One Stage Versus Two Stage For Periprosthetic Hip And Knee Infection

Surgical Site Infection Clinical Trial

Official title: One Stage Versus Two Stage For Periprosthetic Hip And Knee Infection

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to compare the outcomes of two different treatment options commonly used to manage periprosthetic joint infection (PJI), an infection around the artificial knee or hip.

Clinical Trial 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. ;
