Clinical Question: To compare outcomes among patients assessed at different time points after ACLR, determine strength gains indicative of improvements in subjective function, and determine the amount of time necessary to achieve meaningful strength gains. 

Bottom Line:  Subjective IKDC and quad function increased when tested at later time points. Approximately 2 months is needed to observe clinically meaningful improvements BETWEEN assessment time points. 
Points to Consider: Cross-sectional/case control (Level 3). 293 patients participated s/p ACLR. Participants were stratified on the month of their evaluation following ACLR: 5-6 mos, 6-7 mos, 7-8 mos and 8-9 mos. IKDC subjective form, knee extensor & flexor torque and symmetry were assessed with an isokinetic dynamometer and compared.
