What are the signs of a defective knee implant?

Knee replacement implants are touted as being able to offer a reduction in pain, an improved range of motion, and increased mobility for patients suffering from debilitating conditions such as rheumatoid arthritis, osteoarthritis, osteonecrosis, and post-traumatic degenerative problems.

Total knknee_xrayee replacement surgical procedures are extremely popular, with more than 600,000 performed each year in the United States, according to the Centers for Disease Control and Prevention (CDC). Unfortunately, for some patients who undergo total knee replacements, the promise of an end to chronic pain and a return to a more active lifestyle just doesn't hold true.

Recently, patients implanted with knee replacement devices from manufacturers such as DePuy Synthes, Zimmer Biomet, Stryker Corporation, Wright Medical Group, and others reported serious complications and unusually high rates of failure. While research indicates implants last for approximately 20 years for 80-to-90 percent of total knee replacement patients, others report problems with their prosthetic joints as soon as a few months after surgery.

If you've had total knee replacement surgery, here's what you need to know.

Defective Knee Implant Signs and Symptoms

Discomfort and swelling that occurs immediately after a total knee replacement—and up to three months later—can be completely normal. However, pain and discomfort that appears out of nowhere or increases in intensity may be caused by something more insidious. Watch for the following signs and symptoms, which could indicate that knee replacement implants are defective or have failed:

  • Severe pain in and around the knee joint
  • Feelings of warmth or heat around the knee joint, which may be accompanied by redness of the skin
  • Swelling and inflammation of the tissue surrounding the replacement knee joint
  • Joint instability, such as feeling like the knee will give way if forced to bear weight
  • Infection in the joint or at the surgical site which may present as a fever, or unusual warmth in the knee joint
  • Stiffness in the joint
  • Severely reduced mobility
  • Limited range of motion

Revision and Reconstructive Surgeries

When a knee replacement implant fails, a doctor may suggest a revision surgery that involves removing the defective implant and replacing it with a new one. Defective knee replacement devices can harm the surrounding bone and tissue, and removing the failed prosthesis might cause additional damage. Depending on the severity of the damage, surgeons may have to perform a reconstructive procedure—such as grafting bone, or adding screws or metal wires—before they can place the new knee replacement implant.

Not only are revision and reconstructive surgeries much more painful, invasive and complex than an initial knee replacement, but they also have lower rates of success. Having revision and reconstructive surgeries also exposes knee replacement patients to surgical risks such as blood clots and infection.

What to Do If You Suspect Your Knee Implant Is Defective

Patients who notice signs and symptoms that could potentially indicate a defective knee replacement implant should contact their doctor right away. It's important to assess the extent of the damage as soon as possible. To that end, doctors may order a battery of diagnostic tests, such as X-rays, an MRI, a CT scan and lab tests to screen for infection.

If the knee replacement failure resulted in significant medical bills, pain and suffering, and other losses, the patient may also benefit from seeking the advice of a knowledgeable personal injury attorney with experience handling defective medical device cases.
