Many people who must have a knee replacement are implanted with a Zimmer knee replacement device, made by the popular medical device manufacturer, Zimmer Biomet.
Zimmer Biomet, a publicly traded medical device company located in Warsaw, Ind., manufacturers treatment options for knees, hips, shoulders, elbows, backs, and chests.
Their Zimmer knee replacement device manufacturing is the biggest income generator for the company. In 2016, the Zimmer knee replacement device brought in $2.7 billion in sales which is more than a third of their annual $7.6 billion sales numbers.
Zimmer sells their knee replacement devices under several names including Persona, NexGen, Oxford, and Vanguard. The Persona Zimmer knee replacement device has been under scrutiny as many recipients have suffered from severe complications including the need for revision surgery.
Zimmer Knee Replacement Device
The Persona Zimmer knee replacement device is made up of several components. One of these components, the Persona Trabecular Metal (TM) tibial plate is a part of the Zimmer knee replacement device that is made up of metal. It is implanted into the tibia bone without the use of cement.
This part of the Persona Zimmer knee replacement device has two pegs that are intended to be inserted into the bone so that the bone will grow around it, thus securing the device in place. This gives the Persona Zimmer knee replacement device stability.
However, because of numerous patient reports of major complications, the company instituted a voluntary recall of the TM implant that is part of the Persona knee replacement device.
There are two main problems reported with the Persona Zimmer knee replacement device that led to the recall.
Radiolucent lines are lines that show up in X-Rays and are gaps between the implant and the bone. This may mean that the Zimmer knee replacement device is poorly seated and is moving out of place. Radiolucent lines are a precursor to loosening.
A Zimmer knee replacement device may also become loose. If a knee replacement device becomes loose, it is at risk for failure.
Other problems that patients cite include persistent pain, lack of ingrowth, loss of fixation, globally tight knee, fracture, instability and patella tracking issues.
Many patients need revision surgery to fix the problems they experience with their Zimmer knee replacement device. Revision surgery is costly, dangerous and patients are at risk for additional complications.
Revision surgery patients may experience infection, swelling, pain, nerve or tissue damage, damage to blood vessels, blood clots, bone loss, leg length discrepancies, and fracture.
Reasons for a Knee Replacement
There are many reasons that a patient must get a knee replacement. Knee replacements are done on patients who have experienced extensive damage to their knee joints. Also, knee arthroplasty is done to reduce pain or eliminate pain because of wear and tear on the knee joint. This kind of damage or injury can come from arthritis, aging or other inflammatory conditions.
It is estimated that about 600,000 knee replacement surgeries are performed each year in America.
If you or someone you love has experienced problems due to a Zimmer knee replacement device, you may be eligible for legal compensation.
