| Research Abstract |
Little is known about biologic methods to improve tendon-to-bone repair or regeneration.Because growth factors are expressed during various phases of bone and tendon repair,there has been considerable interest in their recombinant proteins as therapeutic agentsto enhance such repairs. We hypothesized that FGF-2 may improve the strength and qualityof the regenerated tendon in rats undergoing rotator cuff reconstruction with an acellulardermal matrix (ADM) graft. The purpose of this study was to determine whether the localapplication of FGF-2 accelerates regeneration and remodeling of rotator cuff tendondefects grafted with ADM. In conclusion, the histological remodeling of ADM grafts placedin rat rotator cuff defects was accelerated by the local administration of FGF-2 due toincreasing number of proliferating cells and gene expression of col1, col3 and Biglycanin the graft and ADM grafts can be preconditioned with the application of FGF-2 to improvetheir biomechanical properties
