Femoral Radiographic Landmarks for Popliteus Tendon Reconstruction and Repair: A New Method of Reference
2014
Background:Although the popliteus muscle-tendon complex is one of the most important structures in controlling posterolateral rotatory stability of the knee, not much literature has been reported concerning the use of femoral radiographic landmarks of the popliteus tendon in repair and reconstruction.Hypothesis:By using standardized radiographic techniques, the femoral insertion of the popliteus tendon could be more precisely determined by the Blumensaat line than by the extension line of the posterior cortex.Study Design:Descriptive laboratory study.Methods:Ten fresh-frozen human knees were dissected, and the popliteus tendon was exposed. After identification of the femoral insertion site of the popliteus tendon, the insertion’s center was indicated with a radiographic marker. True lateral radiographs of the distal femur were taken, and the digital radiographic images were analyzed by 2 independent observers.Results:The femoral insertion site of the popliteus tendon was found to be a mean 47.5% ± 5.2% ac...
