Zimmer NexGen Knee Recall | Zimmer Knee Lawyer Pennsylvania

New Lawsuit Alleging Zimmer Knee Failure Filed in Pennsylvania

Shay Morrigan | December 29th, 2011

West Virginia resident David Dicken, as represented by his Zimmer knee lawyer, filed a Zimmer knee failure lawsuit on December 15, 2011, in the U.S. District Court, Western District of Pennsylvania. The plaintiff was implanted with a Zimmer NexGenLPS-Flex femoral component. A few hundred of these components were part of a Zimmer NexGen knee recall in December 2010 due to manufacturing problems, but it does not appear that Mr. Dicken’s implant included one of the recalled components.

Reasons for past Zimmer NexGen knee recall

A Zimmer NexGen knee recall has been issued on only two occasions with regard to very specific components and for equally specific reasons. The first was in September 2010 and involved NexGen TM Tibial Trays, NexGen MIS Tibial Components, and MIS Modular Tibial Plates and Keels, all of which could have been used in the NexGen CR-Flex or the LPS-Flex. This Zimmer NexGen knee recall was issued because of evidence (over 100 incidents reported to the FDA) that these components tended to loosen prematurely.

A second Zimmer NexGen knee recall was implemented in December 2010, but involved only a few hundred femoral components used in the NexGen LPS system. These components contained manufacturing defects which prompted the action.

Zimmer knee lawyer claims plaintiff’s implant loosened prematurely

Similar to those components involved in the first Zimmer NexGen knee recall, Mr. Dicken’s NexGen LPS-Flex femoral component allegedly came loose prematurely. According to the plaintiff’s Zimmer knee lawyer, Mr. Dicken was implanted with a Zimmer NexGen knee system, which included the NexGen LPS-Flex femoral component, on January 11, 2005. Shortly after the implant, he began experiencing severe and debilitating pain, and returned to his physician several times for help.

Eventually, his physician determined that a Zimmer knee failure had occurred, and Mr. Dicken went through revision surgery to revise/replace his knee implant on December 15, 2009.

Zimmer knee failure and high-flex models

According the complaint drafted by Dicken’s Zimmer knee lawyer, studies support a conclusion that a greater likelihood of Zimmer knee failure exists with regard to high flex models.  According to the complaint, “numerous peer-reviewed articles establish that the NexGen LPS-Flex fails to provide…significant added flexion or range of motion to the standard NexGen LPS.”

In 2009, new literature emerged regarding the risk of loosening with high-flex knee implants as well as information regarding flexion and range of motion offered by high-flex models.  A controlled study led by Dr. I. Amed as well as the Wohlrab Study out of Germany both reached similar conclusions: that the advantage in range of motion offered by high flex devices was limited as compared with its standard device counterparts.

Zimmer knee lawyer seeking liability and negligence

In his Zimmer knee failure lawsuit, Mr. Dicken, as represented by his Zimmer knee lawyer, is suing on grounds of liability and negligence, and is seeking damages in excess of $75,000 for past and present injuries, medical expenses, rehabilitation and home care, lost income, permanent disability, and pain and suffering.
