Anterior Cruciate Ligament (ACL)

  • Predictors of Recovery Following Anterior Cruciate Ligament Reconstruction

    It is expected that after 6-9 months of rehabilitation following anterior cruciate ligament (ACL) reconstruction, individuals will be prepared to return to their previous activities. However, not everyone progress at the same rate and some people have trouble regaining their prior function. The purpose of this study is to identify factors related to successful recovery from surgery.

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

    What will you do?
    You will fill out questionnaires. We will measure your level of pain, swelling, motion, strength and function. Function will be measured with motion analysis technology including cameras and sensors. Depending on how long it has been since surgery, we will evaluate how you walk, squat, run and land.
    Testing will take approximately an hour. We will test you every 4 weeks for 6 months to assess your progress. 

    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. 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 an hour. We will only test you one time.
