Orthopedics – Muscle Strength and Functional Performance After Medial Patellofemoral Ligament Reconstruction

Condition or Therapy:

Medial patellofemoral ligament


Orthopedics and Sports Medicine

What is the goal of this study?

The purpose of this study is to compare lower extremity strength and functional tests with patients who have had medial patellofemoral ligament (MPFL) reconstructed knee surgery with patient who have not.

Who can join the study?

Your child may take part in this study if:

  • Your child has patellar instability and are planned to have MPFL reconstruction surgery.
  • Your child has not injured their knee and actively participates in a minimum of 50 hours of pivoting and cutting sports per year in comparable sports.

What will happen if my child takes part in this study?

If you join the study, you would follow the standard of care for your type of injury. You will go through rehabilitation therapy after surgery, perform functional and strength tests and self-report your outcomes 6 months and 9 months after surgery as part of your clinical care. In this study, we will collect information from your medical record, such as demographic, surgical, functional, and outcome data. You will also fill out a questionnaire 12 months after surgery.
