Dr. James Cahill is a board certified orthopedic surgeon, whose private practice is proudly affiliated with Hackensack University Medical Center in Hackensack, New Jersey. He is a senior attending physician and one of the founding members of the Center for Joint Replacement at Hackensack Medical Center.

Dr. Cahill is a fellowship trained sports medicine and reconstruction specialist, in practice for over twenty years and routinely performs arthroscopic and joint replacement surgery of the shoulders, elbow, hip and knee. As a result, cutting edge techniques and technology are always utilized.

Currently, Dr. Cahill has particular interests in joint replacements, arthroscopic shoulder and knee ligament repair/reconstructive surgery as well as treatment of cartilage injuries. Dr. Cahill has lectured on and participated in original research for the treatment of cartilage injuries that ultimately require cartilage repair and reconstruction. He has been selected as a Castle Connolly Top Doctor as well as Inside Jersey Top Doctors. Dr. Cahill states that science and technology are at long last providing a solution for these previously difficult to treat problems.

"My initial approach to most injuries is a non-operative attempt to avoid surgery when possible. When surgical treatment is necessary, current reconstructive techniques can return patients to a full level of activity. Over the past five years, surgical techniques have advanced considerably. We are able to achieve excellent levels of success in patient satisfaction. We are also much better in controlling the discomfort often associated with surgical treatment specifically, joint replacement surgery."
