  • TekScan data are reported as mean and SD as normally distributed data. Varus/valgus measures are reported as median and IQR owing to skewed data. Hop time and p values reported to three decimal places otherwise.

  • ACL, anterior cruciate ligament; P, pressure measured in Newtons (N); VV, varus/valgus deviation from neutral reported in degrees.
