Deformities associated with the suture-bridge technique for full-thickness rotator cuff tears

Area of Science:

• Orthopedic surgery
• Sports medicine
• Biomedical engineering

Background:

• Rotator cuff tears are common injuries.
• The suture-bridge technique is a widely used method for rotator cuff repair.
• Deformities can arise during the repair process, potentially affecting outcomes.

Purpose of the Study:

• To evaluate the incidence and causes of deformities associated with the suture-bridge technique in rotator cuff repair.
• To identify specific tear characteristics and surgical configurations linked to deformities.

Main Methods:

• Prospective review of 100 consecutive shoulders with full-thickness rotator cuff tears treated with the suture-bridge technique.
• Classification of surgical technique by suture anchor configuration (2x2, 3x2, 3x3).
• Arthroscopic assessment for marginal dog-ear and central bird-beak deformities.

Main Results:

• Dog-ear deformities occurred in 47% of cases, most frequently in large tears with 2x2 configurations.
• Bird-beak deformities occurred in 13% of cases, also most frequent in large tears with 2x2 configurations.
• Both deformities were significantly more common in large tears compared to medium tears and with 2x2 bridges compared to 3x2 bridges.

Conclusions:

• The incidence of deformities in rotator cuff repair using the suture-bridge technique is influenced by tear size and surgical configuration.
• Larger tears and simpler suture bridge configurations (2x2) are associated with a higher risk of dog-ear and bird-beak deformities.
• Individualized repair strategies, considering tear characteristics, are recommended to minimize deformities.
