Method for realizing dynamic soft tissue balance judgment in total knee joint replacement

Abstract

The invention relates to the technical field of total knee joint replacement, and in particular relates to a method for realizing dynamic soft tissue balance judgment in total knee joint replacement.The method includes the following steps: obtaining a posture angle of a leg posture, and obtaining the following three postures: a knee joint extension and flexion angle alpha, a knee joint internal rotation and external rotation angle beta and a hip joint adduction and abduction angle gamma; performing standardization treatment on the alpha, beta and gamma data, and performing data normalization;and performing dynamic soft tissue balance judgment. In the method for realizing the dynamic soft tissue balance judgment in the total knee replacement surgery, a six-axis posture sensor is used to collect the intraoperative leg posture data, and a dynamic soft tissue balance judgment formula is constructed to perform soft tissue balance judgment to guide a doctor to make timely correction through a clinical technical means during operation, so that accurate recovery of a lower limb force line is realized; and the dynamic soft tissue balance judgment provided by the invention does not requiremuch time to learn, is easy to operate, and is inexpensive for mass production in the future.

Description

technical field [0001] The invention relates to the technical field of total knee replacement, in particular to a method for realizing dynamic soft tissue balance judgment in total knee replacement. Background technique [0002] The treatment of knee osteoarthritis is mainly divided into two categories: non-surgical treatment and surgical treatment. Non-surgical treatment can be divided into two categories: non-drug treatment and drug treatment. Non-drug treatment includes health education, functional exercise, physical therapy, acupuncture and massage therapy, etc.; drug treatment includes traditional Chinese medicine treatment, western medicine treatment and intra-articular injection of sodium hyaluronate with glucocorticoids, etc. The purpose of non-surgical treatment is to relieve pain, nourish articular cartilage, reduce inflammatory factors, and delay joint degeneration, while surgical treatment can correct the mechanical force line and morphological deformity of the ...

AI Technical Summary

Problems solved by technology

At present, the more mature soft tissue balance technology is mainly the computer navigation system and Verasense sensor system developed abroad. Although these systems have solved the problem of soft tissue balance judgment in the operation to a certain extent, the learning time is long and the operation is complicated, which prolongs the operation time. , increasing the risk of intraoperative infection

In addition, related instruments are expensive and not suitable for widespread use in hospitals
