It was hypothesized that intact ACL graft reduces the risk for increased OA development.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The cohort comprised 60 patients with a median follow-up 31 (range 28\u201333) years after ACL reconstruction.

Patients with ruptured ACL grafts had more medial tibiofemoral compartment OA than those with an intact ACL graft (<jats:italic>p<\/jats:italic>\u2009=\u20090.0003). OA was asymmetric in patients with ruptured ACL grafts with more OA in the medial than in the lateral tibiofemoral compartment (<jats:italic>p<\/jats:italic>\u2009=\u20090.013) and the patellofemoral compartment (<jats:italic>p<\/jats:italic>\u2009=\u20090.002). The distribution of OA between compartments was similar in patients with an intact ACL graft. KT-1000 values of anterior knee laxity were higher in patients with ruptured compared to those with intact ACL grafts (<jats:italic>p<\/jats:italic>\u2009=\u20090.012). Side-to-side comparisons of anterior knee laxity showed higher KT-1000 values in patients with ruptured ACL graft (<jats:italic>p<\/jats:italic>\u2009=\u20090.0003) and similar results in those with intact graft (<jats:italic>p<\/jats:italic>\u2009=\u20090.09).
