A failed knee replacement is relatively uncommon, as most people who have had total or partial knee replacements do just fine. In fact, about 95 percent of these procedures go off without a hitch, with the artificial joint lasting between 15 and 20 years. However, sometimes things do go wrong, either because of a poorly designed implant or the natural wear and tear that comes with daily use. Recently, the Attune knee replacement has been in the spotlight due to failures, leading to a recall and redesign of the product.
### Symptoms of a Failed Knee Replacement
If you’ve had knee replacement surgery, there are several signs that might indicate trouble. These include significant pain or swelling in the joint. Crystalline arthropathy is a concern that mimics an infection but is actually caused by crystallization around the failing implant.
Other symptoms to watch out for include losing your balance or feeling unsteady, which could be due to issues with the implant. Metal hypersensitivity is another issue; it can cause a rash around the knee. You might also experience a fever in the knee joint and have a noticeable buildup of fluid around the area.
### Why Does a Knee Joint Fail?
There are a few reasons why knee replacements can fail. Every artificial joint has a limited lifespan, and issues can arise from poorly designed metal joints. Recently, the Depuy Attune knee replacements have been recalled after many patients experienced problems. The main issue was that the bonding failed, causing the joint to detach from the leg bones.
Just like bones, the metal and plastic parts of the replacement knee can break or fracture due to trauma, necessitating a new joint. Additionally, bacteria can adhere to these materials, leading to infection.
If you’re concerned about the stability or safety of your replacement knee joint, it’s essential to consult your surgeon or physician. With a typical lifespan of 15 to 20 years, these joints eventually wear out. Regular check-ups can help ensure your joint is functioning correctly and address any issues early on.
