  • AB Purpose: There is scarcity of information on the long-term adaptations in lower limb biomechanics during game-specific movements after anterior cruciate ligament (ACL) reconstruction. Particularly, variables such as knee abduction moments and transverse plane knee motion have not been studied during a game-specific landing and cutting task after ACL reconstruction. The purpose of this study was to compare the hip and knee mechanics between the ACL-reconstructed (ACLr) group and a healthy control group. Methods: Thirty-eight reconstructed athletes (18 ACLr, 18 control) participated in the study. Three-dimensional hip, knee, and ankle angles were calculated during a maximal drop jump land from a 0.30-m box and unanticipated cutting task at 45[degrees]. Results: During the landing phase, ACLr participants had increased hip flexion (P < 0.003) and transverse plane knee range of motion (P = 0.027). During the cutting phase, the ACLr participant's previously injured limb had increased internal knee abduction moment compared with that of the control group (P = 0.032). No significant differences were reported between the previously injured and contralateral uninjured limb. Conclusions: Previously injured participants demonstrated higher knee abduction moment and transverse plane range of motion when compared with those of control participants during a game-specific landing and cutting task.
