While people with<unk> s may not have any noticeable symptoms, studies have shown that, those with age related<unk> s, over time 40% will have enlargement of the<unk>  over a five-year period. Of those whose<unk> s enlarge, 20% have no symptoms while 80% eventually develop symptoms. Most usually regain function and experience less pain following surgery. For some, however, the joint continues to hurt. Weakness and a limited range of motion also may persist. Those who report such symptoms frequently are diagnosed with failed<unk> <unk>  syndrome. There is no irrefutable evidence that<unk> <unk>  surgery benefits more than non-surgical management and a percentage of individuals never regain full range of motion after surgery. Arthroscopic procedures produce "satisfactory results" more than 90 percent of the time. However, 6-8 percent of patients have "incompetent"<unk> <unk> s because their repaired tendons either fail to heal or develop additional<unk> s. In some cases, persistent<unk> <unk>  type pain after surgery can be due to disease elsewhere. For example, cervical spine disease and can involve neck pain radiating into the shoulder. Suprascapular neuropathy, shoulder impingement, superior labral anterior-posterior (SLAP)<unk> s and arthritis can all mimic<unk> <unk>  disease and cause persistent pain that does not respond to<unk> <unk>  surgery.
