Abstract

Provided are an intraoperative planning adjustment method, apparatus and device for TKA (Total Knee Arthroplasty) and a computer-readable medium. The method comprises: importing preoperative planning data; performing image registration on preoperative planning images and the surface contour of a knee joint of a surgical object; acquiring the dynamic spacing force line data of the knee joint at a continuous flexion-extension angle; visually displaying the 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 gap and the force line angle of the lower limb at the continuous flexion-extension angle in the operation, the method provides a comprehensive adjustment information source in the operation for a surgeon, and therefore a better operation planning is obtained.
