Arthroscopic repair of an isolated teres minor tear

Case: Isolated avulsion of the teres minor tendon is exceedingly uncommon and, to our knowledge, the presentation and arthroscopic repair of this type of injury have not been described. Known musculotendinous avulsions about the shoulder frequently involve the supraspinatus, long head of the biceps, and pectoralis major. Conclusion: We present the case of a patient with an isolated teres minor avulsion and an otherwise intact rotator cuff. The patient underwent successful arthroscopic repair and rehabilitation, allowing for a return to the pre-injury level of function.
