Police say 54-year-old Timothy Lenhart attacked his girlfriend, Jennifer Hix, last month.
During a court hearing Monday, Jeannette Police Officer Justin Scalzo said Hix suffered broken ribs and facial injuries in the July 10 attack. Hix had to be airlifted to a hospital.
In March 2009, Lenhart was acquitted of all charges after police said he intentionally poked Hix's eye out during an argument. Lenhart claimed he was acting in self-defense after Hix picked up a glass table.
Lenhart denied the charges following Monday's hearing. He faces charges including attempted homicide and aggravated assault.
