"The total joint replacement of tomorrow begins with the total joint replacement research of today."
Dr. Kurtz currently is enrolling patients in a knee replacement study that correlates the thickness of bone removed during knee replacement surgery with the change in alignment of the leg after surgery and the range of motion after surgery. When a surgeon removes more bone from one side of the knee joint than the other, that surgeon is changing the alignment of the leg. Typically, this is done to straighten a leg that was crooked before the knee replacement. In addition, if a surgeon takes away less thickness of bone than the thickness of the metal and plastic knee replacement components, then that patient has had their ligaments stretched, might be stiff, and might have a hard time getting their knee flexion and extension back. Conversely, if a surgeon takes away more thickness of bone than the thickness of the metal and plastic knee replacement components, then that patient might have loose ligaments and complain that their knee is unsteady, unstable, and undependable.
Dr. Kurtz recently completed his research comparing customized knee replacements to "off the shelf" knee replacements using Dr. Komistek's fluoroscopic kinematic lab in Knoxville. These results have been reported at the ICJR Pan pacific meeting and the Tennessee Orthopedic Society Meeting. In short, the customized knees moved more like a normal knee joint.
Dr. Kurtz is enrolling patients in a prospective outcomes based study that looks at the Conformis Itotal CR knee replacement system.
Dr. Kurtz's past research include computer modeling of hip replacements to look at the affects of translating the center of rotation on the range of motion of the hip and biomechanics of the hip joint. Over 30,000 computer generated leg motions were tested. This study was published in the Journal of Arthroplasty in June of 2010.
Dr. Kurtz also recently published his research on his patented leg length device in Journal of Arthroplasty in January of 2012. In this study, 100 patients recieved a total hip replacement with the SuperPath technique and Dr. Kurtz's in situ leg length guide.
