To determine with ultrasound the probability that a rotator cuff tear will enlarge over time. To determine if symptom progression correlates with enlargement of the rotator cuff tear and/or degenerative changes on radiographs.

The study subjects will have repeat physical exam, ultrasound and radiographic examinations.
