Can one do pull-ups after anterior cruciate ligament injury?

Hello,

Welcome to icliniq.com.

Sure the X-ray looks kind of AC joint separation due to the ligament injury. With the image, the injury looks between grade II or III. I will advise you to take the call for the MRI shoulder to focus on the AC (acromio clavicular) joint. This will help us understand the extent of the ligament injury as from outside examining will be a little tough.

Once we get the MRI, we will be able to see the internal soft tissues including the ligaments and muscles. Post which your query of doing pull-up can be answered. But for now, do not do any movements of the shoulder and let all the healing to occur. Meantime, please take the MRI so we can judge the trauma to the fibers of the ligament.

Once we get hold of the MRI we can plan the exercise prescription if the ligament is not completely torn and in future can prepare you for the pull-ups. In case if found complete tear then can advise for the next course of action. I will wait for your response.
