Evaluating Cryopreserved Osteochondral Allograft Cores for the Treatment of Osteochondral Lesions in the Knee

Patients who have a symptomatic full-thickness cartilage lesion (Grade 3 or 4) on the femoral condyle, in a mechanically stable knee, or is being mechanically stabilized in the same procedure, between 2.0-8.0 cm2 in size, and cystic changes requiring osseous repair present in less than or equal to 12 mm of subchondral bone will undergo a osteochondral transplant by removing the damaged cartilage and replacing that cartilage with a cryopreserved osteochondral allograft core.
