The University of California San Francisco Medical Center offers injected cartilage repair operations targeted for individuals with deteriorated knee cartilage who do not have osteoarthritis. The procedure is called autologous chondrocyte transplantation, which takes several weeks, states UCSF Medical Center.
Autologous chondrocyte transplantation consists of harvesting healthy cartilage cells, growing them in a laboratory for weeks, then injecting the healthy, grown cells into the defective area, explains UCSF Medical Center.
Cortisone injections into the knee are available for individuals suffering from osteoarthritis, a condition caused by deteriorated cartilage, according to the Palo Alto Medical Foundation. While the anti-inflammatory cortisone suppresses some arthritic symptoms from acting up, research shows cortisone injections can deteriorate healthy cartilage.
