Abstract

The present application provides an intraoperative planning adjustment method, device, equipment and computer readable medium for total knee replacement. The method includes: importing preoperative planning data; image registration of the preoperative planning image and the surface contour of the knee joint of the surgical object; acquiring dynamic distance force line data of the knee joint under continuous flexion and extension angles; visually displaying the dynamic distance force line Data map; adjust the prosthesis planning according to the visual display of the dynamic spacing force line data. By calculating the joint distance, force line angle and other information under the continuous flexion and extension angle of the lower limbs during the operation, it provides the operator with a comprehensive source of intraoperative adjustment information, so as to obtain a better surgical planning plan.

Description

technical field [0001] The present application belongs to the technical field of joint replacement, and in particular relates to a method, device, electronic device and computer-readable medium for intraoperative planning adjustment of total knee replacement. Background technique [0002] Total knee arthroplasty (Total Knee Arthroplasty, hereinafter referred to as TKA) is a new technology for the treatment of knee joint diseases. By replacing the articulation surface of the knee joint with prosthetic components, it can very effectively eradicate severe knee joint pain and greatly Improve the quality of life of surgical subjects. Factors affecting the effect of joint replacement include accurate osteotomy in three-dimensional space, the balance and stability of soft tissues such as ligaments, and the position and angle of prosthesis placement. Total knee replacement has particularly strict requirements on these factors. [0003] The application of computer-aided system in to...
