of native knee structures, more natural joint kinematics, and faster functional recovery. Partial knee replacement is typically performed in patients with disease confined to a single compartment, allowing for a less invasive procedure and retention of key ligaments. These characteristics may contribute to improved perception of knee function and overall postoperative experience. The results highlight the importance of careful patient selection when considering partial versus total knee replacement, emphasizing that tailored surgical approaches may enhance satisfaction and functional outcomes.
