Periprosthetic Joint Infection (PJI): What You Need to Know
What is PJI?
Periprosthetic joint infection (PJI) is an infection that occurs around an artificial joint, such as a hip or knee replacement. It is a rare but serious complication that can affect the success of your joint replacement.
Signs and Symptoms
If you have a joint replacement, watch for the following signs:
Persistent pain or swelling around the joint
Redness or warmth over the joint
Drainage or oozing from the wound
Fever or chills
Difficulty using the joint as usual
Diagnosis
Doctors use a combination of methods to diagnose PJI, including:
Blood tests to check for signs of infection
Imaging, such as X-rays or CT scans, to assess the joint
A sample of joint fluid (aspiration) to test for bacteria
Treatment Options
Treatment depends on the severity and timing of the infection. Options may include:
Antibiotics to treat the infection
Surgery to clean the joint (known as debridement)
In some cases, the joint replacement may need to be revised or removed temporarily
Rehabilitation: physical therapy to regain strength and range of movement
Keep your joint healthy by staying informed and seeking prompt care if you notice any concerning symptoms.
