Dancing With the Stars isn't as fun as it seems when you're Christie Brinkley. The contestant was injured four months ago and has yet to heal properly. Her daughter, Sailor Brinkley-Cook stepped in to take her place on the reality dance competition stage.
In an interview with PEOPLE NOW, Brinkley talks about going in for an appointment to receive platelet-rich plasma, or PRP, which should help her heal faster. PRP is the process of injecting patients' own platelets into the injured area, and is believed to speed the healing process. She's done this before, and is not hesitant to do so again.
