Interposition grafting for irreparable rotator cuff tears: Systematic review and specialist practice report.

The treatment of symptomatic irreparable rotator cuff tears poses significant challenges to both patients and shoulder surgeons. Although reverse shoulder arthroplasty provides reliably good outcomes in the elderly, it is not a good option in younger patients. Various surgical techniques have been proposed for the treatment of irreparable rotator cuff tears; however, no gold standard currently exists. Interposition grafting is used when the rotator cuff cannot be fully repaired onto its footprint, and the remaining defect is bridged with either an allograft, autograft, xenograft or a synthetic graft. This review aims to present the literature on the use of various interposition grafts and techniques to treat large or massive irreparable rotator cuff tears and provide a specialist practice report.
