Interposition GraftJacket allografts for irreparable rotator cuff tears.

Area of Science:

• Orthopedic Surgery
• Regenerative Medicine
• Biomaterials Science

Background:

• Irreparable rotator cuff tears present a significant challenge in orthopedic surgery.
• Long-term outcomes of human dermal allografts for these tears are not well-established.
• Reverse shoulder arthroplasty is often considered for severe cases, but may not be ideal for younger, active patients.

Purpose of the Study:

• To evaluate the long-term outcomes of using human dermal allografts for symptomatic irreparable rotator cuff tears.
• To determine the efficacy of this treatment in young patients, potentially avoiding the need for reverse shoulder arthroplasty.
• To assess functional recovery, pain reduction, and patient satisfaction over an extended follow-up period.

Main Methods:

• A prospective study involving 45 patients (47 shoulders) with irreparable rotator cuff tears.
• Open reconstruction using an interposition GraftJacket allograft.
• Assessment of Oxford Shoulder Score (OSS), pain, and range of motion (ROM) preoperatively, at one year, and at a mean of 9.1 years postoperatively.

Main Results:

• Significant improvements in OSS were maintained from one year to 9.1 years postoperatively (p < 0.001).
• Significant and sustained reductions in pain scores were observed throughout the follow-up period (p < 0.001).
• Marked improvements in shoulder range of motion and high patient satisfaction were reported.

Conclusions:

• Interposition human dermal allografts yield good, durable outcomes for irreparable rotator cuff tears.
• The benefits of this treatment are maintained at a mean nine-year follow-up.
• This approach represents a successful alternative to reverse shoulder arthroplasty in select patient populations.
