Preoperative Function Affects Ability to Achieve One-Year Minimum Clinically Important Difference for Patients Undergoing Total Knee Arthroplasty
Minimum clinically important difference (MCID) values are commonly used to measure treatment success for total knee arthroplasty (TKA). MCID values vary according to calculation methodology, and prior studies have shown that patient factors are associated with failure to achieve MCID thresholds. The purpose of this study was to determine if anchor-based 1-year Knee Injury and Osteoarthritis Outcome Score Joint Replacement (KOOS-JR) MCID values varied among patients undergoing TKA based on patient-specific factors.
