Number of knees with worsening pain/Total knees

Adjusted for age, sex, race, BMI, clinic site, gait speed, and static HKA alignment

^†

Clinically Important Worsening is an increase of at least 2 in WOMAC score for knees with a baseline score of 0 or an increase of at least 20% for knees with WOMAC scores greater than 0 (16, 17).
