Periprosthetic Joint Infection Revision: Expert Care for Complicated Joint Infections
By Dr. Vinayaraj M. Kelagadi | KOSSIN Care, Bengaluru
A joint replacement can significantly improve mobility and quality of life, but in some cases, an infection can develop around the artificial joint. Known as Periprosthetic Joint Infection (PJI), this is a serious complication that may require specialised evaluation, targeted antibiotic treatment and, in selected cases, revision joint replacement surgery.
Understanding Periprosthetic Joint Infection
Periprosthetic joint infection occurs when bacteria infect the tissues surrounding a joint implant. It can affect knee, hip and other artificial joints and may occur soon after surgery or even months or years later.
Symptoms can include:
Persistent or increasing joint pain
Swelling and warmth around the joint
Redness or wound drainage
Fever or chills in some cases
Reduced joint movement
Difficulty walking or bearing weight
Persistent pain after an initially successful joint replacement
A painful artificial joint does not always mean infection, but unexplained or persistent symptoms should be evaluated by an orthopaedic specialist. Diagnosis may involve clinical examination, blood tests such as CRP and ESR, joint-fluid analysis, cultures and appropriate imaging.
“Treating a joint infection requires a carefully planned approach to control infection, rebuild the joint and restore the patient’s confidence in movement.”— Dr. Vinayaraj M. Kelagadi
When Is Revision Surgery Required?
Treatment depends on factors such as the timing and severity of infection, the condition of the implant, the stability of the joint, the bacteria involved, bone and soft-tissue condition, and the patient's overall health.
For selected early infections, DAIR (Debridement, Antibiotics and Implant Retention) may be considered. In more complex or chronic infections, removal of the infected implant followed by one-stage or two-stage revision surgery may be recommended.
A two-stage revision may involve:
Removal of the infected implant and thorough removal of infected tissue.
Placement of an antibiotic-loaded spacer.
A period of targeted antimicrobial treatment and monitoring.
Reimplantation and reconstruction once infection control and the patient's condition are considered suitable.
The appropriate strategy is individualised rather than being the same for every patient.
Targeted Antibiotic Treatment
Antibiotics are an important part of managing prosthetic joint infection. Whenever possible, cultures are used to identify the causative organism and guide treatment. Depending on the infection and surgical approach, antimicrobial treatment may continue for several weeks or longer under specialist supervision.
Close coordination between the orthopaedic surgeon, microbiology/infectious-disease team and rehabilitation team can help create a comprehensive treatment plan.
Reimplantation and Reconstruction
After infection has been controlled, some patients may require revision arthroplasty to restore joint stability, alignment and function. Revision surgery can be more complex than primary joint replacement because infection and previous surgery may affect the surrounding bone and soft tissues.
Careful reconstruction and structured rehabilitation are therefore important parts of the recovery process.
Restoring Function and Mobility
Successful treatment is not only about clearing the infection. The broader goal is to help the patient regain movement, stability, independence and confidence.
Following revision surgery, rehabilitation may include carefully progressed exercises, muscle strengthening, mobility training and gradual return to daily activities according to the surgeon's recommendations.
Expert Orthopaedic Care for Complex Joint Infections
Periprosthetic joint infection can be challenging, but timely diagnosis and an appropriately planned treatment strategy can make a meaningful difference.
If you have persistent pain, swelling, wound discharge, fever or reduced mobility after joint replacement, seeking an orthopaedic evaluation is important.
