Senorski EH, et al. - Researchers ascertained the preoperative predictors of long-term acceptable knee function and the development of osteoarthritis (OA) in long-term follow-up after anterior cruciate ligament (ACL) reconstruction. An increased risk of having OA 16 years after reconstruction was seen in the patients who were older at the time of ACL reconstruction and had waited >1 year between the injury and reconstruction. Acceptable long-term knee function was reported by 1 in 2 patients, however, no risk factor for poorer subjective knee function was identified. Increased odds of reporting an acceptable long-term knee function was seen in the patients who had a minor concomitant injury and increased preoperative anteroposterior knee laxity.
