Clinical Question: What is the utility of BFR long after ACLR?

Bottom Line: Rectus femoris and vastus lateralis thickness and knee extensor strength in the involved leg increased by 11%, 10% and 20%, respectively (all P< .01).

Points to consider: ACLR participants were (5 +/- 2 years post-op) and performed home BFR exercises for 25-minutes, 5x/week for 4 weeks. Baseline and post-training symmetry (between involved and uninvolved legs) were compared to uninjured controls. 

Takeaway: Implementation of BFR exercise can still be beneficial multiple years following ACLR.
