Abstract

BackgroundDespite improvements in surgical technique, the number of infections after total knee arthroplasty continues to rise. According to bibliographic reviews, the two-stage exchange procedure has obtained higher percentages of cure than that performed in a single stage. The purpose of this paper was to show our technique for preparing the static spacer, the results and the range of motion achieved with two-stage revision of infected total knee arthroplasty using those spacers. Espaciadores estáticos de cemento con antibiótico en la infección protésica de rodilla Técnica de elaboración y movilidad posoperatoria MethodsWe performed 153 total knee arthroplasty revisions between 1997 and 2010, 33 (21%) of them due to a prosthetic chronic infection, treated with a two-stage procedure with cement static spacer with antibiotic. We evaluated 33 total knee arthroplasties in 32 patients, with an average age of 69 years and an average postoperative follow-up of 3.5 years.ResultsHealing was achieved in 30 (91%) of the 33 knees. Twenty-eight knees were successfully reimplanted, two with healing infection were not reimplanted for different reasons and 3 had persistent infection. The 28 reimplanted knees evolved favorably, achieving a range of motion of 90º in an average of 3 months after surgery.ConclusionsThe static knee spacer achieved a similar healing rate to that obtained with articulated spacers. The advantage of static spacers is its easy manufacture and placement, giving greater stability and an acceptable range of motion.
