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.
