Zimmer Hip/Knee Replacement

  •  Hip & Knee Replacement Medical Record Review & Outsourcing Services

Patients relieved by Zimmer's hip and knee solutions propelled it to become the market leader. The solutions not only provided pain relief, good quality of life of the patient, but it also helped in restoring mobility for a number of patients. The products like femoral (neck and stem) components, acetabular (cup) components and revision surgery systems are manufactured by Zimmer.

The technique of Metasul Metal-on-Metal articulation and Trabecular Metal technology is used in manufacturing these implants which are capable of providing a good level of friction resulting in faster joint stabilization. But there was a major issue encountered because of the metal grounding on metal as it leads to toxic metal shards being released into the patient's surrounding tissues and bone. Gradually, these toxins have resulted in causing inflammation, infection, a decay of soft tissue and bone, severe pain and many other adverse reactions requiring surgery to remove and replace the implant.

The Food and Drug Administration (FDA) approved Zimmer Durom Acetabular Component (commonly known as Durom Cup) in 2006 for the use of total hip replacement to address the durability and range of motion of the joint. Most of the Zimmer Holdings Inc. came to the market after going through the FDA’s 510(k) clearance process. The young patients with more physical lifestyle were targeted and implanted, and it was observed it lead to serious injuries within a short time.

Serious Alleged Injuries may include:

  • Premature loosening
  • Severe pain
  • Inflammation and swelling
  • Limited mobility
  • Infection
  • Bone, joint, muscle or neurological damage
  • Shedding of metal debris into the bloodstream
  • Metallosis (the build-up of metal ions in the body)
  • Component corrosion
  • Popping, crunching or other noises from the hip caused by movement
  • Fractures of one or more components


Zimmer Holdings Inc. was targeted by the FDA as several reports of adverse events and complications related to the NexGen Flex Knee as well as Durom Cup were noted. In September and December 2010, many implants were recalled. In March 2015, there was a recall for Persona Trabecular Metal Tibial Plate by the FDA. Several patients had to hire knee replacement lawyers. 

Legal Updates:

Many federal cases regarding the Zimmer Durom Cup were transferred to the U.S. District Court for the District of New Jersey on June 9, 2010. Along with Zimmer (which recently purchased Biomet), other companies such as DePuy, Stryker, Wright Medical, etc. are also involved. Each of these come with their related knee replacement class action lawsuits.

Litigation has been filed with regard to the following NexGen models:

  • NexGen Complete Knee Solution (LPS-Flex)
  • NexGen Complete Knee Solution Gender Solutions Female LPS-Flex (GSF LPS-Flex)
  • NexGen Complete Knee Solution Cruciate Retaining-Flex Femoral Components (CR-Flex)
  • NexGen Complete Knee Solution CR-Flex Gender Solutions Female CR-Flex (GSF-Flex)
  • All NexGen MIS Total Knee Procedure Stemmed Tibial Components

Wigenton. Zimmer established a settlement fund of $47.5 million at this time.

In 2011, this federal MDL was formed in the Northern District of Illinois before U.S. District Judge Rebecca Pallmeyer. 1600+ lawsuits were filed at the beginning of this MDL accusing the company of manufacturing defective devices. Many of the cases were dismissed before they could make it to court. As of May 2017, only around 300 cases remain pending in the MDL. As of May 2017, only around 300 cases remain pending in the MDL.
