The term “iron man” can call to mind either the classic character made popular in comic books and the movies or a super-fit person who rides, swims, and runs for hours on end. Michelle is the latter. Like many of us, she loves to run and ride her bike. A meniscus surgery left her struggling for years with constant knee pain and ended her ability to run. When she was presented with the option to have knee-replacement surgery at a relatively young age—which likely would end her dream of finishing the Ironman race—or to undergo the patented Regenexx stem-cell procedure and avoid surgery, she chose Regenexx. Documentary film-maker Doug Orchard has captured the story of her successful outcome.
