Probability of a Rotator Cuff Tear

Rotator cuff tears are extremely common, affecting approximately 22% of people by age 60 and over 50% by age 80, according to imaging studies. However, many tears are asymptomatic; only about one-third of people with rotator cuff tears on MRI actually experience pain or functional limitation.

There are two main types: acute tears (from a sudden injury such as a fall or heavy lifting) and degenerative tears (from gradual wear and aging). Degenerative tears are far more common and are associated with age, repetitive overhead activities (painting, carpentry, tennis, swimming), dominant arm, smoking, and family history. Overhead athletes and manual laborers are at highest risk.

Treatment depends on tear size, symptoms, and activity level. Physical therapy is the first-line treatment and is successful in about 75% of patients with partial tears or small full-thickness tears. Surgical repair (usually arthroscopic) is recommended for acute tears, large tears, and failures of conservative treatment. About 300,000 rotator cuff surgeries are performed annually in the US. Post-surgical recovery typically takes 4-6 months, with full strength returning at 9-12 months.
