title: [Subscapularis tendon lesions. Anatomy, diagnosis and importance of arthroscopic treatment].
abstract: The subscapularis tendon is involved in up to 43% of arthroscopically treated rotator cuff lesions. Due to the close anatomic relationship, participation of the long head of the biceps and supraspinatus tendon is common. Subscapularis tendon lesions are often not primary diagnosed correctly. Using specific clinical tests and modern sectional imaging, the percentage of correct diagnoses can be increased. Convincing clinical results, advantages of minimally invasive surgery, and superior visualization compared to the open approach argue for arthroscopic treatment of subscapularis lesions. Awareness of the footprint allows anatomic reconstruction. In case of planned open treatment, arthroscopy should precede as particularly articular-sided lesions might be missed otherwise.
