Elbow replacement surgery gives Saxonburg woman her life back. Kathleen (Kathy) Shields is not the type of person to be easily deterred by a setback. A 71-year-old retiree from Saxonburg, Kathy is energetic, cheerful and positive. Her 1,000-watt smile could light a darkened room and her contagious optimism could lift even the bleakest of spirits. But Kathy's upbeat outlook to life was put to the test after she suffered a devastating injury in 2005. "I didn't think I would be the same again," said Kathy, "until I saw the orthopaedic specialists at Allegheny General Hospital."
