Blood flow restrictive (BFR) therapy following MPFL or ACL reconstruction rehabilitation. Specific Aim 1: Test whether maintaining BFR cuff inflation or deflating between exercises results in greater quadriceps strength and functional outcomes after MPFL or ACL reconstruction. Hypothesis 1: Subjects in the deflate BFR protocol group will have significantly greater quadriceps strength, symmetric leg symmetry index on a battery of functional tests and PROs as compared to the non-deflate group. Specific Aim 2: Compare whether maintaining BFR cuff inflation or deflating between exercises results in reduced pain, improved exercise tolerance, and patient-reports outcomes (PRO) after MPFL or ACL reconstruction. Hypothesis 2: Subjects in the deflated BFR protocol group will report significantly less pain and greater exercise tolerance during exercise with significantly improved knee related PRO scores.
