| 1. A method of performing a surgical procedure on a knee comprising the following successive steps of:
Incising an anterior zone and one of an external or internal zone of the knee to form an incision;
holding back edges of the incision to reveal at least part of a corresponding external or internal femoral condyle of the
knee;
introducing a pointed distal end of a patellar retractor into a femoral intercondylar space of the knee through the incision;
abutting the pointed distal end on a wall of the revealed condyle facing the femoral intercondylar space; and
pushing part of a quadriceps muscle tendon containing the patella in a medial-lateral direction towards the unrevealed condyle
to dislocate a patella of the knee using the patellar retractor as a lever.
