Abstract

The invention provides a total knee replacement post-operation revision pre-operation planning method based on deep learning, and the method comprises the steps: inputting a pre-operation knee joint image into a deep learning model, and obtaining a pre-operation knee joint prosthesis image and a pre-operation joint line image; wherein the preoperative joint line image is a preoperative knee joint image marked with a knee joint line; and determining the specification, model and position of a first knee joint prosthesis based on the preoperative knee joint prosthesis image and the preoperative joint line image. According to the total knee replacement postoperative revision preoperative planning method based on deep learning, the position, specification and model of the first knee joint prosthesis can be accurately and rapidly recognized, the measurement time is short, the accuracy is high, the operation time is shortened, and more accurate preoperative data support is provided for knee joint revision.

Description

technical field [0001] The present invention relates to the technical field of knee arthroplasty, in particular to a method and system for preoperative planning of total knee arthroplasty based on deep learning. Background technique [0002] After knee replacement, the patient's knee joint may experience symptoms such as looseness, infection, pain, and limited flexion and extension function, which may indicate that the patella track is not correct, and the knee joint prosthesis needs to be revised again. That is, the knee prosthesis is removed and a new knee prosthesis is reinstalled. Due to the impact of primary knee arthroplasty, the normal anatomical structure of the knee joint is destroyed, and there is a lot of bone loss. In revision knee surgery, it is difficult to determine the position and size of the knee prosthesis, resulting in longer operation time and higher risk of surgery and complications. Contents of the invention [0003] The present invention provides ...
