Patent on Mosaicplasty Implants issued to CPG researchers
US Patent 9,289,302 was issued on March 22, 2016 to CPG researchers. The patent describes designs and methods for making implants for focal cartilage tears in load bearing implants, such as hips and knees. The construct designs make use of a surgical procedure termed mosaicplasty, whereby a plug of healthy osteochondral plug is removed from a non-load bearing portion of the joint, and placed in a drilled out cavity in the focal defect. In this patent, synthetic plugs are created based on hybrid structures of polymers and metal repair the focal defects.
