Abstract
An implantable composition can include methacrylated solubilized devitalized cartilage (MeSDVC) with or without devitalized cartilage (DVC) particles. These compositions can be hydrogel precursors. After implantation, the MeSDVC may be crosslinked so as to form a hydrogel. The crosslinked hydrogel can include the DVC particles. A hydrogel precursor matrix (e.g., not crosslinked) can include a crosslinkable substance that can be crosslinked into a hydrogel, where DVC particles are included in the precursor matrix. The hydrogel precursor matrix can be located in a tissue defect site, such as a hole or recess in a cartilage or bone, and then crosslinked into a hydrogel that has the DVC particles therein.
