To treat articular cartilage injuries, your surgeon may remove the damaged tissue using an arthroscopic shaver blade, or may use a specially designed radiofrequency (RF) device to smooth the diseased cartilage and help restore the gliding motion of your hip. Certain types of injuries may require treatment with microfracture. In this procedure, your surgeon will create a number of small holes in the exposed bone of the joint to induce bleeding and clotting, which also leads to new tissue growth. Studies indicate that in time, this new growth becomes firm tissue that is smooth and durable.
