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.
