Clinical Evaluation of Arthrodesis with External Fixation of the Knee

Abstract

The outcome of arthrodesis of the knee was evaluated, including investigation of postoperative problems in activities of daily living (ADL). Eight knees in eight patients were treated by arthrodesis with external fixation. All patients achieved solid fusion, at an average of 4.7 months after surgery. Fusions were aligned in 12.1±6.5 degrees of flexion and in 5.4±2.1 degrees of valgus angulation. The average shortening in all eight patients was 3.2 centimeters. Analysis of ADL revealed a high percentage of patients who had difficulty using the toilet or bathing themselves postoperatively. In all patients, however, pain was relieved completely and the fused knee provided adequate support to the loads imposed. All arthrodesed knees were completely functional and all patients were highly satisfied with the results of the operation.
