The Dangers of Knee Replacement Surgery

The Dangers of Knee Replacement Surgery

Millions of Americans suffer from osteoarthritis in their knees, leading to over 790,000 knee replacements being performed every year in the United States. However, knee replacements aren’t actually the permanent fix that they may seem to be. In fact, many patients actually report more pain after their knee replacement than they experienced before the procedure.

Knee replacements can be a good option for some people, but they aren’t the only option for relieving osteoarthritis pain. Along with the possibility of continued or worsened pain after a knee replacement, there are a number of other factors to consider when weighing treatment options for chronic osteoarthritis pain.


Over One Third of Knee Replacements “Medically Inappropriate”

Most knee replacements are performed as a solution for chronic knee pain due to osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. Of those replacements performed every year, about one-third of them are actually classified as ‘inappropriate,’ based on a patient classification system developed and validated in Spain, according to recent research published in Arthritis & Rheumatology.

Dr. Daniel Riddle from the Department of Physical Therapy at Virginia Commonwealth University in Richmond led the study, which examined several criteria that are used to determine if a patient is qualified to receive a knee replacement surgery. Data was collected and analyzed from 205 patients that received knee replacement surgeries.

Researchers found that 34% of the surgeries were deemed medically “inappropriate,” 22% were “inconclusive” as to whether they were appropriate or not, and 44% were appropriate to be performed. Riddle and his colleagues found that the inappropriateness of knee replacement surgery was higher than expected, and also linked to further knee pain and loss of function. Because of these numbers, Riddle stressed the importance of implementing a “patient selection criteria” in the US, as there is currently no scale used to measure if a knee replacement is actually necessary.

Researchers at Virginia Commonwealth University (VCU) published an important study that focused on appropriateness of total knee replacement surgeries. Examining a list of factors designed in Europe to assess surgical validity, the scientists determined that knee replacement surgery should only be used when osteoarthritis was fully developed.

“This means not just severe pain but also impaired physical function,” explained Gretchen Reynolds of the New York Times, “like an inability to climb stairs, get out of a chair or walk without aid.

The VCU team also argued that the replacements were typically a better solution when patients were at least 66 years old, since the artificial knee typically degrades in about 20 years – meaning that surgeries would have to be repeated during the lifetime of younger patients.

Finally, they looked at a previous analysis of 200 adults who were suffering from knee pain and eventually had the joint replaced. One of out every three patients in that study had mild arthritis and were inappropriately selected for the total knee replacement operations, the team found.

With over one-third of knee replacements being considered inappropriate, some cases of knee pain should be treated with a much less invasive and more economic approach.

Knee Replacements Not Permanent Fix

The new metal joint used during knee replacement surgery typically will last between 10 and 15 years. Even with a ‘perfect’ knee replacement, depending on the age of the patient during the procedure, they could potentially need two or more knee replacements in their lifetime. Most knee replacements are done on patients between 50 and 80 years of age, there are often even younger patients recommended for the procedure. Of the over 790,000 Americans who have knee replacement surgery, over 105,000 of those will be back in the OR for a repeat surgery long before 15 years have passed, especially if the patient is obese or extremely active.


Dangers of Knee Replacements

Along with the knowledge that many knee replacements are not really necessary, there are a number of risks that are associated with the procedure. Complications that are associated with total knee replacement surgery include, but are not limited to: anesthesia-related complications, blood clots, and infections.

Anesthesia-related complications - Adverse effects of anesthesia range from nerve injury to vocal cord injury, from latex allergic reactions to dental trauma. General anesthesia may also induce an irregular heartbeat.

Blood clots - Surgery makes it likelier that you will experience a blood clot. “That’s because the clotting process is stimulated as your body attempts to stop the bleeding and close the surgical wound,” said Samuel Greengard of Healthline. “The surgical procedure may stimulate clots to form in error in blood vessels, which then may block the normal flow of blood.”

Infections - Infections are of particular concern to individuals diagnosed with diabetes or rheumatoid arthritis, due to their more vulnerable immune systems.
