FRONTAL PLANE KNEE MOTION OF ACL-REPAIRED AND NON-INJURED FEMALES WHEN USING KNEE SAVERS

Abstract

Women are four to six times more likely to sustain ACL injuries compared to male counterparts. Few investigations have explored if ergonomic devices may alleviate the stress placed on the ACL during deep squatting. The purpose of the study was to determine if Knee Savers® (KS) influenced the frontal plane knee motion when previously-injured and healthy participants completed a squat. Female participants (ACLrepaired: n=10; healthy: n=10) completed a deep squat with and without KS using 2-D videography methods. Results indicated a greater medial motion of the patella in the frontal plane in the right leg of non-injured participants when compared to the ACLrepaired group (p = 0.04). When squatting with KS, the non-injured group experienced more frontal plane motion at the knee, compared to the ACL-repaired group.
