The posterior-medial portal.

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Shoulder Joint Anatomy

Background:

• Posterior superior labrum tears often require surgical repair.
• Traditional arthroscopic repair techniques can face challenges in accessing the posterior-superior labrum.
• Biceps tendon attachment proximity can complicate posterior labral access.

Purpose of the Study:

• To describe a novel arthroscopic technique for repairing the posterior superior labrum.
• To enhance visualization and access to the posterior-superior labrum during arthroscopic surgery.
• To establish a safe and effective posterior-medial portal for labral repair.

Main Methods:

• Establishment of a lateralized posterior arthroscopic viewing portal.
• Creation of a posterior-medial portal for suture retrieval.
• Placement of a suture anchor posterior to the biceps attachment via an anterior portal.
• Utilization of a suture retriever through the posterior-medial portal.
• Repair of the labrum using simple or mattress sutures retrieved and tied via the anterior-superior portal.

Main Results:

• The described technique allows for improved visualization of the posterior-superior labrum.
• A posterior-medial portal can be safely established with careful attention to technique.
• The method facilitates effective suture anchor placement and labral repair.
• Sutures can be successfully retrieved and tied through the anterior-superior portal.

Conclusions:

• This arthroscopic approach provides a viable method for posterior superior labrum repair.
• The technique offers a safe and effective means to address posterior labral pathology.
• Improved portal placement enhances surgical outcomes for posterior superior labral tears.
