This procedure stimulates the underlying bone marrow of the affected area so that stem cells migrate to the area and can promote cartilage regrowth. The migration of bone marrow and stem cells promotes the growth of fibrocartilage to the affected area. Fibrocartilage then fills the defect and helps improve the overall biomechanics and stresses in the knee. This has been shown to have good results in short-term follow-up studies.
