BFRT MPFL and ACL Reconstruction Rehab
Condition: Medial Patellar Femoral Ligament Reconstruction Rehabilitation; Anterior Cruciate Ligament Reconstruction Rehabilitation
Study type: Interventional

Summary: 
      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.
    

Detailed description: 
      Subjects will be aged 13-40 male or female patient following MPFL or ACL reconstruction.

      Baseline Assessment at PT Evaluation will included knee AROM and AAROM Heel slide with strap,
      Knee edema measured in cm difference Involved to Non-involved at supra and mid patellar
      levels, subjects ability to SLR Yes/No in brace, Patient reported outcome measure (PRO's) to
      include LEFS, Brief Resiliency scale, MPFL - Norwich Patellar instability, ACL 2000 IKDC
      Subjective Knee Evaluation Form questionnaires. Pain assessment to include current, minimal
      and maximal pain levels past 24 hours.

      Patient are randomized into 1 of 2 groups: Group 1 will deflate between BFR exercises, Group
      2 will not deflate between BFR exercises. Both groups will receive the same standard care
      same during their first 2 weeks of post-op rehabilitation. BFR will be added to their
      rehabilitation care starting at week 3 for 2x/week x 10. There are 4 core BFR exercises that
      will be progressed every 2 weeks.

      Final Assessment- Strength and Functional Testing at 24th visit or 12 weeks post-op (if
      missed appointments) to include bilateral Knee AROM and edema assessments, PRO's: LEFS, Brief
      Resiliency scale, MPFL Norwich Patellar instability, ACL 2000 IKDC Subjective Knee Evaluation
      Form, Functional assessment to include for involved adn uninvolved leg: Isometric Quad
      strength measurement at 90 degrees of knee flexion, Isometric Hip Abduction strength
      measurement, Y balance maximum anterior reach, Max reps 6" Forward step-down, max core
      strength assessments, and ability in-line jog.
