Editorial Commentary: Collagen Bridging of Massive Rotator Cuff Tears Using Fascia Lata Autograft Could Provide a...

Shoulder rotator cuff tears are ideally primarily repaired, but large and massive, chronic, and/or retracted tears result in challenges. In response, innovative solutions include superior capsular reconstruction, tendon transfer, subacromial balloon spacer placement, tuberoplasty, partial repair, and marginal convergence. A recent innovation is to use collagen tissue to bridge repair of compromised tendon. Recent research using fascia lata autograft for supraspinatus tendon reconstruction in a rat model has shown positive outcomes with structural similarity to the normal muscle-tendon interface, decreased fatty infiltration, and increased type I and III collagen, suggesting enhanced mechanical strength. In human subjects, the advantages of autograft outweigh harvest-site morbidity, noting that Dacron, Teflon, and xenograft show poor results. Ideally, a graft might be composed of a degradable scaffold, possess mechanical strength, and amalgamate stem cells, growth factors, and matrix proteins to facilitate host-tissue integration.
