Two-stage exchange of infected knee arthroplasty with an prosthesis-like interim cement spacer.

چکیده
Two-stage revision in infected knee arthroplasty is standard practice. One problem during the interim period is soft tissue fibrosis. Attempts have been made to preserve leg length and ligament length by introducing spacers, usually made out of antibiotic-loaded bone cement. We present a new interim prosthesis, which is made intra-operatively out of polymethylmethacrylate (PMMA). Antibiotic-loaded cement provides a therapeutic level of antibiotics in the periarticular soft tissue. We report the results in ten patients, who were treated with this prosthesis-like spacer and were prospectively studied. After an average follow-up of 13.5 months, there was no recurrent infection.

The PROSTALAC functional spacer in two-stage revision for infected knee replacements. Prosthesis of antibiotic-loaded acrylic cement.
The PROSTALAC functional spacer is made of antibiotic-loaded acrylic cement but has a small metal-on-polythene articular surface. We have used it as an interim spacer in two-stage exchange arthroplasty for infected total knee replacement. PROSTALAC allows continuous rehabilitation between stages as it maintains good alignment and stability of the knee and a reasonable range of movement. It also...
متن کاملSonication of antibiotic-loaded cement spacers in a two-stage revision protocol for infected joint arthroplasty
BACKGROUND Culturing of the sonication fluid of removed implants has proven to be more sensitive than conventional periprosthetic tissue culture for the microbiological diagnosis of prosthetic joint infection. Since bacteria surviving on antibiotic-loaded cement spacers used in a two-stage exchange protocol for infected arthroplasties may cause the persistence of infection, in this study we ask...

BACKGROUND Periprosthetic infections remain a devastating problem in the field of joint arthroplasty. In the following study, the results of a two-stage treatment protocol for chronic periprosthetic infections using an intraoperatively molded cement prosthesis-like spacer (CPLS) are presented. METHODS Seventy-five patients with chronically infected knee prosthesis received a two-stage revisio...
متن کاملDiagnosis and Management of Infected Total Knee Arthroplasty§
Infection following total knee arthroplasty can be difficult to diagnose and treat. Diagnosis is multifactorial and relies on the clinical picture, radiographs, bone scans, serologic tests, synovial fluid examination, intra-operative culture and histology. Newer techniques including ultrasonication and molecular diagnostic studies are playing an expanded role. Two-stage exchange arthroplasty wi...
