The Blake Griffin Treatment

Los Angeles Clippers’ rookie forward Blake Griffin suffered a non-displaced stress fracture of his left patella during the Clippers’ last preseason game vs. the New Orleans Hornets on Friday, October 23rd.
Griffin, who underwent an MRI yesterday which confirmed the diagnosis, was examined by both team physician Dr. Steven Shimoyama as well as specialist
Dr. Neal ElAttrache. Based on communication between the two physicians, it has been determined that Griffin will be sidelined for approximately six weeks.
During this time Griffin will receive bone stimulation and PRP (Platelet Rich Plasma) treatment.
Griffin originally suffered a bruised left patella during practice on Thursday, September 24th and was eventually cleared to resume full basketball activity.

Alan Schwarz, who’s done some excellent work for Slate, among other outlets, wrote this piece on PRP for the New York Times in February.  Recent recipients of PRP treatment include Hines Ward, Troy Polamalu and Takashi Saito (ElAttrache, who’s on the Griffin team, administered PRP to Saito).
Here’s Schwarz’s basic description of PRP:

The method, which is strikingly straightforward and easy to perform, centers on injecting portions of a patient’s blood directly into the injured area, which catalyzes the body’s instincts to repair muscle, bone and other tissue. Most enticing, many doctors said, is that the technique appears to help regenerate ligament and tendon fibers, which could shorten rehabilitation time and possibly obviate surgery.
