Primary outcomePrimary: Determine if BFR Changes Loss of LE Lean Muscle Mass — 8.97; 8.97; 8.37; 8.93 kg
Summary
The study is a prospective randomized control trial consisting of subjects requiring ACL reconstruction with BTB autograft. Subjects were randomly divided into two groups following their inclusion in the study. One group underwent the normal ACL rehab protocol as determined by the participating surgeons. The study group underwent normal ACL rehab modified by use of a tourniquet for blood flow restriction during selected exercises.
