Abstract

Twenty-five patients who underwent unicompartmental knee arthroplasty (UKA) were analyzed 24 months after surgery. Mean age at surgery was 64.2 years (SD: 3.3). Mean Knee Osteoarthritis Outcome Score (KOOS) and International Knee Documentation Committee (IKDC) subjective score significantly improved at follow-up (p < 0.001). A significant difference in the Visual Analog Scale (VAS) score (p < 0.001) was reported. Median Tegner activity level score increased from 5.0 to 6.0 (p < 0.001). 96% of patients resumed sports or physical activity. UKA enables a significant percentage of moderately active patients suffering from unicompartmental knee osteoarthritis to resume daily and recreational practice at the same or higher intensity as before. 2026 Legnani, Macchi, Borgo and Ventura.
