Joint replacement surgeries—such as hip or knee replacements—are highly successful in restoring mobility and reducing pain. However, in some cases, patients may develop prosthetic joint infections (PJI). These are rare but serious complications that require prompt diagnosis and treatment.
Dr. Preeti Ajapuje, Consultant in Infectious Diseases, HIV, TB, and Post-Transplant Infections in Koregaon Park, Pune, specializes in the prevention and management of complex infections, including those linked to joint replacement surgeries.
What Are Prosthetic Joint Infections?
A prosthetic joint infection occurs when bacteria or fungi attach to the artificial joint (prosthesis). Unlike regular infections, PJI can form biofilms—a layer of microorganisms that protect themselves and make treatment more challenging.
Causes of Prosthetic Joint Infections
These infections can develop due to:
- During Surgery: Contamination at the time of implant placement.
- Post-Surgery: Infection from surgical wounds or surrounding tissues.
- Hematogenous Spread: Bacteria traveling from another infection site (e.g., urinary tract or dental infection) to the joint implant.
- Weakened Immunity: Patients with diabetes, HIV, kidney disease, or those on long-term steroids or immunosuppressants are at higher risk.
Symptoms of Prosthetic Joint Infections
Patients should watch for:
- Persistent joint pain and stiffness
- Swelling or warmth around the joint
- Redness or wound discharge
- Fever and general fatigue
- Joint instability or difficulty bearing weight
Prevention of Prosthetic Joint Infections
Hospitals and specialists take multiple steps to reduce risk:
- Strict Sterile Surgical Protocols – Maintaining sterile environments during surgery.
- Antibiotic Prophylaxis – Giving antibiotics before and after surgery to prevent infection.
- Optimizing Patient Health – Controlling diabetes, stopping smoking, and treating existing infections before surgery.
- Post-Operative Care – Regular wound checks, dressing changes, and early detection of infection signs.
- Dental and Skin Care – Treating any dental or skin infections promptly to prevent spread.
Modern Treatment Approaches
Treatment depends on the severity, timing, and type of infection:
- Antibiotic Therapy – Targeted antibiotics based on culture reports.
- Debridement with Implant Retention (DAIR) – Cleaning the infected area while retaining the prosthesis, possible in early-stage infections.
- One-Stage Revision Surgery – Removing and replacing the prosthesis in a single surgery.
- Two-Stage Revision Surgery – Prosthesis is removed, infection treated, and a new prosthesis placed after recovery.
- Suppressive Antibiotic Therapy – In patients unfit for surgery, long-term antibiotics may help control infection.
Role of an Infectious Disease Specialist
Prosthetic joint infections require multidisciplinary care between orthopedic surgeons and infectious disease experts. An infectious disease specialist like Dr. Preeti Ajapuje ensures:
- Correct diagnosis with advanced tests
- Tailored antibiotic regimens to combat resistant bacteria
- Guidance on surgical vs. non-surgical options
- Preventive strategies for patients undergoing joint replacement
