Comparison of Monthly Sports Participation Between Nonsurgically and Surgically Treated Patients Over Two Postoperative Years^*

	Crude Odds Ratio† (95% CI), P Value	Propensity-Score-Adjusted Odds Ratio† (95% CI), P Value
Participation in level-I sports
1st year of follow-up	1.45 (0.76-2.76), 0.265	0.73 (0.38-1.41), 0.350
2nd year of follow-up	2.78 (1.40-5.52), 0.004	1.30 (0.61-2.78), 0.497
Participation in level-II sports
1st year of follow-up	0.23 (0.14-0.38), <0.001	0.28 (0.16-0.49), <0.001
2nd year of follow-up	0.65 (0.37-1.14), 0.131	0.88 (0.47-1.34), 0.689
Participation in level-III sports	0.47 (0.21-1.05), 0.065	0.41 (0.18-0.94), 0.034

^*Sports participation was recorded from the six-week test to the two-year test in the nonsurgical group and from the ACL reconstruction to the two-year test in the surgical group.

^†An odds ratio of >1 indicates a higher number of patients treated with ACL reconstruction participating in sports.
