Preparation method of individual artificial knee joint based on biomechanics

Abstract

The invention provides a preparation method of individual artificial knee joint based on biomechanics, for solving the problem that the matching degree between the existing artificial joint and the human body joint is poor, so that the stress distribution is unreasonable, and the service life is short. The preparation method comprises the following steps: manufacturing a physiological data standard template of the normal human body; manufacturing a physiological data standard template of a patient; according to the physiological data standard template of the patient, searching for data matched with the physiological data standard template of the patient, wherein the data is taken as a contrast; searching for muscle with malformed stressing in the lower limb muscle of the patient in the gait period; calculating to obtain kinematic data in the gait period; comparing the kinematic data obtained after substitution with the contrast, finding out the differences, modifying the design of the artificial knee till the obtained kinematic data is matched with the kinematic data of the contrast, thus obtaining the individual artificial knee joint conforming to the mechanics characteristics of the biomechanics. According to the preparation method, while the performances of the artificial knee are optimized, the service life of the artificial knee in the body of the patient is effectively prolonged.

Description

Technical field [0001] The invention relates to a preparation method of an artificial joint, in particular to a preparation method of a personalized artificial knee joint based on biomechanics. Background technique [0002] At present, my country has become one of the countries with the largest elderly population in the world, and the incidence of senile diseases, including knee osteoarthropathy and hip osteoarthropathy, is increasing with age. Bone and joint diseases have seriously affected the quality of life of the elderly, and even threatened their lives. At present, with the development of the economy and the improvement of living standards, osteoarthropathy has begun to tend to be younger. In the future, more and more people will suffer from osteoarthropathy. [0003] Artificial joint replacement is most suitable for people with joint dysfunction caused by osteoarthritis. Although joint replacement has become a more common method to solve osteoarthritis, and there is a high...
