Periprosthetic Infection – Managing Infections After Joint Replacement

At The Fracture & Orthopaedic Clinic, we specialize in the diagnosis and treatment of periprosthetic infections, a serious complication that can occur after joint replacement surgery. Our expert team, led by Dr. Srinivasan K, Dr. Shankar R. Kurpad, and Dr. Kamini Kurpad, provides advanced infection control strategies and surgical interventions to help patients regain mobility and prevent implant failure.

What is Periprosthetic Infection?

A periprosthetic infection (PPI) is an infection that develops around an artificial joint (prosthesis). It can occur shortly after surgery (acute infection) or develop months to years later (chronic infection). Early detection and treatment are essential to prevent further complications.

Causes of Periprosthetic Infection

• Bacterial Contamination – During or after surgery.
• Bloodstream Infections (Hematogenous Spread) – Bacteria from another infection in the body.
• Poor Wound Healing – Inadequate recovery or post-surgical complications.
• Weakened Immune System – Conditions like diabetes, cancer, or autoimmune disorders.
• Prior Joint Surgery or Implant Failure – Increases infection risk.

Symptoms of Periprosthetic Infection

• Persistent Pain – In the replaced joint, even after recovery.
• Swelling & Redness – Around the surgical site.
• Increased Warmth & Tenderness – In the affected area.
• Fluid Drainage from the Wound – May indicate an active infection.
• Joint Instability & Loosening – Causing difficulty in movement.
• Fever & Chills – Suggesting a spreading infection.

Treatment Options for Periprosthetic Infection

1. Non-Surgical Management (Early-Stage Infections)

• Targeted Antibiotic Therapy – Intravenous or oral antibiotics to control infection.
• Joint Aspiration & Lab Tests – To identify the bacterial cause and determine the best treatment.
• Debridement & Implant Retention (DAIR) – Cleaning the infected area while preserving the implant.

2. Surgical Treatment (For Chronic or Severe Infections)

• Single-Stage Revision Surgery – The infected implant is removed and replaced with a new one in a single procedure.
• Two-Stage Revision Surgery – First, the infected implant is removed, and an antibiotic-loaded spacer is placed. Later, a new joint is implanted.
• Arthrodesis (Joint Fusion) – In cases where reimplantation isn’t possible.
• Amputation (Rare Cases) – Only in severe, uncontrolled infections.
