Evidence of High Failure Rate in Zimmer Nexgen Cr-flex Porous Femoral Knee Replacement System

It is estimated that about 21 million people in America deal with osteoarthritis, which leads to deterioration of the ligaments in the knee and results in the bones in the knee rubbing against each other. Osteoarthritis can be a very painful and uncomfortable condition and sufferers typically seek out replacement of the joint in order to regain the range of motion that has been lost. When Zimmer began marketing the NexGen CR-Flex Porous Femoral knee replacement system in 2003, it asserted that patients who undergo the procedure to implant the NexGen CR would be able to regain much of their active lifestyle that was lost to osteoarthritis. It was the newest and best of the Zimmer knee models.
Unfortunately, there have been some issues with the implementation of the Zimmer NexGen CR-Flex in a significant amount of patients who have undergone the procedure. In March of 2010, a group of knee surgeons from the Rush University Medical Center in Chicago presented a study to the American Academy of Orthopaedic Surgeons’ annual conference detailing their findings. The study covered the two year results of 108 knee replacement surgeries implementing the NexGen CR-Flex Porous Femoral knee replacement system, and the results were startling. Researchers concluded that over 8% needed a second surgery to revise the implementation and found evidence of loosening in 36% of the patients.
While this is just one of several studies that have been conducted, the results of the Rush University study revealed strong evidence that the failure rate for the NexGen CR-Flex is higher than industry accepted levels. There has been no FDA Zimmer knee recall model as of yet but if more evidence begins to accumulate, then it will be interesting to see how Zimmer reacts.
This is not the first time that Zimmer has dealt with criticism for problems with one of their products. Back in 2008, it was found that their Durom Cup hip implants caused complications in the patients who had the model used in their hip replacement surgery. After the company acknowledged the high failure rates with the Durom Cup, a temporary recall was issued in July of 2008.
While there have not been any any public statements regarding recalls with Zimmer knee models, there is potentially one around the corner. If you have had Zimmer CR-Flex knee replacement surgery and have subsequently had your replacement knee revised or have had other issues such as loosening, pain, or difficulty walking, then you may have the basis for a Zimmer NexGen CR-Flex lawsuit. The attorneys at Rottenstein Law Group have more than 25 years of experience helping their clients recover the money they deserve from negligent corporations.

Hyperbaric Oxygen Therapy Brings Hope To Children With Autism Symptoms

Recent studies in the medical world, on autism symptoms and autism treatment, bring not only hope, but actual help, to families with autistic children. Lead physician and researcher, Daniel Rossignol, M.D., treats children with autism. Seeing his patients improve with hyperbaric oxygen treatment led him to conduct the first large scale, double-blind, controlled study to examine the effectiveness hyperbarics for autism treatment. And, the results of this study demonstrate positive improvements.

What happens in the HBOT Chamber –

Hyperbaric oxygen therapy traditionally involves inhaling up to 100% oxygen at a pressure greater than 1 atmosphere (atm) in a pressurized chamber. In the first randomized, controlled, double-blind multicenter trial, published in BMC Pediatrics and entitled “Hyperbaric treatment for children with autism: a multicenter, randomized, double-blind, controlled trial.” Dr. Rossignol and colleagues, from 6 centers in the USA, studied 62 children, aged 2-7 years, to assess the efficacy of hyperbaric oxygen treatment in children showing autism symptoms.

The research trial concludes that children with autism who received hyperbaric for autism treatment in HBOT Chambers at 1.3 atmospheres and 24% oxygen for 40 hourly sessions had significant improvements in overall functioning, receptive language, social interaction, eye contact, and sensory/cognitive awareness compared to children who received slightly pressurized room air.

The children were randomly assigned to either 40 hours of hyperbaric treatment at 1.3 atm and 24% oxygen (treatment group) or slightly pressurized room air at 1.03 atm and 21% oxygen (non-treatment group). Clinical outcomes were evaluated by three different scales: the Clinical Global Impression (CGI) scale, the Aberrant Behavior Checklist (ABC), and the Autism Treatment Evaluation Checklist (ATEC).

Dr. Rossignol said, “In our study, we observed significant improvements in several core autistic behaviors with the use of hyperbaric oxygen therapy treatment at 1.3 atm compared to children receiving near-placebo treatment. These findings confirm what we are seeing in clinical practice–that many children with autism may benefit with the use of this treatment.”

Director of the International Hyperbarics Association, Shannon Kenitz, said, “With autism on the rise, it is promising to see a study that has been conducted with the high standards endorsed by the medical community. Having this scientifically controlled and analyzed study that shows the positive effects of hyperbarics is truly what this community has needed. The study not only presents the benefit of Hyperbaric Oxygen Therapy for children with autism, but also gives families the hope that so many other therapies have failed to do.”

“The impact of this study on the autism community is significant. It brings validity to a successful intervention that needs to become part of mainstream medicine,” commented Kyle Van Dyke, M.D., and Autism Specialist from Madison, Wisconsin.

The growing concern regarding autism in this country is reinforced by the critically high ranking this study as earned by BMC Pediatrics. It is currently the most accessed article and projected to continue to climb in significance.
