Sean's research interests are focused mainly on the knee, specifically ACL injuries and recovery. There are several ongoing studies involving recovery after ACL surgery including return to sports and activities. These patient reported outcome surveys are to investigate how to continually optimize patient outcomes in active patients who have suffered traumatic injuries like ACL tears.
