periprosthetic joint infection

Periprosthetic joint infection is a bacterial infection that occurs as a complication following joint replacement surgery. It primarily affects individuals who have undergone primary arthroplasty and can result in significant joint pain and reduced function if not promptly addressed. This condition is estimated to occur in approximately 1% to 2% of primary joint replacements. Early identification and tailored management are crucial to preserving joint function and improving outcomes.

Patients with periprosthetic joint infection may experience localized joint pain, swelling, warmth, and sometimes fever. In certain cases the signs of infection might be subtle, making it challenging to differentiate from other post-surgical complications. Symptoms can appear acutely soon after surgery or develop more gradually over time. Not all individuals experience all features, and the severity of symptoms varies considerably.

Periprosthetic joint infection results from bacterial contamination that occurs during or following joint replacement surgery. The infection is an acquired complication and is not linked to any inherited genetic factors. Bacteria may enter the joint during the surgical procedure or postoperatively, subsequently colonizing the prosthesis and surrounding tissues.

Currently, management focuses on supportive care and symptom management, with treatment plans tailored to the individual. A multidisciplinary team typically addresses periprosthetic joint infection through antibiotic therapy and, when necessary, surgical interventions such as debridement or prosthesis revision. Although there are no treatments specifically approved for this condition, there are several orphan drug designations under investigation. Patients are encouraged to discuss treatment options with their healthcare team to determine the most suitable approach for their situation.

The course of periprosthetic joint infection varies widely and depends on factors such as the severity of the infection, the bacterial strain involved, and how quickly effective treatment is initiated. With current standards of care many patients experience stabilization of symptoms and preservation of joint function, although some cases may require additional surgical intervention. Outcomes described in medical literature continue to evolve as standards of care improve. Families often find it helpful to connect with orthopedic and infectious disease specialists for support and further guidance on managing recovery.

Periprosthetic joint infection remains an active area of research with numerous ongoing clinical trials investigating new treatment strategies and interventions to improve patient outcomes. Individuals interested in exploring clinical trial options are encouraged to search ClinicalTrials.gov or consult with their healthcare team regarding eligibility.
