Arthroscopic Biological Augmentation for Massive Rotator Cuff Tears: The Biceps-Cuff-Bursa Composite Repair

Area of Science:

• Orthopedic Surgery
• Regenerative Medicine
• Biomaterials

Background:

• Massive rotator cuff tears present surgical challenges due to tendon retraction and atrophy, leading to high retear rates.
• Existing augmentation methods include synthetic patches and bioinductive scaffolds, with limited success in structurally compromised tendons.
• The subacromial bursa possesses stem cell potential, and the long biceps tendon has been used in other reconstructive procedures.

Purpose of the Study:

• To describe a novel surgical technique combining long biceps tendon and subacromial bursa autografts for rotator cuff repair augmentation.
• To evaluate the feasibility and potential benefits of this combined biological graft approach.

Main Methods:

• A "traction and tenodesis" technique harvests the long biceps tendon (LBT) autograft.
• A vasculature-preserved subacromial bursa is mobilized as a "vascular bursal duvet".
• All-suture anchors minimize tuberosity defects; the bursa and cuff are repaired as a composite unit.

Main Results:

• The described technique allows for the combined use of LBT and subacromial bursa as biological autografts.
• This approach offers potential for both structural and regenerative augmentation of rotator cuff repairs.
• Autografts are readily accessible with no additional cost.

Conclusions:

• The combined use of long biceps tendon and subacromial bursa autografts represents a promising, cost-effective strategy for augmenting rotator cuff repair.
• This technique addresses the challenges of massive tears by providing biological scaffolding and enhancing healing potential.
• Further investigation is warranted to assess clinical outcomes and long-term efficacy.
