Abstract
This surgical apparatus comprises, on the one hand, means for spatial marking-out of the kneecap and femur of a patient to be operated on, and, on the other hand, means for simultaneous and relative representation of this kneecap provided virtually with a patellar implant of the prosthesis, and of this femur provided virtually with a femoral implant of the prosthesis, in a sagittal plane passing both through the kneecap and through the trochlea of the aforementioned femoral implant. Using this apparatus, the surgeon can easily and quickly check the antero-posterior size of the prosthesis in order to reduce the risks of subsequent dislocations of the kneecap fitted with the prosthesis.
