Tendon trap technique for rotator cuff repair.
Strangulation around cuff tissue is a possible cause of retear after rotator cuff repair. Therefore, tendon healing ideally requires changes in suture tension over the cuff tissue in accord with rotator cuff muscle activity. The authors present a type of fixation that mimics the mechanism of the Chinese finger trap. The devised knot-free tendon trap technique resembles the double-pulley-suture ...

متن کاملQuantitative phase measurements of tendon collagen fibres.
Collagen is the main component of structural mammalian tissues. In tendons, collagen is arranged into fibrils with diameters ranging from 30 nm to 500 nm. These fibrils are further assembled into fibres several micrometers in diameter. Upon excessive thermal or mechanical stress, damage may occur in tendons at all levels of the structural hierarchy. At the fibril level, reported damage includes...
متن کاملAllogenous tendon stem/progenitor cells in silk scaffold for functional shoulder repair.
Tendon stem/progenitor cells (TSPCs) were recently identified within tendon tissues. The aim of this study was to investigate TSPC-seeded knitted silk-collagen sponge scaffold for functional shoulder repair. The multidifferentiation potential, proliferation, and immune properties of TSPCs were investigated in vitro, while the efficacy of TSPC-seeded knitted silk-collagen sponge scaffolds in pr...
متن کاملAlignment of collagen fiber in knitted silk scaffold for functional massive rotator cuff repair.
Rotator cuff tear is one of the most common types of shoulder injuries, often resulting in pain and physical debilitation. Allogeneic tendon-derived decellularized matrices do not have appropriate pore size and porosity to facilitate cell infiltration, while commercially-available synthetic scaffolds are often inadequate at inducing tenogenic differentiation. The aim of this study is to develop...
