Dr. Ika Kirschenbaum: Resurface not Replace

Dr. Ira Kirschenbaum, the Chairman of Orthopedics at Bronxcare Health System, specializes in minimally invasive hip and knee replacement. Dr. Ira Kirschenbaum is also a member of three orthopedic focused organizations. He also has won awards, developed instruments, and hold trademarks of his inventions in the medical field.


In 2012, Dr. Ira Kirschenbaum performed a partial knee replacement on a patient that had been a consistent athlete for 25 years and developed arthritis in one part of his knee. The procedure that Dr. Kirschenbaum performed is referred to as a resurfacing. Since there are three parts of the knee and only one was affected by arthritis, he was able to go in and resurface the affected part of the knee, without damage to the other two parts. He accomplished this by using a replacement that is metal on one side and medical grade plastic on the other.


The resurfacing differs from a total knee replacement in the way that after the surgery the patient is still able to feel their knew. In a total knee replacement the entire knee is taken out and replace, joints and nerves included, so they are not able to feel their knee.


By Dr. Kirschenbaum doing a resurfacing and not a replacement, the patient was able to keep the feeling in his knee and not have to worry about future surgeries, that often come with a total knee replacement down the road. The option for the resurfacing procedure is only available to patients that have minor to mild arthritis that is restricted to one part of the joint. This type of arthritis represents 70% of the causes of knee surgery, so this technique will be very beneficial in helping patients keep more of the feeling in their knee after surgery in addition to recovering quickly
