A 2013 article titled “Clinical and radiographic outcomes of 139 hips with articular surface replacement total hip arthroplasty*.” published in The Israel Medical Association Journal by A. Kadar et al. examined 139 uses of the Articular Surface Replacement (ASR; DePuy Orthopaedics Inc.) in a particular clinic and evaluated health outcomes and implant vitality.
Kadar et al. write “Between 2007 and 2010 139 hips were operated on and evaluated in our clinic. All patients underwent a clinical interview, function and pain evaluation, as well as physical examination and radiographic evaluation. When necessary, patients were sent for further tests, such as measuring cobalt-chromium levels and magnetic resonance hip imaging.”
While this small study did not show an excessively-high rate for revision surgery, this research team found that “For patients who required further tests, clinical and radiographic outcomes were significantly poorer than for the rest of the cohort. Average blood ion levels were high above the normal (cobalt 31.39 ppb, chromium 13.32 ppb), and the rate of inflammatory collection compatible with pseudotumors on MRI was 57%.”
Due to the fact that DePuy Orthopaedics, Inc. failed time and again to warn users of the risk for elevated blood metal ion levels associated with the ASR/ASRXL metal-on-metal hip replacement systems, a number of
DePuy ASR hip replacement lawsuits have been filed. If you or loved one used a metal-on-metal hip replacement system and suffered elevated blood metal ion levels, premature device failure, or another ASR complication, you may be entitled to significant financial compensation.
