Problems solved by technology

Because implants and prostheses are not available in many sizes and anthropometric features of knee data from many races are not incorporated into the implant and prosthesis design process, many patients of multiple races are reported Mismatch with available implants and prostheses
Undersizing of implants and prostheses will lead to subsidence of implants and prostheses, while protruding parts will cause soft tissue wear and eventual failure of the procedure

Embodiment Construction

[0025] Hereinafter, the present application will be described in detail with reference to the accompanying drawings.

[0026] The knee replacement implants described herein may include implants and prostheses for knee replacement. This implant can be used to internally fix a fractured or damaged broken part. This prosthesis can be used to replace all or part of a bone.

[0027] figure 1 It is a flowchart illustrating a method of manufacturing a knee replacement implant according to one embodiment of the present application. Such as figure 1 As shown, the method 1000 includes steps S1100-S1400.

[0028] In step S1100, the center of the hip joint, the center of the knee joint, the center of the ankle joint and the axis of the posterior femoral condyle of the lower limb are defined. In this embodiment, the hip joint center, knee joint center, ankle joint center and posterior femoral condyle axis of the lower limb can be defined in medical image processing software (such as M...

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 geometricparameters 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 datafrom 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.

Description

technical field [0001] The present application relates to methods for manufacturing knee replacement implants and knee replacement implants formed using the methods. Background technique [0002] Total knee replacement is a common orthopedic procedure for patients whose limbs have been severely damaged due to arthritis or injury. During the procedure, the fractured or damaged broken part is fixed internally by an appropriate implant or replaced by the most suitable prosthesis available. [0003] Implants and prostheses available in the prior art are designed for a small number of ethnic groups. However, numerous studies have shown that the human skeleton is different among different ethnic groups. Because implants and prostheses are not available in many sizes and anthropometric characterization of knee data from many races is not incorporated into the implant and prosthesis design process, many patients of multiple races are reported Mismatch with available implants and ...
