Dr. Charles A. Engh, Sr.
  Total Hip Arthroplasty

Dr. Gerard A. Engh (Jerry)
Knee Replacements

Dr. C. Anderson Engh, Jr. (Andy)
Knee Replacements, Total Hip Arthroplasty

 

 


Drs. Charles Engh, Sr., Gerard Engh, C. Anderson Engh, Jr., William G. Hamilton, and Kevin B. Fricka of the Anderson Orthopaedic Clinic of Alexandria and Arlington, Virginia, spearhead the Anderson Orthopaedic Research Institute (AORI). With their expertise in total hip replacements and knee arthroplasty, these physicians guide research projects that address today's important issues in this field. Both their own patients and patients around the world benefit from their research endeavors.

You will find brief profiles on these physicians below.

 

Dr. Charles Engh
Medical Director, AORI and the Joint Replacement Unit, Inova Mount Vernon Hospital

"No matter what activities we are involved in,our primary concern is the well-being of our individual patients."

Charles A. Engh Sr., MD

 

 

 

Over his 30 years in orthopaedic practice, Dr. Charles Enghs concern for his patients has mingled with his passion for orthopaedic research. In the early 1980s Dr. Charles pioneered the development of the porous-coated cementless implant for hips, an innovation that changed the nature of joint replacement surgery.

Dr. Charles has published research findings in over 100 articles in scientific journals, contributed chapters in 13 books on joint replacement, and written a book on joint replacement. He never tires of tackling hurdles and pursuing progress through research in total hip arthroplasty. Dr. Charles presents his findings in presentations throughout the world (see hip research for papers and presentations). One of his current research concerns is increasing the longevity of hip implants by resolving the problems of implant wear and osteolysis (bone loss) around implants.

Gerard (Jerry) A. Engh, MD
Director of Knee Research,
AORI
President, AORI Board of Trustees



"We follow the progress of patients closely and have built an extremely useful database on their long-term outcomes. This helps us provide better care for all of our patients, and to address the issues that affect all knee patients."

Gerard A. Engh, MD

 

 

Dr. Gerard A. Engh, son of founder O. Anderson Engh, has pioneered research and development of knee implants for the last 30 years. Recently, his collaborative efforts resulted in a new minimally invasive unicompartmental knee procedure. He has published over 50 articles for scientific journals, co-edited a book on revision knee replacements, and written numerous chapters related to joint replacement.

Dr. Jerry frequently conducts presentations and grand rounds in the United States and internationally. He is Vice President of the Knee Society, an active member of the American Academy of Orthopaedic Surgeons, and an Associate Professor at the University of Maryland School of Medicine. After graduating from medical school at the University of Virginia, he completed his internship and residency at Yale-New Haven Hospital, and served two years as a major in the Army Medical Corps.

As director of knee research at AORI, Dr. Jerry focuses on issues that can improve patient satisfaction and the long-term performance of knee replacements (see knee research for papers and presentations). For example, Dr. Gerard's research on a commonly used revision procedure for patients whose knee implants wore out early has shown clinicians that standard revisions have better results.

C. Anderson Engh, Jr. (Andy)
AORI Board of Trustees


"Hip replacement is major surgery that can dramatically improve the quality of life. Im proud to continue the tradition of innovative and caring treatment my grandfather started."

C. Anderson Engh Jr., MD

 

 

Dr. "Andy" joined the Anderson Orthopaedic Institute 13 years ago, becoming the third generation of Engh's to perform total joint replacement surgery and research. Dr. Andy enjoys challenging cases; he frequently performs difficult revision surgeries and shares his surgical techniques with other physicians through speaking engagements, live surgeries, and articles.

Dr. Andy's ongoing research includes long-term outcomes of hip arthroplasties, clinical procedures for knee wear, and investigations concerning osteolysis. He has published articles in scientific journals, co-authored a book on hip revision surgery with Dr. Charles, and spoken at orthopaedic conferences in the U.S. and abroad.

An example of one of Dr. Andy's highly useful research studies is the Wear-Through of A Modular Polyethylene Liner: Four Case Reports, This study gives clinicians insights on signs of late wear-through with SROM stems.
