Abstract:
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.
