Does arthroscopic rotator cuff repair actually heal? Anatomic evaluation with magnetic resonance arthrography at minimum 2 years follow-up.

Purpose: The goal of this series was to evaluate the clinical and anatomical outcomes of all-arthroscopic rotator cuff tears repair at a mid-term follow-up, using MR arthrography in order to assess tendon-to-bone healing.

Materials And Methods: This retrospective study included 29 patients (31 shoulders) presenting, according to Cofield classification, a small or moderate-sized supraspinatus full thickness tear with (7/31) or without (24/31) infraspinatus extension. The mean size of the tear was 2.

Anatomic risks of shoulder arthroscopy portals: anatomic cadaveric study of 12 portals.

Purpose: The purpose of this anatomic cadaveric study was to determine with trocars in situ the relationships of 12 shoulder arthroscopic portals frequently used with the adjacent musculotendinous and neurovascular structures.

Methods: Twelve shoulders of embalmed cadavers installed in a beach-chair position were dissected. Twelve different portals were established by using their authors' description: posterior "soft point," central posterior, anterior central, anterior inferior, anterior superior, 5 o'clock portal, Neviaser, superolateral, transrotator cuff approach, Port of Wilmington, anterolateral, and posterolateral.
