Stiff landings in vertical drop jump test associated with increased risk of ACL injury
April 25, 2017

Read the Perspective from Darren L. Johnson, MD

Young female basketball and floorball players who demonstrated stiff landings with less knee flexion and greater vertical ground-reaction force in a vertical drop jump test had a greater risk of ACL injury, according to results.

Mari Leppänen , MSc, and colleagues analyzed knee valgus angles at initial contact, peak knee abduction moment, knee flexion angle at initial contact, peak knee flexion angle, peak vertical ground-reaction force and medial knee displacement in 171 female basketball and floorball players who participated in a vertical drop jump test using 3-D motion analysis. Researchers recorded all new ACL injuries, as well as match and training exposure for 1 year to 3 years.
