GPS for Knee Surgery

Ever since Sandra Liddy injured her knees during a training exercise 17 years ago, she has been dealing with constant throbbing and stabling pain that made it difficult for her to do her job. The pain persisted even after she had surgery to repair her knee. Recently, when doctors told her she needed total knee replacement surgery, Sandra turned to surgeon Dr. Jaime Hernandez, who used GPS technology to perform the procedure. Dr. Hernandez explains that in the past, surgeons have used protractors and rulers to place the knee components, but the new GPS technology maps out a patient’s anatomy so he can better align the parts.
