Arthroscopic Bioinductive Collagen Scaffold Augmentation in High-Risk Posterosuperior Rotator Cuff Tears: Clinical...

Area of Science:

• Orthopedic Surgery
• Biomaterials Science
• Regenerative Medicine

Background:

• Bioinductive bovine collagen implants (BCI) are utilized to improve tendon biology and tissue regeneration in rotator cuff (RC) repairs.
• High-risk rotator cuff tears require advanced augmentation strategies to prevent retears and enhance healing.

Purpose of the Study:

• To evaluate the clinical and radiological outcomes of arthroscopic posterosuperior rotator cuff (psRC) repair augmented with BCI.
• To assess the efficacy of BCI in patients with full-thickness psRC tears at high risk of failure.

Main Methods:

• A case series of 30 high-risk psRC tear patients undergoing arthroscopic repair with BCI augmentation.
• Clinical outcomes assessed via Subjective Shoulder Value (SSV), American Shoulder and Elbow Surgeons (ASES) score, and Constant score at 6 and 12 months.
• Tendon integrity evaluated using Sugaya classification and MRI at 12 months postoperatively.

Main Results:

• At 12 months, MRI showed complete tendon healing in 56.7% of patients.
• Significant improvements observed in SSV, ASES, and Constant scores, exceeding minimally clinically important differences.
• Low complication rates, with 6.7% developing shoulder stiffness and 3.3% requiring revision surgery.

Conclusions:

• BCI augmentation demonstrates promising short-term clinical and radiological outcomes for high-risk psRC tears.
• Patients experienced significant improvements in shoulder pain and function.
• Satisfactory tendon healing rates were observed post-augmentation.
