Farnesol, a sesquiterpene compound, can exert antioxidative and anti-inflammatory effects Citation: Lin, Y.-H.; Lee, S.-I.; Lin, and promote collagen synthesis. In this rabbit model, either commercial SurgiWrap membrane or F.-H.; Wu, G.-X.; Wu, C.-S.; Kuo, S.-M. hydrogel membranes containing various compositions of gellan gum, hyaluronic acid, and farnesol Enhancement of Rotator Cuff Healing (hereafter GHF membranes) were applied to the tear site, and the repair of the cuff was examined with Farnesol-Impregnated Gellan 2 and 3 weeks afterward. The designed membranes swelled rapidly and adsorbed onto the tear Gum/Hyaluronic Acid Hydrogel site more readily and closely than the SurgiWrap membrane.
