Hip Arthroscopy: A New Solution for Hip Pain

Timothy Greene, MD

Timothy Greene, MD

ONS orthopedic surgeon and sports medicine specialist Dr. Tim Greene will talk about common causes of chronic hip pain including hip impingement,  a painful and often unrecognized condition that involves a tear in the labrum. Now surgeons can repair labral damage and re-contour malformed bone using hip arthroscopy, a minimally invasive technique that uses two small incisions, a small camera and miniaturized instruments.

Dr. Greene graduated Princeton University and earned his medical degree at the Medical College of Georgia. He performed a residency in orthopedics at Emory University and served as associate team physician to the athletic teams at Georgia Tech. He completed fellowship training at the Steadman Hawkins Clinic in Vail, Colorado.
