Abstract:
This invention relates to a process to facilitate osteochondral bone remodeling. The process involves the steps of: administering an effective amount of an injectable in situ curing biomaterial composite to a site. The biomaterial composite product is prepared by a process involving the steps: admixing an alginate solution with a nonporous aggregate of p-tricalcium phosphate, in a sufficient amount to initiate polymerization of the alginate solution, to form a hydrogel having from between 10 to 20 percent by volume of p-tricalcium phosphate.
