Abstract

The invention provides an intraoperative planning adjustment method, device and equipment for total knee replacement and a computer readable medium. The method comprises the following steps: importingpreoperative planning data; performing image registration on preoperative planning images and the surface contour of a knee joint of an operation object; acquiring knee joint dynamic spacing force line data under continuous flexion and extension angle; visually displaying a dynamic spacing force line data graph; and adjusting prosthesis planning according to the visual display of the dynamic spacing force line data. By calculating information such as the joint space and the force line angle under the continuous flexion and extension angle of the lower limb in the operation, the method provides a comprehensive adjustment information source in the operation for an operator, and therefore a better operation planning scheme is obtained.

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...
