Zimmer NexGen knee replacement causes lawsuit

Zimmer NexGen knee replacements have been linked to causing a high number of problems such as pain, loosening of the device and failure of the implant, causing repeat surgeries in individuals requiring knee replacement surgery.

A group of knee surgeons performed a study and presented their data in March 2010 which states that nearly 9% of patients who received the Zimmer NexGen CR-Flex Porous Femoral component were in need of revision knee surgery within two years, while 36% reported looseness of the replacement knee implant.

By September of 2010, several components of the knee replacement were recalled due to manufacturing and design defects. Such defects include the tibial component failing to properly remain connected to the cement which bound it to the bone. Over 68,000 knee replacements were recalled while 114 reports were filed regarding problems with the device.

A new study highlighting potential problems with the Zimmer NexGen knee replacements will be presented to a group of orthopaedic surgeons in an attempt to explain why a number of implants fail.

Between 2000 and 2011, 1,373 knee replacements were examined where a tibial component was used. This component is believed to be the cause for the implants failure. Researchers found that 4% of implants failed which used this component.

The manufacturer of the Zimmer NexGen knee replacement system is currently being sued by about 200 individuals who claim to have suffered complications after having knee replacement surgery. Similar allegations have been raised in these lawsuits claiming that complications caused by the knee replacement system required revision surgery to have the implant replanted.

The U.S. Judicial Panel on Multidistrict Litigation ordered all Zimmer NexGen knee replacement lawsuits be transferred to Judge Pallmeyer in the U.S. District Court for the District of Northern Illinois and consolidated for multidistrict litigation purposes.
