Abstract

This article analyzes the factors that influence the return to sport (RTS) and the risk and rates of reinjury after a previous primary anterior cruciate ligament reconstruction (ACLR). The incidence of RTS after ACLR ranges from 71% to 83%. With regard to factors influencing RTS, a limb symmetry index score of 90 or more doubles the probability of RTS and triples it when the International Knee Documentation Committee (IKDC) score is 95 or more, regardless of age. Other factors identified to be predictive of RTS at 12 months include complete rehabilitation, age ≤25, and higher IKDC scores. The incidence of reinjury after ACLR ranges from 1.5% to 37.5% (between 9% and 29% in most publications). It has been reported that 1 in 5 patients suffers reinjury to either knee, and that male patients are more likely to reinjure after ACLR. The highest rate of ACLR reinjury occurs in younger men (
