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

Patients between the ages of ≥12 years and ≤ 60 years 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 0.9-8.0 cm2 in size, and cystic changes requiring osseous repair, as confirmed by MRI , CT scan, or arthroscopy, and undergoing an osteochondral transplant procedure will be eligible for enrollment. Patients will receive one or more cryopreserved osteochondral allograft core transplants to replace damaged cartilage.

Patients will be followed for up to 60 months post-procedure (6 weeks, 3 months, 6 months, 12 months, 24 months, 36 months, 48 months, and 60 months) to evaluate short and long-term outcomes of the procedure using the cryopreserved osteochondral allograft cores.
