[Open double-row rotator cuff repair using the LASA-DR screw]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Sports Medicine

Background:

• Rotator cuff tears are common injuries, often requiring surgical intervention.
• Traditional repair methods can have variable outcomes and re-tear rates.
• The need for stable, durable, and cost-effective repair techniques is paramount.

Purpose of the Study:

• To evaluate the safety and cost-effectiveness of a novel double-row rotator cuff repair technique.
• To assess the biomechanical stability and clinical outcomes of the lateral augmentation screw anchor (LASA-DR) method.
• To determine the rerupture rate associated with this surgical approach.

Main Methods:

• A prospective analysis of 35 consecutive patients with Bateman-III rotator cuff lesions was conducted.
• The surgical technique involved extensive four-point fixation using the double-row lateral augmentation screw anchor (LASA-DR).
• Postoperative management included a 4-week abduction pillow, followed by physiotherapy and a 4-6 month period for full weight-bearing.

Main Results:

• The study demonstrated excellent clinical results in all 35 patients.
• A low rerupture rate of 6% was observed, indicating high repair integrity.
• The LASA-DR technique provided high biomechanical stability for rotator cuff reattachment.

Conclusions:

• The double-row lateral augmentation screw anchor (LASA-DR) technique offers a safe and cost-effective solution for rotator cuff repair.
• This method achieves excellent outcomes and a low rerupture rate, making it a viable option for treating rotator cuff lesions.
• The high biomechanical stability of the LASA-DR system contributes to successful tendon healing and functional recovery.
