Transglenoid Fixation Technique for Arthroscopic Subscapularis Augmentation Using an Adjustable-Length Loop Cortical...

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Shoulder Biomechanics

Background:

• Anterior shoulder instability management is debated.
• The Latarjet procedure has drawbacks and may be overtreatment for some patients.
• Arthroscopic subscapularis augmentation is an alternative surgical option.

Purpose of the Study:

• To describe a novel technical variation of arthroscopic subscapularis augmentation.
• To detail the use of a graft for tenodesis of the upper subscapularis tendon.
• To introduce transglenoid fixation-immobilization with knotless TightRope devices as an alternative to anchors.

Main Methods:

• A modified arthroscopic subscapularis augmentation technique was developed.
• The technique involves tenodesis of the upper third of the subscapularis tendon with a graft.
• Transglenoid fixation-immobilization was achieved using two knotless TightRope devices.

Main Results:

• The described technique offers a variation in arthroscopic management for anterior shoulder instability.
• Utilizes a graft for subscapularis tendon tenodesis.
• Employs knotless TightRope devices for fixation, potentially simplifying the procedure.

Conclusions:

• This modified arthroscopic subscapularis augmentation provides a new surgical option.
• The technique may be suitable for patients with moderate glenoid bone loss.
• Further studies are needed to evaluate clinical outcomes and recurrence rates compared to existing methods.
