Abstract
An implantable composition is provided. The composition comprises porous ceramic granules. The porous ceramic granules comprise hydroxyapatite in an amount of about 8 to about 22 wt. % and beta-tricalcium phosphate in an amount of about 78 to about 92 wt. % based on a total weight of a ceramic granule. The composition includes a collagen carrier, and the porous ceramic granules have an average diameter from about 50 μm to 800 μm. Methods of making are also disclosed.
