Most active patients return to the same or higher level of daily and recreational practice following unicompartmental knee arthroplasty

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.
