Table 2 Crude and adjusted differences in the KOOS Sport sub-scores of the MLKI group between baseline and 1-year follow-up and the impact of risk factors (gender, age, meniscus and cartilage injury)

	Crude (mean[95%CI]) n = 5093	Adjusted (mean[95%CI]) n = 5085	p-values
*Mean difference (Isolated ACL [controls])*	21.49 (20.73;22.30)	21.75 (20.20;23.29)	< 0.001
Mean difference (MLKI)	16.69 (12.88;20.50)	16.67 (12.79;20.59)	< 0.001
Mean difference (MLKI vs Isolated ACL)	4.81 (0.95;8.66)	5.06 (1.17;8.94)	0.01
Gender (female)		-0.50 (-2.02;1.02)	0.52
Age (year)		0.07 (0.001;0.15)	0.05
Meniscus injury (yes)		1.98 (0.44;3.53)	0.01
Cartilage injury (yes)		-1.26 (-2.81;0.30)	0.11

Regression model adjusted for gender, age, meniscus and cartilage injury. Data presented as mean (95%CI). p-values < 0.05 indicates if the variable influence on the adjusted mean difference
