(English) Episode 204-ACL Recovery Goals Depend on Graft and Age

This research study evaluates which thigh-muscle performance metrics most accurately predict a patient's self-reported recovery within nine months of ACL reconstruction. By analyzing data from 256 participants, the authors found that quadriceps strength symmetry serves as the most effective indicator of normal knee function. The study highlights that clinically significant cutoffs for recovery are not universal but vary based on the patient's age and the specific graft type used during surgery. Additionally, hamstrings strength and quadriceps power were identified as secondary but vital predictors of a successful outcome. Ultimately, these findings encourage clinicians to move beyond simple timelines and use individualized strength benchmarks to guide rehabilitation and return-to-sport decisions.(Sherman D, Birchmeier T, Kuenze CM, Garrison C, Hannon J, Bothwell J, et al.
