Detailed Description
The MegaCarti^® is the decellularized allogeneic cartilage and acts as a cover after bone marrow stimulation to prevent the loss of blood clots and induces cartilage regeneration by assisting in the location of stem cells derived from bone marrow.

To evaluate cartilage regeneration, the study group is compared with the microfracture group alone through MOCART evaluation at 48 weeks after treatment for cartilage regeneration. In addition, a biopsy is performed to evaluate the formation of hyaline cartilage and the area ratio of regenerated cartilage is measured.
