The influence of femoral component positioning on patellar tracking is critical. The various possibilities of modifying the position of the femoral component relative to the distal femoral epiphysis are analyzed, and the ideal positioning in the medio-lateral, antero-posterior, and proximal-distal directions is described. Special emphasis is placed on the rotational positioning of the femoral component.
