A novel transosseous button technique for rotator cuff repair

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Sports Medicine

Background:

• Rotator cuff tears often require surgical repair to restore shoulder function.
• Maximizing stability and footprint compression is crucial for successful rotator cuff repair outcomes.
• Current techniques may involve multiple anchors, increasing complexity and cost.

Purpose of the Study:

• To present an innovative surgical technique for rotator cuff repair.
• To enhance lateral footprint compression and improve repair stability.
• To achieve a double-row repair equivalent using a single fixation device.

Main Methods:

• Utilizing a rotator cuff button passed through a transosseous tunnel.
• Loading the button with four suture strands for a dual-purpose repair.
• Employing central strands for primary repair and peripheral strands for compression sutures.

Main Results:

• The technique achieves robust primary fixation and significant lateral tendon compression.
• A double-row repair configuration is effectively replicated.
• The method demonstrates cost-effectiveness by using a single fixation device.

Conclusions:

• This innovative technique offers improved stability and compression in rotator cuff repair.
• It provides a cost-effective alternative to traditional multi-anchor methods.
• Clinical application has not revealed theoretical risks to the axillary nerve or issues with osteoporosis.
