Your question: Why do prosthetic joints get infected?

How does prosthetic joint infection occur?

Initiation of Infection. The majority of PJIs occurring within 1 year of surgery are initiated through the introduction of microorganisms at the time of surgery. This can occur through either direct contact or aerosolized contamination of the prosthesis or periprosthetic tissue.

Why do artificial joints get infected?

Artificial joints can become infected by bacteria. Bacteria may infect the artificial joint during or after surgery, causing infection. Symptoms may include pain, swelling, and limited range of motion.

Can a prosthetic get infected?

Infection is the most serious complication of joint replacement. Infection occurs in approximately 0.8 to 1.9 percent of knee replacements and 0.3 to 1.7 percent of hip replacements. Approximately 1 to 2 percent of prosthetic hip or knee replacements develop infection over the lifetime of the prosthetic joint.

How is a prosthetic joint infection treated?

Prosthetic joint infection usually requires combined medical and surgical therapy. While revision surgery is widely considered to be the gold standard surgical procedure, debridement, antibiotics and irrigation with implant retention is a very appealing alternative.

What is prosthesis disease?

Prosthesis infections are mainly initiated by perioperative contamination with bacteria or via the hematogenous route during postoperative bacteraemia, resulting in prosthesis colonization and subsequently infection [13,18]. From: Management of Periprosthetic Joint Infections (PJIs), 2017.

What bacteria causes prosthetic joint infections?

Most prosthetic joint infections are the result of bacteria—often Staphylococcus aureus—present in the body or introduced during the surgery itself or subsequent procedures.
