Hip resurfacing procedures have only been performed relatively recently.  As such, there is limited information available regarding the long-term performance of the hip resurfacing implants.  With more information now available, there is a growing body of data with regards to the long-term outcomes of hip resurfacing procedures.

One study followed up recipients of metal-on-metal hip resurfacing implants.  The study was conducted by Harlan Amstutz et al.  and published in the Journal of Bone and Joint Surgery in 2010.  The title of the report is “Clinical and Radiographic Results of Metal-on-Metal Hip Resurfacing with a Minimum Ten-Year Follow up.”  The study was conducted because “There was a need for information about the long-term performance of the modern generation of hip resurfacing implants.”  Therefore, the researchers conducted a retrospective review of the first 100 hip implants of one specific resurfacing design.

The study included 100 implantations conducted by the same surgeon.  The average age of the implant recipients was 49.1 years, with the majority of the patients being male.  All patients were assessed clinically and radiographically.  The average duration of follow-up was 11.7 years.  Two patients did not continue with follow-ups, and five patients died of unrelated causes.   Eleven implants had conversion to total hip arthroplasty: eight because of loosening of the femoral component, one due to femoral neck fracture, one due to recurrent subluxation, and one due to infection.

The researchers concluded “The results of the present series constitute a reference point to which subsequent series should be compared.  These ten-year results in a group of young patients are satisfactory, and the low rate of osteolysis is encouraging, but longer follow-up is required for comparison with conventional total hip arthroplasty.“

Sadly, a number of people have entered into hip replacement surgery unaware of possible complications that may come with metal-on-metal hip implants, and as such, a number of hip replacement lawsuits have been filed.  In particular, a number of lawsuits have been filed against DePuy, the manufacturer of the DePuy ASR™ and DePuy ASR™ XL hip replacement systems (both of which were recalled in 2010), due to the fact that the company is alleged to have known of problems with its products but failed to act.

If you or a loved one used a hip implant by DePuy or another metal-on-metal hip replacement system and suffered negative side effects or hip replacement failure, you may be entitled to significant financial compensation.  For more information, or a free, no-obligation case consultation, contact our team of DePuy ASR hip replacement lawyers at your convenience.  We have the experience, resources, and skills required to win the justice you deserve, even from the largest of medical device manufacturers.
