Narrator: This is Science Today. Radiofrequency has been around hundreds of years in medicine, but with the advent of the laser, it's use diminished. Now, because it's cost-effective, many different fields are finding new uses for it. Dr. Stephen Liu of UCLA, says they're using a radiofrequency technique called ElectroThermal Arthroscopy to treat shoulder instability.
Liu: Shoulder instability is defined as excessive movement of the shoulder that cause pain in daily activities or sporting activities. So, people that have dislocated their shoulder or they're just born naturally loose or they have acquired condition of loose. It affects them in their overhead activities.
Narrator: These conditions are traditionally treated with open surgery, but in using a radiofrequency heat probe, patients recover quicker - with more motion and less pain.
Liu: This is a new, innovative tool to treat shoulder instability and a cost-effective basis and you see the stabilization - means you're fixing the shoulder at the time of the surgery. So you could actually see the tissues shrink.
