Paper 104: A Simple Radiographic View with a Landmark of an Anterior Femoral Condyle for Determining Rotational Alignment of the Femoral Component in Total Knee Arthroplasty

Abstract

The precise rotational setting of the femoral component is important for adequate patella tracking and good ligament balance in total knee arthroplasty (TKA). The posterior condylar line (PC line) that connects the posterior condyle of the femur is widely used as a landmark for the cutting of the posterior condyle. An alternative landmark of the angle between the TEA and anterior trochlear line of the lateral and medial femoral condyles (trochlear line angle) for determining the rotational positioning of the femoral component should be considered.
