Detailed Product Description

The design is in conformity with anatomical size of the knee joint, increasing the covered surface of the bone by the prosthesis
The Deluxe series knee prosthesis is designed on the basis of the data obtained from the accurate analysis of anatomical information from 105 patients, concerning the shape and size of their distal end of femur, proximal end of tibia and patella. After the study of the geometrical data of the articulating surfaces of the distal end of femur, proximal end of tibia and patella, we determined the ratio between the inside and outside diameter and the ratio between the anteroposterior diameters of the distal end of femur and the proximal end of tibia. As a result, the covered area of the bone is increased and the bone absorption, as well as the prosthesis sinking, due to the uneven distribution of local stress on the cutting surface, is avoided. The uneven distribution of local stress is the result of poor covered area of the bone by the prosthesis.
