Surgical equipment specific to a patient for the preparation of the knee of the patient.

摘要

This instrumentation surgery (1), designed to be "on " for a given patient, comprises a block femoral specific to the patient (10), which defines a surface area (10a) of the fixed support on the femur (f) of the patient, shaped specifically adjusted to the femur, and a tibial specific to the patient (20), which defines a surface area (20a) of the fixed support on the tibia (t) of the patient, shaped specifically adjusted to the tibia. According to the invention, the equipment further comprises means (30) for measuring the relative positioning between the femur and the tibia, these measuring means include first and second portions (31, 32), which are carried respectively by the block femoral and tibial by the block, and which are adapted for, whereas the blocks femoral and tibial are respectively supported securely on the femur and the tibia by their bearing surface cooperating with one another so as to be measured at least a geometrical characteristic, in particular, the angle hka, the relative positioning between the blocks femoral and tibial without acting on this characteristic.
