Take Home Message: Knees with a history of an anterior cruciate ligament injury are more likely to have osteoarthritis compared with a healthy contralateral knee but graft selection has no effect on long-term outcomes, such as osteoarthritis or knee functional outcomes.
An individual with a history of an acute knee injury, including anterior cruciate ligament (ACL) injury, is three to 6 six times more likely to have knee osteoarthritis (OA) than someone without a history of injury. Unfortunately, we lack a consensus on whether ACL reconstruction timing and graft selection affects the risk for knee OA. Therefore, the authors completed an extended follow up of a randomized clinical trial that compared quadrupled semitendinosus tendon and bone-patellar tendon-bone grafts.
