Partial Knee Replacements On this Mayo Clinic Radio program, Dr. Robert Kyle will discuss how he has stayed grounded in his nearly six decade career. Also on the program, Dr. Mark Pagnano, a Mayo Clinic orthopedic surgeon, will explain why a partial knee replacement is sometimes an option for patients instead of a total knee replacement. And Jay Masters, a grateful radiation oncology patient, will share how his cancer treatment led him to change careers. He became a Mayo Clinic staff member, hoping to make a difference for patients just like him.
