About

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.

The MegaCarti® is applied after Microfracture treatment on patients with Knee Cartilage Defects. The cartilage regeneration, which is a primary endpoint, is compared to the Microfracture group through MOCART evaluation. In addition, the improvement of pain and the recovery of Normal Range of motion are compared to the Microfracture group through secondary endpoints. Then, long-term follow-up study for 5 years is conducted to the experimental group.

Long-term follow-up Study is performed to subject that completes 48-week visit, at every 6 months for 5 years.

Treatment:

Procedure: Microfracture

Device: MegaCarti®

Microfracture only

Active Comparator group

Description:

The control group undergoes microfracture and they visit at 6 weeks, 12 weeks, 24 weeks, and 48 weeks after surgery to conduct examinations and assess Questionnaires.

Treatment:

Procedure: Microfracture
