Abstract

The present application discloses a method of producing a knee replacement implant, an implant for knee replacement formed by using the method, and a knee replacement implant. The method includes: defining a hip center, a knee center, an ankle center and a posterior femoral condylar axis of a lower limb; generating femoral geometric parameters and tibial geometric parameters, the femoral geometric parameters and the tibial geometric parameters being measured in relation to the hip center, the knee center, the ankle center and the posterior femoral condylar axis; collecting anthropometric data from a defined population using the femoral geometric parameters and the tibial geometric parameters; and creating a femoral component and/or a tibial component using the collected anthropometric data.
