The rotator cuff is an area that may have some long term complications, or sequelae, after surgery has been performed. First, there is a risk of dislodgement or loosening of the internal fixation device. This is often seen when the patient does not pay attention to the protection of the shoulder joint after such surgery, and does excessive activities at an early stage. This may cause the relevant internal fixation, such as rivets, to loosen or fall out, which in turn may cause the patient to have significant pain in the shoulder and a decrease in muscle strength. Secondly, there may be a decrease in muscle strength, which is often seen when the patient does not exercise the shoulder under the guidance of the doctor in a timely manner after such surgery. This may lead to muscle atrophy due to prolonged braking, which may result in a decrease in strength. Third, there is a possibility of long-term pain. Some patients may continue to have pain around the shoulder joint even after surgery because the injury is too severe. Fourthly, there may be some limitation of activity. This is also due to the fact that the patient did not do the functional exercises in time after the surgery, which led to serious adhesions in the shoulder, and then there will be a decrease in mobility. Fifthly, some patients may also have a strange noise during the activity.
