Knee-joint discoid meniscus surgery simulation method

Abstract

The invention discloses a knee-joint discoid meniscus surgery simulation method. The method comprises the steps that the knee joint of a patient suffering from discoid meniscus is subjected to CT and MRI scanning; CT and MRI data is processed, and a three-dimensional skeleton model and a three-dimensional cartilage, ligament and meniscus model are obtained; the three-dimensional skeleton model and a three-dimensional cartilage, ligament and meniscus model are subjected to registration, and coordinate positions of skeletons, cartilage, ligaments and menisci are generated; the three-dimensional skeleton model and the three-dimensional cartilage, ligament and meniscus model are subjected to surface reconstruction, and skeleton, cartilage, ligament and meniscus NURBS surface models are obtained, the skeleton, cartilage, ligament and meniscus NURBS surface models are assembled according to the anatomical structure, and a knee-joint entity model is generated; the diseased region in the discoid meniscus is excised on the knee-joint entity model so as to simulate trimming surgery. According to the technical scheme, the surgery process can be simulated for the diseased region of the knee joint of the patient, and doctor-patient communication is enhanced.

Description

technical field [0001] The invention relates to the technical field of computer three-dimensional simulation, in particular to a method for simulating a discoid meniscus of the knee joint. Background technique [0002] In medicine, normal human knee joints are often used for three-dimensional modeling, and various researches are carried out on the established three-dimensional knee joint models. A discoid meniscus is a rare meniscal deformity in which there are more lateral discoid menisci than medial discoid menisci. It is reported that the incidence of lateral discoid meniscus is 26% in Japanese and Korean patients, but less than 1% in patients from other countries, and the incidence of medial discoid meniscus is 0% to 0.3%. [0003] At present, there is no consensus on the best surgical method for discoid meniscus surgery clinically, and it is difficult to pre-evaluate the postoperative effect, and there is currently no simple and intuitive method to simulate discoid men...
