Data are mean (standard deviation) unless otherwise stated.

ACL=anterior cruciate ligament; MRI=magnetic resonance imaging; MCL=medial collateral ligament; LCL=lateral collateral ligament; IQR=interquartile range.

Tegner score evaluates sporting activity level (range 0-10, highest activity score 10).
