Are Outcome and PE Wear Performance of OxZr Femoral Components Better Than CoCr Femoral Components?
Podium No: 583 Friday, February 27, 2009 03:06 PM – 03:12 PM Location: Venetian Hotel Room 2201 Young-Hoo Kim, MD Seoul None Korea, Republic of Jun Shik Kim, MD Seoul Yangchun-Ku Korea, Republic of Moderator(s): J David Blaha, MD Ann Arbor MI Craig J Della Valle, MD Chicago IL Both TKAs with OxZr or CoCr femoral component in 100 patients had excellent clinical and radiographic results. In both groups, PE wear performance was similar. We hypothesized that clinical and radiographic results, range of motion, patient satisfaction, complication rate, and polyethylene wear performance would be better in the total knee arthroplasties (TKAs) with oxidized zirconium (OxZr) femoral component than those with cobalt-chrome (CoCr) femoral component. We compared the results of 100 patients (93 women and 7 men; 200 hips), all with osteoarthritis of knee) who received an OxZr femoral component in one knee and a CoCr femoral component in the other. The mean age of the patients was 55.6 years (44-60) ye
