Das Ziel der vorgestellten retrospektiven Arbeit ist die Vorstellung der Erfolgsrate von Re-Implantationen nach periprothetischen K-TEP-Infektionen bei zweizeitigen Eingriffen. Zwingende Voraussetzung für die Re-Implantation ist die Infektsanierung. In den meisten Fällen bedeutet dies den Wechsel der Endoprothese, wobei einzeitige und zweizeitige Verfahren unterschieden werden. From our point of view, the optimal timing for re-implantation depends on various specific factors and therefore it should be defined individually.ĭie periprothetische Infektion nach Kniegelenksendoprothesen (K-TEP) ist eine der schwerwiegenden Komplikationen, die mit einem möglichst effektiven Konzept therapeutisch verfolgt werden muss. Our data point out to the fact that a longer time interval between explantation and re-implantation reduces the rate of reinfection. In particular, no optimal timing can be stated concerning re-implantation. No uniform strategy of treatment exists after peri-prosthetic infections. Mobile spacers proved better outcome than temporary arthrodesis with intramedullary fixation. Nevertheless, we noticed no essential differences in outcome with regard to the number of surgeries carried out prior to re-implantation. Those patients with uncomplicated course were operated on (re-implantation) after an average of 6.79 months. Patients who developed reinfections were operated on (re-implantation) after an average of 4.47 months. The number of the reinfections declined with increasing time interval between explantation and re-implantation. We reported 31.4% (11) reinfections following re-implantation surgeries. We particularly evaluated the microbial spectrum, the interval between explantation and re-implantation, the number of surgeries that were necessary prior to re-implantation as well as the postoperative course. The average age at re-implantation time was 72.2 years (ranging from 54 to 85 years). The patient's group comprised of 53% (18) males and 47% (16) females. 35 re-implantations were carried out following explantation of total knee and implantation of cemented spacer. It further considers drawing conclusions concerning the optimal timing of re-implantation.Ī total of 34 patients have been enclosed in this study from September 2005 to December 2013. This retrospective work presents an assessment of the success rate after a two-setting revision arthroplasty of the knee following periprosthetic infection. Healing of infection is the conditio sine qua non for re-implantation. In most cases this means revision arthroplasty, in which one-setting and two-setting procedures are distinguished. Infection after total knee replacement (TKR) is one of the serious complications which must be pursued with a very effective therapeutic concept.
