Dr. Ira Kirschenbaum, chairman of Orthopedics at Bronx-Lebanon specializing in minimally invasive hip and knee replacement among other fields of study, discussed the subject of partial knee replacement in the video: ‘Dr. Ira Kirschenbaum on WPIX – 11 the alternatives to knee replacement’ available on YouTube.
With a unique and notable career as an orthopedic surgeon with in-depth and widespread experience in a number of other fields Kirschenbaum explains the knee consists of three separate compartments and if only one part of the knee is diseased they have the opportunity to replace only the diseased part of the knee unlike a total knee replacement; in which the whole knee is surgically removed and replaced with the possibility of a repeat surgery due to failure years down the road.
Instead, the end of the bone is resurfaced with metal on one side and high-density medical plastic on the other, leaving the rest of the knee intact and all ligaments feeling as if they were the original knee. Any trauma to healthy bone and tissue is minimalized because only the surface of the knee is replaced.
Dr. Kirschenbaum is actively involved in his medical research and holds numerous trademarks and inventions in medical information systems and surgical instruments. Developing instruments for unicompartmental knee replacements and designing cement hip replacement systems as well as developing DVD optimizing techniques.
Ira was quoted saying “Anyone with osteoarthritis restricted primarily to one part of the joint is an excellent candidate”. Which represents about 70% of all knee arthritis, however, it is not an effective treatment for people with severe arthritis and those battling rheumatoid arthritis.
