“…6 It is therefore considered that if an intrinsic response could be stimulated at the early stage of tendon healing, the outcome of tendon repair would be preferable with regard to reducing peritendinous adhesion. Based on this idea, a wide range of substances, including fibrin sealant, 11 5-fluorouracil, 12 sodium hyaluronate, 15 aprotinin, 16 and TGF-1 neutralizing antibody, 17 have been experimentally applied to the tendon repair, with the aim of reducing extrinsic healing and stimulating the intrinsic mechanism. However, problems such as high cost of raw materials, potential side effects, and limited bioavailability have prevented widespread clinical use of these agents.…”
