Prosthetic Joint Infection: Causes, Risks, and What You Need to Know
When a prosthetic joint infection, a bacterial infection that develops around an artificial joint like a hip or knee replacement. Also known as periprosthetic joint infection, it’s one of the most serious complications after joint replacement surgery. It doesn’t happen often, but when it does, it can ruin years of progress—pain, swelling, and even implant failure follow fast. About 1 to 2 out of every 100 joint replacements get infected, and those numbers rise if you’ve had prior surgery, diabetes, or a weakened immune system.
These infections usually start with bacteria entering the body during surgery or later through a cut, dental work, or urinary tract infection. Staphylococcus aureus, a common skin bacterium that’s responsible for most prosthetic joint infections is the usual culprit. But other bugs like Staphylococcus epidermidis, a slower-growing germ that sticks to implants and hides from antibiotics are tricky—they form biofilms that make treatment harder. You might not feel sick at first, but if you notice new pain, warmth, or drainage near your implant, don’t wait. Delaying care increases the chance you’ll need more surgery.
Doctors use blood tests, fluid samples from the joint, and imaging to confirm the infection. Treatment isn’t simple. Sometimes, a few weeks of strong antibiotics can clear it. But often, you’ll need a two-stage revision: remove the infected implant, clean the area, wait for the infection to vanish, then put in a new one. In some cases, the implant stays in, but you’ll be on lifelong antibiotics. The key? Catch it early. The longer it sits, the harder it is to fix.
This collection of articles doesn’t just talk about infection—it digs into what makes some people more vulnerable, how antibiotics work (or don’t) against biofilms, and what lifestyle changes can lower your risk. You’ll find real advice on spotting warning signs, understanding test results, and navigating treatment choices without getting lost in medical jargon. Whether you’re a patient, caregiver, or just trying to understand what went wrong after surgery, these posts give you the clear, practical info you need.
