Team Doctors

Dr. William Balcom M.D.

Dr. Balcom is an Orthopedic Surgeon at St. Vincent Hospital that specializes in hip, knee, and shoulder replacements. He is a big believer in using the most modern surgical techniques, and is now performing minimally invasive hip and knee replacements on some of his patients.

A true leader in the field of orthopedic surgery, Dr. Balcom has lectured to audiences across the world on minimally invasive knee and hip replacements and has even invented a new type of artificial knee, which is already being tested. Called the Rotating Bearing Knee, it utilizes a new design concept that improves mobility and reduces wear.
