[Rotator cuff tear: correlation between ultrasound and arthroscopic findings].

Objective: To analyze the preoperative shoulder ultrasound (US) findings in patients with a diagnosis of rotator cuff (RC) tear and correlate them with the arthroscopic findings.

Methods: Retrospective analysis of a consecutive series of patients with a diagnosis of RC pathology in whom US was performed and who underwent surgery (shoulder arthroscopy). The US/arthroscopic findings were correlated with Fisher's and chi2 tests.
