Before qualifying for surgery, shoulder pain should be thoroughly diagnosed by an orthopedist. Clinical tests and imaging tests allow to determine the severity of degenerative changes and / or the extent of shoulder injuries. Surgery is performed if the identified changes hinder sports or professional activity, do not undergo rehabilitation treatment, or a shoulder injury can only be treated surgically. When planning treatment, the doctor also takes into account the patient's expectations regarding the level of shoulder fitness and readiness to undertake rehabilitation after the procedure.
