J. Andrew Parr, M.D.

Clinical Interests: 
Minimally invasive total hip and knee surgery, alternative bearing surfaces and complex revision hip and knee replacement.

Research Interests: 
Outcomes studies regarding THA, a comprehensive atlas of hip and knee prostheses and an algorithm to assist in identifying implants from x-ray images, as well as a basic science interest in the bone-implant interface and the remodeling rates of bone surrounding well fixed stems, and osteolysis around total joints.
