Understanding Partial Knee Replacement – Dr. Ira Kirschenbaum

A patient of orthopedic surgeon Dr. Ira Kirschenbaum named Robert was very active throughout his life playing football, softball, basketball and he even did karate; however, his love for sports took a toll on his body over the years. Robert developed arthritis in one of his knees and would need surgery. As Robert stated, “the knee pain was tremendous with throbbing.” He used over the counter pain medication frequently.


Dr. Ira Kirschenbaum elected to perform a partial knee resurfacing on Robert as Dr. Ira Kirschenbaum stated a knee has three separate compartments and in doing a partial knee resurfacing it only repairs the part of that knee which is damaged and needs replacing instead of the whole knee.


Dr. Ira Kirschenbaum is able to resurface the end of the diseased area of the bone with metal on one side of the knee and plastic on the other side of the knee leaving all of the ligaments intact with the feeling to the patient as if it is their natural knee.


As Dr. Ira Kirschenbaum mentioned when a total knee replacement is done, “the whole knee gets chopped out,” and years down the road you may have to put in another total knee. Dr. Ira Kirschenbaum did say that partial knee resurfacing is not for anyone that has severe arthritis or rheumatoid arthritis. Patients who have osteoarthritis restricted to any one particular part of the knee joint would be an excellent candidate.


Dr. Ira Kirschenbaum is currently at the BronxCare Health System in Bronx, NY where he has been for over ten years. He is the Chairman of Orthopaedics and has been the winner of various awards for innovation, success, and service as well as a recent patent.
