Platelet Rich Plasma
PRP is plasma with many more platelets than what is typically found in blood. The concentration of platelets — and, thereby, the concentration of growth factors — can be 5 to 10 times greater (or richer) than usual.
What Conditions are Treated with PRP?
Chronic Tendon Injuries
According to the research studies currently reported, PRP is most effective in the treatment of chronic tendon injuries, especially tennis elbow, a very common injury of the tendons on the outside of the elbow. The use of PRP for other chronic tendon injuries — such as chronic Achilles tendonitis or inflammation of the patellar tendon at the knee (jumper's knee) is promising. However, it is difficult to say at this time that PRP therapy is any more effective than traditional treatment of these problems.
Some initial research is being done to evaluate the effectiveness of PRP in the treatment of the arthritic knee. It is still too soon to determine if this form of treatment will be any more effective than current treatment methods.
