1. A method of preparing a bone void filler composition, the method comprising:
- combining particles of a porous, osteoconductive material with a solution of a polypeptide to form a slurry; and
adding to the slurry a second polymer under conditions such that the polypeptide crosslinks with the second polymer to form a continuous matrix having the particles of the osteoconductive material dispersed therein;
wherein before said adding step, at least a portion of the pores in the particles of the osteoconductive material have a biocompatible material adsorbed therein.

Abstract
The present disclosure provides compositions useful in regeneration of connective tissue, particularly bone. The compositions comprise a continuous matrix formed of a polypeptide crosslinked with a second polymer and further comprise particles of a porous, osteoconductive material dispersed in the continuous matrix. The composition can be provided in a dehydrated form. The disclosure further provides methods of preparing the composition in a clinically useful form, methods of using the composition in regenerating bone, and kits including the composition.
