Anderson Orthopaedic Research Institute

This website provides information and current research findings on total hip and knee replacement surgeries for both the public and medical professionals.
Progress worthy of celebration...

Since 1972, the Anderson Orthopaedic Research Institute (AORI) has researched the outcomes of total hip replacements and total knee replacements. Our goal is the continual improvement of these procedures. Today, we celebrate the enormous strides made in total joint arthroplasty over the past 3 decades. Because of these advances, millions of patients with arthritis and other crippling diseases have been able to lead painfree, active lives.

Looking for Answers

AORI stands apart from other total joint research institution for 2 reasons. Reason 1 is the guidance given to our research efforts by the physicians of the Anderson Clinic in Alexandria, Virginia.
Reason 2 is AORI's unsurpassed collections of patient information, which enable long-term follow-up of total hip and knee arthroplasties. AORI 's patient database, radiographic archives, and implant retrieval bank are among the most extensive joint replacements collections in the world.
We thank the patients of the Anderson Orthopaedic Clinic who have supported our research by allowing us to study their outcomes and by bequeathing their implants to our
retrieval collection.

  We welcome your thoughts concerning the information on these pages. We do not, however, provide on-line medical advice.
