One systematic review found that prevalence of rotator cuff abnormalities ranged from 9.7% in patients ages 20 years and younger to 62% in patients ages 80 years and older. The authors concluded that rotator cuff tears are a common feature of normal aging and are commonly asymptomatic.[7]Teunis T, Lubberts B, Reilly BT, et al.
