Hip and Knee Avascular Necrosis (AVN)
Avascular necrosis, often referred to as osteonecrosis, is a disorder in which the blood supply to the bone is disrupted – leading to the area of bone that is without blood supply becomes necrotic or die. Avascular necrosis (AVN) may result from various causes. Trauma is a leading cause. Various other systemic causes for AVN exist. These include high doses of corticosteroids (cortisone), autoimmune disorders (Rheumatoid Arthritis and Lupus), as well following chemotherapy or radiation therapy.
The hip is the most common joint afflicted. It can occur in both hips (bilateral) or may also be seen in the same leg afflicting the hip and knee. The area of bone necrosis may collapse leading to rapid joint secondary degenerative arthritis. Joint replacement is often considered a mainstay treatment, however with the emergence of Regenerative Medicine, alternative therapies such as Stem Cell Therapy and Platelet Rich Plasma (PRP) are increasingly being sought as treatment strategies. Stem cells have been used in a variety of clinical trials for knee osteoarthritis. Therefore, the incorporation of stem cells and PRP into the treatment of AVN and the secondary degeneration that accompanies AVN is viewed as a viable alternative to more invasive joint surgery.
