Dr. Ira Kirschenbaum is an orthopedic surgeon who specialized in minimal hip and knee replacement, joint reconstruction, complex joint replacement surgery, and arthroscopy. His training in reconstructive surgery took place in Philadelphia at The Rothman Institute, and he currently practices medicine in White Plains.



He came up with instruments which he uses for partial replacement of the knee, and in addition he designed a system for hip replacement without the use of cement. When talking about a specific case, Robert, who has been active for 25 years in a number of sports, developed arthritis and was in need of surgery to replace his knee. He was experiencing a lot of pain, and in order to alleviate it, Dr. Kirschenbaum performed partial knee resurfacing.



The doctor explains that the knee has 3 compartments and that when only a single compartment is diseased, they can replace it without having the need to replace the whole knee. He simply has to resurface the affected part at the end of the bone, thus leaving the rest of the knee with its ligament intact.



Dr. Ira Kirschenbaum notes that for patients with severe arthritis in their knees, partial knee replacement does not become an option. The surgery is designed for those who have pain in one part of the joint, which represents 70% of the patients with knee arthritis. He has been at the forefront of the research which led to partial knee replacements, ceramic hip replacements, and the skills necessary to perform knee replacements.



Dr. Kirschenbaum is a founding executive director at Medscape Orthopedics on the internet, which is part of WebMD. In addition, he is a member of The Orthopaedic Research Society, among other association. In 1994 he was awarded with the James A. Vohs Award, at a time when he was working at Kaiser Permanente as chief of reconstructive surgery.
