| description | 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 revision procedure with the newly
developed CPLS between June 2006 and June 2011. Based on the microorganism involved,
patients were grouped into either easy to treat (ETT) or difficult to treat (DTT) and treated accordingly.
Range of motion (ROM) and the knee society score (KSS) were utilized for functional
assessment. Results. Mean duration of the CPLS implant in the DTT
group was 3.6 months (range 3–5 months) and in the ETT group 1.3 months
(range 0.7–2.5 months). Reinfection rates of the final prosthesis were
9.6% in the ETT and 8.3% in the DTT group with no significant difference between both groups regarding ROM or KSS (, , resp.). Conclusion. The
results show that ETT patients do not necessitate the same treatment protocol as
DTT patients to achieve the same goal, emphasizing the need to differentiate between
therapeutic regimes. We also highlight the feasibility of CLPS in two-stage protocols. |
