ST. LOUIS (KSDK) - Lady Gaga fans in St. Louis have to count themselves lucky. Our city stands as one of her last appearances in her "Born This Way Ball" tour.

The pop star's now cancelled the rest of her tour dates due to a hip injury, and apparently, she'll need surgery to relieve something called synovitis.

But what is it, and how common is it?

Dr. Scott Kaar, an orthopedic surgeon from St. Louis University Medical Center, joined First @ 4 to shed some light on it.
