“…Modification of the adhesion process by various biochemical agents has been attempted, both by placing a mechanical barrier between the healing tendon and the surrounding tissue and by chemically modulating the actual formation of adhesions. The physical barriers to adhesions have included polyethylene membranes, alumina sheaths, polytetrafluoroethylene and chondroitin sulphate-coated polyhydroxyethyl methacrylate membranes and, most recently, ADCON®, a proteoglycan (Austin and Walker, 1979; Eskeland et al, 1977; Golash et al, 2002; Gudemez et al, 2002; Hanff and Hagberg, 1998; Siddiqi et al, 1995). Biochemical modulation of the adhesion process has also been studied extensively in both extrasynovial and intrasynovial tendons.…”
