Recent research on ACLR warrants a reexamination of clinicians\u2019 current rehabilitation practices to optimize the strikingly variable clinical outcomes after ACLR and return to sport.

Commonly held clinical beliefs regarding rehabilitation after ACL injury must be challenged by the latest research to improve patient outcomes and decrease the risk of reinjury. Key updates to the practice guidelines include the use of frequent and accurate quadriceps strength testing, delayed return-to-sport timeline, immediate use of open kinetic chain exercise, criterion-based progressions for running, sprinting, plyometrics, agility, cutting\/pivoting, return to competition, and the inclusion of a secondary prevention program after return to
