The area of injury at the site of knee osteoarthritis is then identified, reinjured using another special technique to induce an inflammatory response. This process causes the thrust bearings suppliers formation of bony spurs, called osteophytes. For instance, patients above the age of 70 75 may not be the best candidates because of sluggish stem cell response..
The field of regenerative medicine has long believed that adult stem cells have the potential to significantly protect and possibly regrow cartilage in conditions such as knee osteoarthritis. Using ultrasound guidance, the stem cells are then introduced into the knee along with platelet rich plasma, a component of whole blood, that stimulates receptors located on the surface of stem cells to cause multiplication and division of the stem cells..
Stem cell transplantation for the study and treatment of osteoarthritis in humans is now being conducted at a few centers.
Lead researcher Professor Charlie Archer reports, We have identified a cell which, when grown in the lab, can produce enough of a person s own cartilage that it could be effectively transplanted..
The results showed that osteoarthritic sheep knee joints receiving stem cells had significantly greater thickness of joint cartilage, reduced cartilage breakdown, and greater biomechanical strength three months later than did control joints. The authors suggested that both the aging process and osteoarthritis share biological factors in common, including oxidative stress and low level chronic inflammation.
Many studies have been conducted both in large animals as well as humans.
Osteoarthritis is a disease caused by wear and tear. run a 10 K race., a world renowned arthritis researcher.
