Occupational Risk Factors and Clinical Impact of Rotator Cuff Disorders

Risk Factors Identified by the American Academy of Orthopaedic Surgeons

• Repetitive lifting and overhead activities significantly increase the risk of rotator cuff tears, which are the leading cause of shoulder‑related disability. 1, 2, 3
• Occupations that involve overhead work—such as painters and carpenters—have a higher likelihood of rotator cuff tears, reflecting biomechanical demands similar to those of mechanics. 1, 2

Pathophysiologic Mechanisms

• Chronic repetitive overhead work leads to degenerative rotator cuff tears through tendon wear rather than acute injury. 1, 2

Clinical Implications

• Over two‑thirds of patients undergoing rotator cuff repair are of working age, underscoring the importance of occupational prevention strategies. 1, 3
• Shoulder disease is the second most common cause of musculoskeletal disability among American adults (≈ 8% prevalence), with rotator cuff pathology being the primary contributor. 1, 3
