Robots help recovery time for a new procedure performed in North Carolina.

For David Nichols, Sr., a partial knee replacement using a robotic arm helped him feel like a new person. Before the procedure at Lake Norman Regional Medical Center, Nichols experienced extreme pain and walked with a limp and a cane. He said he couldn't walk 30 feet at any one time.

"This procedure, when it's all done, you don't feel any affects of any artificial pieces," said Nichols. "I mean I can walk, I don't limp and it's really gratifying. [I'm] glad I did it."

Dr. David Hillsgrove, an orthopedic surgeon, said some patients choose not to have a kneed replacement because of the long recovery time.

"So many patients just suffered until which time they could not handle it any longer or the disease process took over other parts of their knee and they required a total knee replacement," he said.

With the robotic arm technology, doctors say patients are usually walking without help within two weeks and are back to work within a month's time.

Another condition that has the potential to clear up quickly happens more frequently during the colder months. Doctors say during the winter months they see more cases of pink eye because we spend more time inside.

Pink eye is an inflammation or infection of the eye that can make it look pink and crusty. It can have many different causes: allergies, simple irritation from a speck of dust to a virus.

Most cases go away on their own. Other times, a cold compress is enough to clear it up.

Pink eye is often contagious and you can prevent it by washing your hands, keeping your child out of school or day care and trying to avoid sharing things like wash clothes.

A new study may provide more options for pregnant women diagnosed with cancer. Researchers say they may not be putting their babies at extra risk of health problems if they choose to have chemotherapy.

In the study in the Lancet Oncology Journal, researchers looked at medical records from 70 children whose mothers had chemotherapy while pregnant. Researchers found no evidence the children had an increased risk of heart, hearing or general health problems. However, they did find the children tended to be born prematurely.
