Despite the overall high success rate in knee replacement surgeries, patients may still experience problems if their knee replacement device is defective. Problems defective knee implants may include loosening of the tibial component at the implant-cement interface. Affected patients often present with pain on weight bearing, swelling, and decreased range of motion. We are currently investigating cases involving individuals who have undergone revision surgery due to loosening after a knee replacement.

Knee replacements can improve quality of life

The knee is made up of a complicated set of tendons, muscles, ligaments and bones. When the joints become damaged by either progressive arthritis, trauma or other ate destructive diseases of the joint, it can cause severe pain that limits everyday activities or even moderate to severe pain while resting during the day or night. In these circumstances, knee replacement surgery can help restore quality of life.

More than 700,000 total knee replacement surgeries are performed each year in the United States, according to the American Academy of Orthopaedics, and nearly 90 percent of patients who undergo knee replacement report a dramatic reduction of knee pain following surgery. Knee implants allow for normal activities and motion, and typically last 15 to 20 years or more.

There are more than a dozen manufacturers of artificial knee implants.

When a Knee Implant Fails

Knee implants are designed to last 15 years or more. When unexpected loosening of the tibial plate occurs, it causes extreme pain and swelling. Often, painful revision surgery is required to remove and replace the device. Complications of revision surgery include bone loss, muscle damage, nerve damage and infection.

Signs of knee implant failure include:

  • Instability when standing, or the feeling like the knee is going to give out backwards or sideways.
  • Popping, clicking or crunching sounds coming from the implant.
  • Heat or warmth around the knee joint.
  • Joint pain and/or swelling.
  • Decreased range of motion.
