What causes PJI?
Coagulase-negative Staphylococcus species can cause PJI at any time after an arthroplasty has been placed. This group of organisms is the second most common cause of early-onset PJI, in which the presentation typically includes wound drainage, local skin changes, and pain.
What bacteria causes prosthetic joint infection?
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.
What happens if you get an infection after knee replacement?
If a knee replacement infection goes deeper than the skin and tissue around a joint, it may need to be treated surgically. Surgical treatment options include: Debridement: This is a surgical washout of the joint. Any contaminated soft tissue is removed, and the artificial joint is cleaned.
How do you treat PJI?
In the United States, chronic PJI has been mainly treated via two-stage exchange arthroplasty with a 4 to 8 week course of IV antibiotics in between the two stages. However, this surgical strategy is now described as initial treatment for some acute postoperative or acute hematogeneous PJI.
How is PJI diagnosed?
Despite significant progress in recent years, the diagnosis of periprosthetic joint infection (PJI) remains a challenge and no gold standard test exists. A combination of serological, synovial, microbiological, histological, and radiological investigations is performed that are expensive, often invasive, and imperfect.
How is a prosthetic joint infection treated?

Can prosthesis get infected?
Prosthesis-related infection is a serious complication for patients after orthopedic joint replacement, which is currently difficult to treat with antibiotic therapy. Consequently, in most cases, removal of the infected prosthesis is the only solution to cure the infection.
How long do you treat a prosthetic joint infection?
Antibiotic therapy duration for prosthetic joint infections treated by debridement and implant retention (DAIR): similar long-term remission for 6 weeks as compared to 12 weeks.
How common are prosthetic joint infections?
The current rate of prosthetic joint infection varies from one center to another but typically range between 0.5% to 1.0% for hip and shoulder replacements, and 0.5% to 2% for knee replacements [10][11]. Infection rates are higher in the first 2 years compared to after two years following surgery.
