Full-Thickness Massive Rotator Cuff Repair With a Dermal Allograft Using CuffMend Augmentation Technique

Area of Science:

• Orthopedic Surgery
• Biomaterials Science

Background:

• Rotator cuff tears, especially large-to-massive ones, often require graft augmentation for improved outcomes.
• Traditional graft augmentation can be technically demanding, posing challenges in graft deployment and positioning.
• CuffMend presents a novel, user-friendly technique for rotator cuff augmentation.

Purpose of the Study:

• To introduce and evaluate CuffMend, a new graft augmentation technique for rotator cuff tears.
• To demonstrate the efficacy of CuffMend in simplifying graft implantation and improving clinical results.
• To highlight the benefits of CuffMend for patients with high-risk rotator cuff tears.

Main Methods:

• CuffMend utilizes a decellularized dermal allograft combined with a specialized graft deployment device.
• The technique incorporates a novel tendon anchor and knotless, tension-able anchors for secure graft fixation.
• Sutures are passed in a mattress configuration to secure the rotator cuff, followed by graft placement using a spreader.

Main Results:

• The described patient case shows expected recovery with physical therapy initiated at 1 month postoperatively.
• The patient achieved pain-free light activities of daily living and overhead reach.
• Strengthening exercises are planned to commence at 12 weeks postoperatively.

Conclusions:

• CuffMend provides a reliable and stable method for rotator cuff graft implantation.
• The technique's novel deployment device ensures consistent and precise graft placement.
• CuffMend facilitates expedited rotator cuff repair, potentially leading to optimal clinical and biomechanical outcomes in high-risk patients.
