With the increase of age, the prevalence of osteoarthritis increases rapidly, which is the main cause of joint pain and disability in the elderly. Under the simultaneous action of various external and internal factors, firstly, hyaline cartilage in the joint has cell degeneration, extracellular matrix degradation or variation, then inflammatory factors can be released and adhesion occurs, making the joint inflammatory response, and finally the articular cartilage gradually fibrosis, thus showing the symptoms of joint pain and loss of function. Therefore, this paper starts from the point of view of the relationship between articular cartilage and knee osteoarthritis and the influence of Taijiquan on articular cartilage. Based on this background, the research content of this paper is based on the ultrastructural analysis of articular cartilage in the patients with knee osteoarthritis after exercise with microscope. Through the simulation analysis of Japanese white rabbits and knee osteoarthritis patients, the results show that 1 At 6 weeks, compared with 8 weeks, the pathological changes of cartilage tissue were further aggravated, the cartilage layer became thinner, the cartilage membrane was damaged, the number of chondrocytes was significantly reduced, deformation and necrosis were observed. There was no significant difference in the activity of complex enzyme between OA patients and normal people, but it was lower than that of normal people.
