There are many methods of operative repair of articular cartilage. The choice of method depends mainly on the characteristics of the cartilage damage - whether it is traumatic or degenerative, as well as the size and depth of the defect. The age and level of activity of the patient are also important. The most frequently used methods include: the microfracture method, autologous chondrocyte transplantation, and cartilage-bone block grafts. The decision on the choice of technique is made by an orthopedic surgeon specializing in cartilage repair procedures.
