History of Zimmer Knee Products

Knee replacements are hardly a new arrival on the American medical product market – with many models emerging as early as the 1970s. Thereafter, Zimmer began introducing its knee replacement products to the market, followed by its NexGen series in the mid-1990s. Despite increasing criticism from patient advocates, many of Zimmer’s products were “fast-tracked” through the FDA testing procedures under Section 510(k) of the Food, Drug and Cosmetic Act.

Section 510(k), also known as “Pre-Market Notification,” is a procedure wherein a derivative of a previously-approved medical device can receive FDA approval for sale and use with patients despite not having endured full FDA testing and research. Within the purview of total knee replacement devices, the Zimmer NexGen CR-Flex is one of several Zimmer products having received a fast-tracked approval from the FDA, potentially exposing hundreds of thousands of orthopedic patients to a dangerously unstudied medical device.

Concerns over the Zimmer NexGen CR-Flex

The Zimmer NexGen CR-Flex, despite receiving a fast-tracked approval for sale by the FDA, has not gone without scrutiny – a non-peer reviewed report by Dr. Richard Berger of the American Academy of Orthopedic Surgeons was cited in the New York Times as exposing the potential dangers of this surgical implant.

According to his report, entitled “The High Failure Rate of a High-Flex Total Knee Arthroplasty Design,” Dr. Berger expressed concern over the CR-Flex model after studying 108 patients and finding the following:

  • 36 percent of patients showed signs of radiographic loosening
  • 8.3 percent of patients were in need of revision surgery within two years of the original implantation
  • One percent had a revision surgery pending

More specifically, Dr. Berger expressed concern over the porosity of the CR-Flex model, which uniquely does not use cement to adhere to the patient’s bone. Dr. Berger concluded that the NexGen knee had a tendency to disengage once implanted in patients, eventually coming loose, negatively impacting patient mobility and quality of life.

According to reports from patients, the Zimmer NexGen CR-Flex model is associated with any of the following problems:

  • Overall loosening of the components within the knee replacement system
  • Fracture or dislocation of the implant
  • Release of debris due to wear and tear
  • Misalignment
  • Corrosion

Medical interventions necessary to correct the problems allegedly caused by the Zimmer NexGen CR-Flex model have varied, and range in severity, invasiveness, and recovery time.

While it may be possible for some patients to avoid the hassles of a major follow-up procedure, an alarmingly high number of patients have needed revision surgeries, including a complete replacement of the knee implant.

Knee Replacement Recalls

Despite the widespread issues reported with the Zimmer NexGen CR-Flex model knee replacement product, the FDA has not issued a general recall of the product. However, the FDA has taken notice of several potentially problematic Zimmer knee components, including:

  • NexGen MIS Tibial components: Voluntarily recalled by Zimmer
  • NexGen LPS System: Only a few hundred recalled by Zimmer due to possible manufacturing defects
  • NexGen TM Tibial trays
  • NexGen Modular Plates and Keels

Pursuing a Lawsuit

If you are ready to pursue your dangerous medical device lawsuit, you will undoubtedly be best-served by working with a Zimmer knee attorney from start to finish.

In addition to providing steady advice and counsel throughout the duration of your claim, a Zimmer knee lawyer at Eisbrouch Marsh will help you by:

A Zimmer knee lawsuit can help you recover some of what you lost as a result of a faulty medical product.
