Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 100 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Care Provider)
Primary Purpose: Treatment
Official Title: Blood Flow Restriction Therapy in Patellofemoral Pain Syndrome
Estimated Study Start Date : February 2019
Estimated Primary Completion Date : November 2019
Estimated Study Completion Date : November 2019

Arm Intervention/treatment
Experimental: Patients with Patellopain syndrome with Cuff
Patient will be prescribed to 6 weeks of physical therapy with a cuff around the affected leg during exercises
Procedure: Personalized Tourniquet System for Blood Flow Restriction
Patients will be receiving blood flow restriction therapy with a pressure cuff

Placebo Comparator: Patients with Patellopain syndrome with Placebo Cuff Procedure: Placebo
Patients will be receiving blood flow restriction therapy with a pressure cuff set to a placebo pressure setting.

Primary Outcome Measures :
  1. Increase in Muscle Mass Measured by Biodex [ Time Frame: 6 Weeks ]
    Biodex dynamometer is used under standard of care to measure the extensor strength of both legs and have bilateral thigh circumference measured

  2. Decrease in Pain measured by Visual Analog Scale (VAS) [ Time Frame: 6 Weeks ]
    100-mm horizontal line anchored at one end with the words "no pain" and at the other end with the words "worst pain imaginable."
