摘　　要：BACKGROUND Between 43%and 75%of patients who undergo primary anterior cruciate ligament(ACL)surgery return to sport activity.However,after a revision ACL reconstruction(ACLR)the rate of return to sports is variable.A few publications have reported returns to sports incidence between 56%to 100%after revision ACLR.AIM To determine return to sports and functional outcomes after a single-stage revision ACLR with a 5-year minimum follow-up at a single institution.METHODS All patients operated between 2010 and 2016 with a minimum 5 years of followup were included.Type of sport,intensity,frequency,expectation,time to return to sport and failure rate were recorded.Lysholm,Tegner and International Knee Documentation Committee forms were evaluated prior to the first ACLR surgery,at 6 mo after primary surgery and after revision ACLR at 5 years minimum of follow-up.Objective stability was tested with the knee arthrometer test(KT-1000 knee arthrometer,Medmetric Corp).RESULTS A total of 41 patients who underwent revision ACLR during that period of time were contacted and available for follow-up.Median patient age at time of revision was 29 years old[interquartile range(IQR):24.0-36.0],and 39(95.0%)were male.The median time from revision procedure to follow-up was 70 mo(IQR:58.0-81.0).Regarding return to sports,16(39.0%)were at the same level compared to preinjury period,and 25 patients(61.0%)returned at a lower level.Sixty-three percent categorized the sport as very important and 37.0%as important.One patient(2.4%)failed with a recurrent ACL torn.Mean preoperative Lysholm and(SD)16]and 50(SD 11),respectively.At follow-up,mean Lysholm and subjective International Knee Documentation Committee scores were 89(SD 8)and 82(SD 9)(P=0.0001).Mean Tegner score prior to primary ACLR was 6.7(SD 1.3),5.1(1.5 SD)prior to revision ACLR and 5.6(1.6 SD)at follow-up(P=0.0002).Overall,knee arthrometer test measurement showed an average of 6 mm(IQR:4.0-6.0)side-to-side difference of displacement prior to revision ACLR and 3mm(IQR:1.5-4.0)after re
