What is the second line of treatment if the rotator cuff pain and weakness persist?

If there is a thickened acromion or acromial bone spur causing impingement, it can be removed with a burr using arthroscopic visualization. This procedure can often be performed on an outpatient basis, and at the same time, any minor damage and fraying to the rotator cuff tendon and scarred bursal tissue can be removed. Often this will completely cure the impingement and prevent progressive rotator cuff injury
