Abstract

The invention discloses a total knee arthroplasty prosthesis model prediction method. The model comprises the steps that X-ray films of patient' knee joints before surgery and basic information of a patient are collected, wherein the X-ray films meet selection standards; the collected X-ray films and the basic information of the patient are preprocessed; and the pre-processed pictures and the basic information of the patient are used as features and input to a prosthesis model classifier trained based on a deep learning technology to acquire the use probability of each type of prosthesis in the surgery. According to the invention, the required prosthesis model can be efficiently and accurately predicted, and the detection accuracy rate can reach more than 84%; the accuracy rate reaches thesame level as the accuracy rate of preoperative prediction of experienced experts using CT and X-ray films; and the method provided by the invention only needs to use the X-ray films and the basic information of the patient, and has lower cost.

Description

technical field

[0001] The invention belongs to the field of artificial intelligence medical image processing, and in particular relates to the design of a prosthesis type prediction system for total knee arthroplasty and a prosthesis type prediction method based on the system. Background technique

[0002] Total knee arthroplasty (Total Knee Arthroplasty, TKA) is an effective method for the treatment of severe knee osteoinflammation and other diseases. While obtaining good clinical efficacy and reliable prosthesis survival rate, it also faces a series of postoperative complications. It affects the clinical curative effect of patients, and even requires revision surgery again, which increases the pain and medical burden of patients. According to different studies, the satisfaction rate of patients after total knee arthroplasty is only around 80%.

[0003] Accurate prosthesis matching is considered to be one of the important factors to reduce complications such as postoperat...
