The purpose of this study was to evaluate ACL graft and contralateral rupture following ipsilateral or contralateral semitendinosus and gracilis (STG) graft harvest at follow\u2010up of a minimum 10 years post\u2010reconstruction in the treatment of a complete ACL tear.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients from a previous randomized trial were evaluated. The primary outcome measures were ipsilateral and contralateral reinjury as well as the International Knee Documentation Committee (IKDC) knee assessment form, the ACL Quality of Life questionnaire (ACL\u2010QoL) and the Tegner activity scale. Participants completed four different single\u2010leg hop tests and concentric knee flexion and extension strength were assessed on an isokinetic dynamometer.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the original 100 patients, 50 patients (41.3\u2009\u00b1\u20099.5 years of age, 31\u00a0males, 19 females) reported on re\u2010injury at 12.6\u2009\u00b1\u20091.4 years post\u2010operative. Thirty\u2010eight patients returned for full assessment and 12 responded by mail or phone survey. There were no differences between groups for graft rupture, contralateral injury, ACL\u2010QoL score, IKDC categorization, or anterior tibial translation, though both groups experienced a reduction in the Tegner Activity Scale from their preinjury scores. There was no difference in knee flexor and extensor isokinetic concentric strength, or single leg hop test performance. Knee flexor strength limb symmetry index was reduced when measured in the supine relative to the seated position in both groups, indicating persistent deficits in knee flexor strength when measured in the supine position.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Contralateral hamstring harvest does not put patients at an increased risk of a contralateral ACL tear and long\u2010term outcomes of ACL reconstruction do not differ based on the side of graft harvest.
