Our database of arthroplasties included all those implanted at our department, with preoperative and postoperative radiographic and clinical data, collected prospectively in a protocolized manner and with a systematized follow-up. The inclusion criteria described consecutive patients treated between 2001 and 2010 with knee arthrodesis due to an infected TKA. There were no exclusion criteria. We identified 29 cases and in all of them the arthrodesis was conducted through surgical revision in 2 stages, using the Endo-Model Link<span class="elsevierStyleSup">®</span> (Waldermar Link, Hamburg, Germany) intramedullary, modular nail.

The first stage consisted in prosthesis explantation, surgical cleaning and placement of a non-standardized cement spacer with gentamicin. Infection was treated with specific antibiotic therapy, intravenously for 1 month and orally up to 3 months. Infection was considered cured by normalization of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) values, along with at least 2 negative cultures obtained by joint puncture (culture and cell count) during the following 3 months. Thus, the interval for the second surgical stage was at least 6 months. Bone scintigraphy scans with marked leukocytes were only carried out in case of diagnostic doubt. The second stage consisted of reimplantation of the TKA if the extensor apparatus had not been damaged or an arthrodesis nail if it had. In cases where the infection recurred after reimplantation, a new surgical revision for arthrodesis was conducted.</p><p id="par0030" class="elsevierStylePara elsevierViewall">The arthrodesis was carried out in a second surgical stage, once the infection was considered cured. We took 5 intraoperative samples for culture. Subsequently, we started specific, intravenous antibiotic therapy according to the results of the previous cultures, during 2 weeks if the new cultures were negative. The arthrodesis nail consisted of 2 chromium-cobalt components of varying lengths, femoral and tibial, which were joined and screwed on each other at the level of the knee, providing a very robust connection with a fixed femorotibial angle of 5° in valgus in the frontal plane and 5° in flexion in the sagittal plane. The stems were introduced after drilling the medullary canals, in a retrograde direction in the femur and in an anterograde direction in the tibia, applying cement only in the metaphyseal portions. Given the technical difficulty of cementing the entire length of the nails, we ensured that an adequate cement filling of the metaphyseal portion was performed and at least 10<span class="elsevierStyleHsp" style=""></span>cm diaphyseally in each component. After attaching both components, the joint space was filled with a cement block with 80<span class="elsevierStyleHsp" style=""></span>mg of gentamicin (Cerafixgenta, Ceraver, France). Specific antibiotic and antithrombotic prophylaxis was applied, and load with a walking frame was permitted after the second postoperative day if pain allowed it.</p><p id="par0035" class="elsevierStylePara elsevierViewall">The series consisted of 25 females and 4 males, with a mean age of 74.6 years (range: 59–83 years) at the time of the arthrodesis.

The comorbidities at the time of the arthrodesis were varied, with 11 patients (37.9%) presenting type II diabetes and other associated pathologies, the most frequent being arterial hypertension, cardiopathy and chronic respiratory failure. The initial diagnosis in all cases had been of primary osteoarthritis. In 12 patients, the infection appeared after a primary TKA and in another 17 after an initially aseptic revision. In 12 patients, the infection was associated to a patellar tendon tear (5 cases), skin cover defect (1 case) and severe instability (1 case). All patients presented infection caused by a combination of germs, with some strain of <span class="elsevierStyleItalic">Staphylococcus</span> being identified in 21 patients (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>).</p><elsevierMultimedia ident="tbl0005"></elsevierMultimedia><p id="par0040" class="elsevierStylePara elsevierViewall">All patients had been prospectively examined, clinically and radiographically, at<a class="elsevierStyleCrossRefs" href="#bib0015"><span class="elsevierStyleSup">3,6,12</span></a> and at least until 36 months after the arthrodesis.

The scores of both questionnaires were calculated in a 0–100 scale, so that a higher value indicated a better condition of the patient.

In the last assessment, 4 patients reported pain in the knee upon walking, with 3 requiring a walking frame and 1 requiring 2 crutches. One patient reported occasional pain in the thigh and another pain in the lumbar region.

The eroded nail was replaced by a longer nail and the patient reported no pain and no need for walking aids. Another patient presented a peri-implant fracture at the level of the proximal end of the nail, due to a fall down a staircase after 3 years, requiring revision and a longer nail, as well as internal femoral fixation with a femoral plate.
