Cox regression analysis for the risk of anterior cruciate ligament revision for lateral collateral ligament injury

Groups compared	Hazard ratio unadjusted	p value	Hazard ratio adjusted*	p value adjusted*
Isolated ACL vs concomitant LCL (any treatment)	1.18 (0.49–2.84)	n.s	1.11 (0.46–2.67)	n.s
Isolated ACL vs ACL + non-surgically-treated LCL	1.04 (0.39–2.78)	n.s	1.00 (0.37–2.67)	n.s
Isolated ACL vs ACL + LCL suture repair	0.60 (0.08–4.29)	n.s	0.56 (0.08–4.01)	n.s
Isolated ACL vs ACL + LCL reconstruction	22088.8 (0.00–◊)	n.s	18914.6 (0.00–◊)	n.s

ACL anterior cruciate ligament, LCL lateral collateral ligament, n.s non-significant

*Adjusted for patient sex, graft diameter and concomitant cartilage injury

^◊No events in one of the groups means that the hazard ratio cannot be estimated
