Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Use of an allopatch augmentation graft by an consultant orthopaedic surgeon in surgical rotator cuff repair. The graft is an acellular dermal allopatch graft that has been treated and suitable for surgery. It theoretically provides a mechanical bridge to aid in the strength of the repair. This will occur as an additional step during an arthroscopic repair of the rotator cuff at a certified hospital to repair the rotator cuff that adds roughly an extra 20 minutes and overall takes 1.5-2h to complete the surgery.

Summary
Brief summary
To compare whether use of a dermal allopatch graft in rotator cuff repair leads to improved functional and structural outcomes over a 2-year period compared to no graft. It is expected the use of these grafts will improve functional shoulder outcomes and reduce the re-tear rate following surgery. If successful these grafts can be potentially considered a gold standard of care moving forward. We will also be monitoring for any changes in adverse event profile.
