By the way, doctor: Does platelet-rich plasma therapy work for tennis elbow?
Q. You wrote about platelet-rich plasma therapy for chronic tendon problems. Has there been any news since then? I ask because I'm thinking about it for my tennis elbow.
A. Platelet-rich plasma therapy (PRPT) is a technique in which platelets and plasma are drawn from a person's own blood and injected into injured tissue to stimulate the body's repair mechanisms. It's been used to treat chronic tendon problems as well as acute injuries in athletes. Reports of success in treating professional athletes have spurred interest in the technique for treating tendon problems in others as well.
