Abstract
A method of synthetic grafting of bone-tendon-bone autograft harvest sites using preformed synthetic trapezoidal implants. The implants are formed of tricalcium phosphate, an osteoconductive bone graft substitute and filler, which allows for simultaneous controlled absorption and promotion of osteogenesis. The implants are preferably pretreated or presoaked intraoperatively in autologous blood, or autologous conditioned plasma, or bone marrow aspirate products to enhance healing ability. The implants are trimmed to match the patellar pole shape, pressed into place in the bone voids, and oversewn to complete the procedure.
