Minimal clinically important differences and substantial clinical benefits for Knee Society Scores

ConclusionDifferent methods for MCID calculation lead to different results. With the use of ROC curve analysis, patients with an improvement of at least 9 points for KSS-knee and 10 points for KSS-function scores experience a clinically important change, whereas those who have at least an improvement of 40 points for KSS-knee and 39 points for KSS-function scores experience a substantial clinical benefit. These findings can ensure clinical improvement from the patient ’s perspective and also aid in interpreting results from clinical studies.Level of evidenceIII.
