Anterior Cruciate Ligament (ACL)

  • Assessing Movement in Individuals Following Anterior Cruciate Ligament Reconstruction

    Many athletes undergo anterior cruciate ligament (ACL) reconstructive surgery in hopes to return to their previous activities. Despite improvements in the research based rehabilitation programs over the past decade, there still remains a high re-injury rate of up to 25%. Re-injury is often attributed to the return to higher level athletic activities before the resolution of movement impairments. Knowing how well people move after surgery or injury helps physical therapists focus their treatment on areas that need attention. Measuring how a person performs different tasks (i.e. walking, squatting, running etc.) requires expensive equipment. This study is looking at how we can use newer, less expensive technology to evaluate movement, track progress and improve treatments.

    Have you had an ACL reconstruction?
    We are inviting individuals between the ages of 14 and 55 who have had surgery and who are participating in physical therapy.

    What will you do?
    You will fill out questionnaires. We will measure your swelling, motion, strength and function. Function will be measured with motion analysis technology including cameras and sensors. We will evaluate how you walk, squat, run and land.
    Testing will take approximately 1-2 hours. We may ask you to come back for testing to assess your progress in rehabilitation.

    Are you healthy with no previous knee surgery?
    We are inviting individuals between the ages of 14 and 55 who have not had previous knee surgeries to participate too. We will use your information to determine how well individuals are progressing after ACL reconstruction.

    What will you do?
    You will complete the same testing described above.
    Testing will take approximately 1-2 hours.
