Detailed Description

Total joint arthroplasty (TJA) is a very common and successful procedure, and is expected to become more prevalent in the upcoming years. However, despite its success, TJA is associated with some complications, including periprosthetic joint infection (PJI). PJI is a devastating complication that is associated with marked patient morbidity and mortality and is an immense economic burden. Although the rate of PJI following a TJA is low, the burden is rising exponentially due to health complications and treatment costs. There are two common types of surgical treatments that can be used to treat chronic PJI, a two-stage exchange arthroplasty and a one-stage exchange arthroplasty. During a two-stage exchange arthroplasty, the implants are removed, infected tissues are debrided and a temporary antibiotic impregnated spacer fashioned from polymethylmethacrylate is placed (stage one). Afterwards the patient undergoes many weeks of intravenous antibiotics, followed by reimplantation at a later date (stage two). During the time between the first and second stage of the revision patients are often immobile, experience severe pain due to a lack of functioning joint, and may experience systemic toxicity associated with the administration of antibiotics. In a one stage exchange arthroplasty, the infected prosthesis is removed, infected tissues are debrided, and a new prosthesis is reimplanted during the same procedure. While the two-stage exchange arthroplasty is the preferred method of treatment for chronic PJI in North America, the one-stage exchange arthroplasty is the method of choice in Europe and some centers have reported comparable results in terms of success for one-stage exchange to two-stage exchange arthroplasty. However, there has been no randomized, prospective, controlled study to date that compares one-stage exchange to two-stage exchange arthroplasty. Because of the lack of comparative outcome reports, and the perceived higher rate of failure of one-stage exchange arthroplasty, surgeons in North America prefer to perform the traditional two-stage exchange arthroplasty for management of chronic PJI. Several teams have succeeded in performing a one-stage exchange arthroplasty in selected patients, but this procedure has not gained much popularity in the US. The purpose of this study is to investigate the outcome of one-stage and two-stage exchange arthroplasty for the management of patients with chronic PJI. The hypothesis of this study is that one-stage exchange arthroplasty, if performed in the appropriate patient population, carries a similar success rate for the treatment of chronic PJI as two-stage exchange arthroplasty and avoids many of the problems associated with two-stage exchange arthroplasty.

Interventions

  • Procedure: One-stage exchange joint replacement surgery
  • Procedure: Two-stage exchange joint replacement surgery

Arms, Groups and Cohorts

  • Active Comparator: One-stage exchange
    • One surgery where the infected implants are removed and the hip or knee joint are ‘washed out’ before new joint replacement implants are re-implanted during the same surgical procedure.
  • Active Comparator: Two-stage exchange
    • Two surgeries; during the first surgery the infected implants are removed and a spacer is placed in the hip or knee joint in place of the implants. A second surgery to re-implant the hip or knee joint replacement implants is performed if and when the infection has cleared.

Clinical Trial Outcome Measures

Primary Measures

  • Recurrence of infection
    • Time Frame: 1 year following treatment
    • The primary outcome measured will be the recurrence of infection by the same organism or reinfection with a new organism as determined by the criteria using the International Consensus Meeting on PJI (1 year follow-up).

Secondary Measures

  • Health Related Quality of Health
    • Time Frame: 2 years following surgery
    • All patients will complete the Veteran’s Rand – 12 (VR-12) which is a general health measure. The VR-12 also yields a health utility measure that can be used to calculate quality-adjusted life years in an economic cost-utility analysis.
  • Patient-Reported Functional Outcomes
    • Time Frame: 2 years following surgery
    • Hip patients will complete the Hip disability and Osteoarthritis Outcome Score (HOOS), Junior which is a region-specific measure of pain and function of the hip.
  • Patient-Reported Functional Outcomes
    • Time Frame: 2 years following surgery
    • Knee patients will complete the Knee injury and Osteoarthritis Outcome Score (KOOS) Junior which is a region-specific measure of pain and function of the knee.

Participating in This Clinical Trial

Inclusion Criteria

  • Patients >18 years old – Patients who speak English and are willing to sign the consent form – Patients with chronic infection of a total knee or total hip arthroplasty, defined as: – A sinus communicating with the prosthesis – Two positive cultures obtained from the prosthesis – 3 of 5 criteria: (i) Elevated erythrocyte sedimentation rate (ESR) (>30mm/jr) and c-reactive protein (CRP) (>10mg/L) (ii) Elevated synovial leukocyte count (>3000 cells/µL) or change of ++ on leukocyte esterase strip (iii) Elevated synovial neutrophil percentage (>80%) (iv) One positive culture (v) Positive histological analysis of periprosthetic tissue (>5 neutrophils per high power field in 5 high power fields x400) – Patients with a previous irrigation and debridement for periprosthetic infection Exclusion Criteria:
