The invention relates to an implantable prosthetic device for the repair of connective tissue in an animal or a human. In one embodiment, an implantable prosthetic device (100) for the repair of connective tissue (500) in an animal or human is disclosed which comprises a biocompatible pad (101) having an open structure to provide a scaffold for the in-growth of tissue into the pad and a reinforcement region (206) attached to or formed integrally with the pad. The device is arranged so that it can be attached to tissue by forming a puncture (301) either a) within the reinforcement region, or b) in an area of the pad which is inboard of the reinforcement region, so that a suture (300) can be located through the puncture, the reinforcement region serving to support tensile loading in the device during use by resisting pull-through of the suture.
