Abstract
Total knee arthroplasty is an effective method for treating severe knee joint diseases, but the changes in patellar height and psychological state of patients after surgery are still of great concern. Select a group of patients who have undergone total knee replacement surgery as the research subjects, use radioactive CT imaging to examine the knee joints of the patients, and input them into the computer system for analysis. Based on the position, shape, and surrounding structure of the patella in the images, process them to obtain the specific value of patellar height. Radioactive CT imaging examination showed that there was a significant change in patellar height in patients after total knee arthroplasty, and the degree of change was related to the preoperative knee joint condition. The results showed that there was a significant change in patellar height in patients after total knee arthroplasty. The results of the radioactive CT imaging examination showed a significant increase in patellar height after surgery, with a significant improvement compared to before. The psychological evaluation results of the patient showed that after surgery, the patient's psychological condition significantly improved, and the levels of anxiety and depression were significantly reduced.
