^aBoldfaced values indicate statistical significance.

^bResults appear in parentheses for subgroup regression analyses of only patients who had KT side-to-side difference ≤4.0 mm (n = 42) using 4 independent variables: Tegner preinjury score, KT side-to-side difference, pivot grade, and age at operation.
