Defective Knee Replacement Implants

 

Knee replacement surgery is a very common procedure and can make a huge difference in the quality of life for someone suffering from chronic knee pain. Recently, however, many brands of the knee or hip implants are going bad years earlier than expected. Some are failing after shortly after the procedure. Companies that make knee implants originally designed them for short-term use in elderly patients who had a shorter life expectancy. Baby boomers and younger patients who had the knee or hip replacement surgeries expected their implants to last decades. In many cases, there is little research or testing of the knee replacement systems and on their long-term and thousands of patients are suffering complications from the failed knee replaces.

DePuy Attune, Zimmer, Arthrex and Exactech Optetrak knee replacement systems are liked to severe knee replacement side effects. In some cases, patients required revision surgeries or new knee replacement surgery to correct the medical problems created by defective knee replacement devices.

Some of the complications associated with the defective knee replacement devices include:

  • Pain

  • Mobility issues

  • Swelling

  • Instability Problems

  • Infections

  • Fractures

  • Disassociation of implant

  • Inflammation

  • Loosening of implant

  • Change in component position

  • Kneecap moves out of place (also medically termed Patello-Femoral Tracking-Lateral Release)

DEPUY ORTHOPEDICS KNEE REPLACEMENT RECALLS

 

The DePuy Attune knee system is one of the most widely used knee replacement devices on the market today. However, the FDA reports getting complaints of problems with the device that triggered additional painful surgeries. In 2016, two large awards were issued for patients in their DePuy Pinnacle knee replacement lawsuits. In one, a jury in Texas ordered DePuy to pay more than $1 billion to a group of six patients, who claimed they suffered injuries as a result of their DePuy Pinnacle implant. That same year, another Texas jury awarded almost $500 million to five plaintiffs in their Pinnacle lawsuit.

Reasons given to the FDA for the knee implant failure include:

  • Failure to bond

  • Worn components

  • Fracture

  • Metal debris shedding

  • Loss of the bone’s attachment with the implant

The Food and Drug Administration (FDA) issued a recall in June 2015 of the Attune knee tibial articulation surface instruments. Attune knee tibial Articulation Surface Instruments. A small wire spring coil, or Balseal, which is part of the instrument, is used during the knee replacement surgery to test the range of motion of the implant to make sure that the tibia is in the right location.

Attune knee implant patients have also complained of severe pain and knee implants that fail only a couple of years after the knee replacement surgery. According to reports, the early failure is caused by the tibial baseplate becoming loose, causing pain, infection, inflammation and other injuries to the surrounding bone or muscle.

ZIMMER PERSONA KNEE REPLACEMENT

 

The FDA issued a Class 2 Recall Notice for the Zimmer Persona tibial plates in 2015. More than 12,000 of these potential defective knee replacement devices were used in surgeries over the years.

Similar to other metal on metal knee replacement devices, patients who received a defective Durom Cup replacement experienced serious and painful side effects such as:

  • Pain in the hip, groin or thigh

  • Inflammation or swelling

  • Death of the tissue in the joint

  • Loss of surrounding bone

  • Metal Poisoning or metallosis

Several recalls have been issued by knee implant makers over defects in either the design or construction of the implants. Three companies that have issued recalls of their knee implants are DePuy (Attune knee implant), Arthrex, and Exactech.

ARTHREX KNEE REPLACEMENT DEVICE FAILURE

 

Arthrex issued a recall for its Arthrex iBalance TKA Tibial Tray in December 2015 after discovering a smooth texture on the implants on the outer part of the knee implant. This smooth texture made it incompatible with other with previous models that had a rough texture.

The Arthrex iBalance TKA Tibial Tray is part of the Arthrex iBalance Total Knee Arthroplasty (TKA) System. It was created for the purpose of treating multi-compartmental knee cartilage degeneration caused by osteoarthritis or post-traumatic arthrosis.

The iBalance TKA was marketed by Arthrex as another option besides conventional total knee replacement. Its design is supposed to reduce the need for more surgeries to have metal plates and screws removed.


Knee replacement patients have reportedly suffered from complications after having the iBalance TKA implanted, leading to the need for revision surgery.

EXACTECH KNEE IMPLANT FAILURES

 

The FDA received reports that the Exactech Optetrak knee replacement components were failing prematurely. This knee implant failure was reportedly caused by tibial insert wear and tear of the implant.  Exactech Optetrak knee implant failure has caused several patients to undergo revision surgery to address the adverse side effects.
