Methods for making an osteoimplant are provided. In one embodiment the method includes applying a mechanical force to an aqueous slurry of insoluble collagen fibers to entangle the insoluble collagen fibers so as to form a semi-solid mass of entangled insoluble collagen fibers; and lyophilizing the semi-solid mass of entangled collagen fibers to form the osteoimplant. An osteoimplant containing entangled insoluble collagen fibers is also provided.
