Résumé : |
Objectives The objective of this study was to determine whether Division I athletes following anterior cruciate ligament reconstruction (ACLR), and who are medically cleared to return to sport, demonstrate faulty knee mechanics during a change of direction maneuver, as evidenced by the presence of genu valgum on VICON® motion analysis system of 5° or greater. Study design Cross-sectional study. Setting University. Participants Ten Division I athletes performed a 90° change of direction movement on both the ACLR and unaffected limbs. Main outcome measures Knee mechanics were assessed using the VICON® motion analysis system. Knee position was analyzed in the frontal plane and peak genu valgum position was determined during the functional movement. Results Eight out of ten athletes (80%) demonstrated genu valgum ≥ 5° on the ACLR limb during a 90° cutting movement. Fourteen out of twenty (70%) of the knees assessed demonstrated genu valgum ≥ 5° during a 90° cutting movement. Conclusion Athletes who have fully returned to sport following an ACLR demonstrate substantial genu valgum during a cutting maneuver, which suggests an increased risk for future injury. These results show an increased need during ACL rehabilitation to focus on existing biomechanical deficits during sport-specific movements. |
