1. A tissue repair implant, comprising:
- a tissue carrier matrix in the form of an injectable suspension, the tissue carrier matrix comprising a plurality of biocompatible, bioresorbable granules and at least one tissue fragment in association with the tissue carrier matrix, the at least one tissue fragment having an effective amount of viable cells that can migrate out of the tissue fragment and populate the tissue carrier matrix;
wherein the at least one tissue fragment has a particle size in the range of about 0.1 to about 2 mm3;
wherein each of the plurality of granules have an average outer diameter in a range of about 150 to about 300 μ
m; and
wherein the at least one tissue fragment is cohesive with the granules within said tissue carrier matrix.
