Shoulder problem Normally these tendons transmit the force of muscles originating on the shoulder Blade (scapula) to the arm providing motion and stability. The most commonly affected tendon is that of the supraspinatus muscle. Defects in the rotator cuff can come from an injury (cuff tear) or from degeneration (cuff wear). The degree to which a tendon is reparable depends on its quantity and quality. Degenerated tendons are often frail and retracted and may not be amenable to repair. Individuals that are elderly, smokers, or those having had cortisone injections often have weaker tendon tissue that fails without a significant injury. By
Rotator cuff tear postoperative pain or pain medication use apparently are not seen between arthroscopic- and open-surgery. Even for full-thickness rotator cuff tears, conservative care (i.e., nonsurgical treatment) outcomes are usually reasonably good. However, many people still have disability and pain despite nonsurgical therapies. For massive tears of the rotator cuff, surgery has shown durable outcomes on 10-year follow-up. However, the same study demonstrated ongoing and progressive fatty atrophy and repeat tears of the rotator cuff. MRI evidence of fatty atrophy in the rotator cuff prior to surgery is predicative of a poor surgical outcome. If the rotator cuff is completely torn, surgery
