NYT runs an interesting story today on a new form of therapy to heal ligaments and tendons: injection of platelet rich plasma into injured joints. I was making platelet rich plasma in high school--the hardest part is getting the subject to sit still while you draw the blood! The charge of $2 000 is a joke--the whole process takes an hour to make the stuff from the patient's own blood. Apparently you just inject the stuff into the joint and watch as ligaments and tendons heal up. There are few clinical trials but high-profile athletes have been using the procedure with good results especially in the recent Super Bowl. http://www.nytimes.com/2009/02/17/sports/17blood.html?pagewanted=1
