Figure 2. Forest Plot of Factors Associated With Physical Function at 12 mo.

BMI indicates body mass index; K-L, Kellgren-Lawrence; NA, not applicable; OA, osteoarthritis. Direction of correlation: increased values of factors correlate with better postoperative function for all factors except dichotomous values (ie, cruciate retaining, male sex, patella resurfaced, and multicompartment OA), for which presence of factor correlates with better postoperative function.
