The purpose of this study is to clarify the long-term results of conservative treatment cases of the rotator cuff tears. Participants are 100 patients (103 shoulders) who were diagnosed as rotator cuff tear with magnetic resonance image or arthrography in our institution from 1996 to 1999. We could follow up 65 shoulders by direct examination or telephone survey, and we could evaluate 43 shoulders, because we excluded 11 shoulders which were dead, 10 shoulders which were impossible to evaluate due to dementia and 1 shoulder which received shoulder trauma. The average age of 43 shoulders at the time of the diagnosis was 62 years old, and their average follow-up period was 13 years. We used the pain score (30 points) and the activities of daily life score (10 points) of Japan Orthopaedic Association Shoulder scoring system. The average of the pain score was 25.4 points, and the patients with no pain were 56%, and the patients with only slight pain were 33%. The average score of activities of daily life was 9.4 points, and patients with no disturbance in daily life were 72%. The patients which were less than 20 points / 40 points (pain score 30 points + activity of daily life score 10 points) were significantly younger in comparison with the others. In conclusion, in conservative treatment cases of the rotator cuff tears after 13 years from diagnosis, about 90% of patients had zero or only slight pain and about 70% had no disturbance in activity of daily life. However, the younger patients tended to have significant pain or disorder in daily life over 10 years later.
