Yankees third baseman Alex Rodriguez turned to a new therapy to treat his knee and shoulder. Rodriguez traveled to Germany to receive Orthokine therapy on his right knee and left shoulder, Yankees general manager Brian Cashman said. NBA star Kobe Bryant recommended the procedure after having it performed on his balky knee and ankle. The procedure uses the patient's own blood, which is drawn from the arm and put into a centrifuge to separate out a certain protein. The mix with the protein is then injected into the affected joint. Rodriguez's treatment was first reported by the New York Post.
