[Suture technique for rotator cuff tears' repair under arthroscopic]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Arthroscopic rotator cuff repair is standard for tears.
• Various suture techniques exist, but an ideal method remains elusive.
• Single-row and double-row techniques are common, with double-row offering superior biomechanical strength.

Purpose of the Study:

• To compare biomechanical properties and clinical outcomes of different rotator cuff repair techniques.
• To identify factors influencing the choice of optimal surgical technique.

Main Methods:

• Review of biomechanical properties of single-row, double-row, and transosseous tunnel suture techniques.
• Analysis of clinical trial data on healing rates and functional scores.
• Consideration of operative complexity and patient-specific factors.

Main Results:

• Double-row repair shows better biomechanical strength than single-row.
• Massive cuff stitch and modified Mason-Allen sutures offer the strongest biomechanical properties.
• Transosseous tunnel techniques enhance tendon-bone healing and are suitable for specific patient groups.
• Clinical outcomes show no significant difference between double-row and other techniques, despite improved healing rates.

Conclusions:

• The optimal rotator cuff repair technique requires individualized patient assessment.
• Factors include biomechanics, clinical outcomes, operative complexity, and patient condition.
• Technique selection should prioritize simplicity, speed, minimal trauma, and stable fixation.
