Coordination of the Lower Limbs of Soccer Players after Anterior Cruciate Ligament Reconstruction with Allograft and Autograft during Landing

Objectives: Quantitative biomechanical tests, along with physical assessment, may be useful tounderstand kinematics associated with graft types in anterior cruciate ligament surgery, particularly inindividuals aiming for a safe return to sport.Methods: Sixty male soccer players in three groups participated in this study. Three equal groups of healthy, autotransplanted and allotransplanted participants, matched for age, gender, activity level and functional status, landedwith one foot on a force plate. Their kinematic information was recorded by the motion analyzer and used to describecoordination the variability by measuring coupling angles using vector coding.Results: The coordination variability of the allograft group in the surgical limb was significantly greater than that ofthe healthy group at least ۹ months after the reconstructive surgery of the ACL and at the stage of return to sports,(F (۶, ۳۵) = ۲.۷۹, p = ۰.۰۲۵; Wilk's Λ = ۰.۶۷۶, partial η۲ = ۰.۳۲). The coordination pattern in the surgical and healthylimbs of the surgical groups also differed from that of the healthy people, which was more pronounced in the allograftgroup, (F (۶, ۳۵) = ۲.۶۱, p = ۰.۰۳۴; Wilk's Λ = ۰.۶۹۰, partial η۲ = ۰.۳۱).Conclusion: These results show that the allograft group has a different coordination variability at return to sportthan the healthy group, so they may need more time for excessive training and competition. Level of evidence: II
