Statistical Conclusions of National Joint Registry for England and Wales Data Align With Rottenstein Law Group Hip Replacement Client Data


(New York, NY, September 20, 2011) The Rottenstein Law Group, which represents clients with claims stemming from the surgical implantation of hip replacement devices manufactured and sold by DePuy Orthopaedics and other companies, has evaluated the conclusions of the 8th Annual Report of the National Joint Registry for England and Wales, comparing them to the firm’s own client records and found that the data do indeed correspond.
The National Joint Registry (NJR) of England and Wales was established in 2002 in order “to define, improve and maintain the quality of care of individuals receiving hip, knee and ankle joint replacement surgery across the [National Health Service in the United Kingdom] and the independent healthcare sector”, according to the group’s Web site. The 8th Annual Report of the NJR is the “formal public report for the period 1st April 2010 to 31st March 2011,” according to the front matter of the report itself.
Among other information contained in the report is the following, regarding revision – defined as an “operation performed to remove (and usually replace) one or more components of a total joint prosthesis for whatever reason” – and metal-on-metal joint replacement systems: “[T]he risk of revision for metal-on-metal and resurfacing prostheses was considerably higher than those for other bearing surfaces. Metal-on-metal was close to the revision rate for resurfacing (also metal-on-metal) up to six years after surgery but then appears to overtake the resurfacing revision rate. This is because of a sharp increase in the risk of revision at around six years for the metal-on-metal group.”
The Rottenstein Law Group acknowledges that the largest part of those individuals contacting the firm seeking representation stemming from the implantation of a hip replacement device received a metal-on-metal implant – either a DePuy ASR or Pinnacle, or a device from another manufacturer. In August, 2010, DePuy, a division of Johnson & Johnson, announced a worldwide recall of the ASR Hip Resurfacing System and the ASR Acetabular System. Both units replaced a worn or weakened part of the hip. Many orthopedic doctors believe that the units were poorly designed; the implants can generate debris with wear and tear, causing inflammation and tissue damage in those patients implanted with the devices. The ASR devices were used in 93,000 recipients worldwide.
More recently, issues have been uncovered stemming from complications with DePuy’s Pinnacle hip implants. In May federal actions against DePuy and Johnson & Johnson concerning the Pinnacle hip replacement system were consolidated for pre-trial proceedings in multidistrict litigation. Plaintiffs in these suits allege that the Pinnacle system was poorly designed and/or that DePuy failed to provide adequate warnings concerning the Pinnacle, specifically with regard to the possibility that the Pinnacle, a metal-on-metal hip implant, is prone to shed metallic particles into recipients bloodstreams and tissues.
The Rottenstein Law Group maintains a Web site with information about DePuy’s recalled hip implants. The site features easy to use social media features that allow for easy sharing of information on sites like Facebook and Twitter.
