The Kerlan-Jobe Orthopaedic Clinic Overhead Athlete Shoulder and Elbow (KJOC) questionnaire has been tested and is considered to be a valid and reliable tool. It measures the functional status of overhead throwing athletes. It measures several different components needed to return to play. So it is considered a good predictor of return-to-play.
Studies show that the results of the KJOC survey can be influenced by outside, independent variables. For example, the type of surgery, type of sutures used to repair the damaged soft tissues, and severity of injury (partial versus full-thickness tears) can also influence the final results.
Players with both a rotator cuff tear and a labral tear are less likely to return to full sports participation. The partial tear and small labral tear that you describe would not necessarily put you out of the running for a full return to the game. About 55 per cent of professional baseball players with this type of injury are able to return to their preinjury level of play. Results are less favorable when there is a full-thickness tear of the rotator cuff, especially if combined with a labral tear of any size.
Regaining normal kinematics (motion) of the shoulder after complex shoulder injuries can take quite a bit of time in rehab. There is a delicate balance needed between mobility (movement) and stability (keeping the shoulder in the socket during activity) required for an overhead throwing athlete.
Your health care/sports team (e.g., surgeon, physical therapist, coach, athletic trainer) are the best ones to advise you. The fact that you have taken the KJOC test and been given a favorable score suggests you are receiving some useful guidance to help in the decision-making process.
