December 19, 2013 “Materials, Biologics, and Technique Advancements in Joint Replacement: Can A Joint Replacement Last Forever?” Donal P. Endrizzi, MD, and Brian J. McGrory, MD, Maine Medical Center

Drs. Endrizzi and McGrory explore three major advances in total joint surgery that now make shoulder, hip, and knee replacements potentially last two or three decades, even in younger, active patients. New ingrowth enhancing biomaterials have made bony ingrowth necessary to anchor prostheses permanent in most cases, and have eliminated joint loosening. Advances in bearing surface technology, such as highly cross-linked polyethylene, have proven pivotal in prosthesis endurance. Production of wear by-products now seems to be below the threshold that the body can eliminate, minimizing side effects. Development of contemporary techniques has widened the number of maladies that are treatable by joint replacement, and minimized complications that could threaten prosthesis success and longevity.

Dr. Donal Endrizzi specializes in disorders of the shoulder and shoulder surgery to correct those disorders.  Those surgeries include various types of shoulder arthroplasty (replacement) including resurfacing and reverse shoulder replacement, as well as shoulder arthroscopy, rotator cuff repair, repair for recurrent dislocation, ligament reconstruction, and fracture repair.  He is a member of the American Shoulder and Elbow Surgeons organization, an invitation only society for leaders in the field of shoulder and elbow surgery.   He is an editorial board member for the Journal of Shoulder and Elbow Surgery and an associate editor for the American Journal of Orthopaedics.  He has been recognized by US News and World Reports as one of the “top doctors” in the US. 

Dr. Brian McGrory specializes in arthritic disorders of the hip and knee , and surgery to correct those disorders.  Surgeries include various types of arthroplasty (replacement) including anterolateral minimally invasive and posterior hip replacement, revision hip surgery, total knee replacement and partial knee replacement as well as hip fracture surgery and surgery for osteonecrosis of the hip.  He is a committee chairman of the American Association of Hip and Knee Surgeons organization, a society for leaders in the field of hip and knee surgery.   He is an editorial board member for the Journal of Arthroplasty.  He has been recognized by Becker’s Review as one of 70 Outstanding Hip Surgeons and Specialists in the United States.
