Cartilage Replacement – 5 Ways to Replace Worn Cartilage

Cartilage replacement is often performed to correct cartilage damage, especially in the knee joint. Men and women bothered by chronic pain in the knee due to the deterioration of cartilage are the usual candidates. But how is cartilage replacement surgery done? There are several surgical methods that can be used, but this article looks at 5 ways to replace worn cartilage.

Why cartilage replacement may be necessary

Cartilage is the rubbery material that acts as a cushion at the end of the bones, and virtually acts as a ‘shock absorber.’ However, if the cartilage is damaged or starts to deteriorate, this can cause pain and impair mobility.  Left untreated, it can undermine the structure of the knee joint, and necessitate knee replacement.

5 ways to replace worn cartilage

1.    Microfracture Surgery:  During the procedure, small holes are made in the knee bone. This helps to improve the flow of blood to bone on the surface of the knee, thereby stimulating the growth of cartilage.
2.    Sub-chondral drilling:  This is a similar technique to Microfracture surgery, but the holes are made using wires or a surgical drill.
3.    Autologous chondrocyte implantation: This procedure is done in 2 stages. Healthy cartilage is removed from a non-weight bearing knee joint, and the cells are grown in the lab for several weeks. The grown cells are then implanted in the knee.
4.    Osteochondral Autograft Transplantation: Healthy cartilage (graft) is removed from one area of the knee, and then implanted in the damaged portion.
5.    Osteochondral allograft transplantation: This procedure also uses a graft, but the graft is taken from a bone bank, rather than from the patient.
