Background: With the aging society, musculoskeletal degenerative diseases are becoming a burden on Society, and rotator cuff disease is one of these degenerative diseases. The purpose of this study was to examine the incidence of Rotator cuff tear is the most common shoulder disease in patients with shoulder problems, at tertiary care hospital. Material and methods: A total of 700 patients examined. Ultrasonography on bilateral shoulders was performed in all the participants. Results: 165 subjects out of 700 participants (23.5%) had full-thickness rotator cuff tears. The prevalence of rotator cuff tear in each decade was 0% in the 20s to 40s, 14.7% in the 50s, 21.5% in the 60s, 31.2% in the 70s, and 32.6% in the 80s. Symptomatic rotator cuff tears accounted for 32.2% of all tears and asymptomatic tears for 67.8%. The prevalence of asymptomatic rotator cuff tears was one-half of all tears in the 50s, whereas it accounted for two-thirds of those over the age of 60. The prevalence of tear was significantly greater in male than in female in the 50s and 60s, but not in the 70s and 80s. Conclusion: The prevalence of rotator cuff tear in the general population was 21%, which increased with age. Asymptomatic tear was twice as common as symptomatic tear.
