[Arthrodesis without bone fusion with an intramedullary modular nail for revision of infected total knee arthroplasty].

OBJECTIVE To evaluate the outcome of knee fixation without bone fusion using an intramedullary modular nail and interposed cement. MATERIAL AND METHODS Retrospective study of 29 infected total knee arthroplasties with prospective data collection and a mean follow-up of 4.2 years (3-5). RESULTS Complications included 2 recurrent infections, 1 peri-implant fracture, and 1 cortical erosion due to the tip of the femoral component. All of these were revised with successful results. The mean limb length discrepancy was 0.8 cm, with 24<1cm. Twenty-five patients reported no pain. The mean WOMAC-pain was 86.9, WOMAC-function 56.4, SF12-physical 45.1, and SF12-mental 53.7. Four patients needed a walking frame, and only two were dependent for daily activities. CONCLUSIONS The Endo-Model Link nail is an effective method for knee fixation that restores the anatomical alignment of the limb with adequate leg length.
