Purpose: Many studies report a high primary success rate of ACL reconstruction (ACLR), with an increased risk of decline in knee performance correlating with the time passed since surgery. Only one study has compared male soccer players after ACLR to a matched control group of uninjured players in terms of their return to sport and performance. The purpose of this cross-sectional case-control study was to determine the knee performance between soccer players after ACLR and control group matched by age, sex, and professional experience. Methods: All the male professional soccer players aged 18–36 years at the time of injury, who sustained an ACL tear while playing league soccer in Poland between January 2008 and December 2011 were contacted and compared with age and experience-matched healthy control group selected from professional football players. KOOS, IKDC-2000, Lysholm and SF-36 scales were used for comparison. Results: The average follow-up was 7.9 years (range 6–9 years). The ACL-injured soccer players scored significantly lower in IKDC and Lysholm scores compared with the reference group but still were classified as normal knee function in both scales. In all five dimensions of the KOOS and subscales of SF-36 no apparent differences were noted. In all scales in the study group, no correlation was observed between the player’s age and follow-up time after ACLR. Conclusion: After ACL reconstruction and successful return to professional sport, knee function is as good as uninjured team members in the midterm follow-up. Level of evidence: III

Background and Objectives: Patellofemoral Arthropathy (PFA) is the most common knee disorder in runners and various factors can lead to the development of its symptoms. It has been proposed that frontal plane motions of the hip and knee can raise the dynamic quadriceps angle during functional tasks. The aim of this study was to evaluate frontal plane acting hip muscle flexibility and strength differences in male sprinter runners with unilateral PFA. Methods: A total of 38 male runners complaining of peripatellar pain or showing positive unilateral patellar grind test, assigned to the normal and sound legs, and 20 matched control groups were compared in this case-control study. Participants’ hip abductor and adductor muscles strength and their flexibility were evaluated through a hand-held dynamometer and 2D motion analysis tracker software. To measure the strength, participants were positioned side-lying position, performing abduction and adduction, while a dynamometer was placed on the lateral and medial femoral epicondyle. Active and passive abduction and adduction range of motion were recorded via a camera in the supine position and the film was analyzed by the software. Results: Abductor muscle strength and abduction-to-adduction ratio on the involved side were significantly lower than the uninvolved side (P=0.029, P=0.008, d=-0.388, d=-0.459), while greater adduction and lower abduction to adduction ratio were found in the control group (P<0.001, F=3.599). Also, lesser passive abduction and active adduction range of motion were found in the control group on both sides (P<0.001, F=2.792, F=8.979). Conclusion: Strength changes of the involved side compared with uninvolved side and less flexible side, but more probably inhibited and stronger adductors in the control group may suggest impaired muscular interaction based on frontal plane muscles torque/length curve function in unilateral PFA. Changes in the strength of the involved side compared to the healthy side and the adductor muscles with more flexibility and strength but more inhibited by the abductor’s muscles in the control group could indicate.
