DePuy Knee Replacement Lawsuits

A knee replacement manufacturer promised patients relief from pain, but its device caused more misery than it cure

DePuys Various Knee Replacement Devices Have a High Rate of Failure

People from all walks of life find themselves in need of a knee replacement as a result of a variety of issues. It could be that the individual was an active athlete, or arthritis has taken its toll on the joint. Eventually the pain gets to a point where a trip to a surgeon becomes necessary to repair the damage and replace the components of the joint. A knee replacement is made from materials that are designed to attach to the existing bone, wearing for decades before a problem arises again. But for those who received any number of DePuy knee replacement devices, the future is not so bright.

Knee replacement devices have to fit precisely into the existing leg bones and the area of the knee that is being replaced. It is a tricky area to work on due to all of the parts that have to come together for function to be restored. The replacement has to provide a reasonable range of mobility as well as support the weight of the individual. Those who received DePuy knee replacement devices initially gained all of these aspects, but they were lost in a matter of a few short years.

These defective devices are on the market due to an FDA loophole that allows a previously existing device to be altered, then marketed without much oversight from the FDA. The process is known as the 510(k) approval process, and DePuy repeatedly abused it. Faulty knee replacements made their way onto the market because of DePuy’s greed. Little testing was done on the altered devices because it wasn’t required by the FDA. As a result, patients received the defective parts in their body, only to suffer later.

The latest blow to DePuy comes in the form of an FDA issued recall for the LPS Diaphyseal Sleeve. The sleeve receives the tapered ends of the knee replacement that leads into the femur and tibia. It was found that the sleeve does not have enough strength to handle the loading of weight as the individual moves. The failure of the sleeve is known to directly result in bone fractures and loosening of the device

What Happens When the Knee Replacement Fails

There are distinct sensations that are experienced when the replacement starts to fail. Experiencing any one of these sensations or symptoms means that a visit to the doctor needs to be the next stop. The known symptoms are:

  • Pain with no explanation. Pain can range in intensity from a little soreness to an acute shock during a stride. It can also be a pulsing or throbbing pain when idle.
  • Heat in the joint. A reoccurrence of heat long after the surgery means something is wrong with the joint.
  • Unexplained swelling in the joint. The various structures in the knee are responding to the deterioration of the implant with excess synovial fluid.
  • Knee does not support weight, or has a feeling of giving out when standing or walking. This is a clear sign that something has gone wrong with the implant.

When any of these signs occur, the joint is most likely failing, and needs remediation or replacement.
