Abstract
BACKGROUND: The patient-related factors for the perceived need for surgery for degenerative rotator cuff tears are not known. The purpose of this study is to examine patient- and tear-specific factors leading to surgery in newly painful degenerative rotator cuff tears. METHODS: Asymptomatic, degenerative rotator cuff tears were followed prospectively to identify the onset of pain and tear enlargement. Newly painful tears were continually monitored with a focus on identifying patient-specific (age, occupation, activity level) and tear-specific (tear type and size, tear progression, American Shoulder and Elbow Surgeons score, muscle degeneration) factors that are associated with surgical intervention. RESULTS: Forty-eight of 169 newly painful shoulders were eventually managed surgically. Factors associated with surgical treatment included younger age (P = .0004), pain development earlier in surveillance (P = .0002), a greater increase in pain (P = .0001), a decline in American Shoulder and Elbow Surgeons score (P < .0001), and a history of contralateral shoulder surgery (P = .0006). Eighty-five of the 169 tears (50%) enlarged either before or within 2 years of pain development. Neither tear type (P = .13), tear enlargement (P = .67) nor tear size (P = .51) was associated with surgery. Neither the severity of muscle degeneration, occupational status, hand dominance, Shoulder Activity Score, nor changes in RAND-12 mental or physical scales differed between groups. DISCUSSION: For newly painful rotator cuff tears, patient-specific factors such as younger age and prior surgery on the contralateral shoulder are more predictive of future surgery than tear-specific factors or changes in tear size over time.
