Early postoperative rehabilitation training for supracondylar fracture of femur aids in accelerating healing with shorter recovery periods. Presently, clinical studies on early postoperative weight training are still in the nascent stage. The weight-bearing capacity at different healing stages typically depends on clinical experience, and there is a lack of standards to quantify the weight that is conducive to healing of fractures. In this paper, a three-dimensional (3D) geometric model of the femur is obtained using imaging data, a locking plate fixation model of a simple supracondylar fracture of the femur, considering the angle and spatial direction of the fracture surface, is established, the stress distribution and load transmission mechanism of the fracture fixation model in a single-leg standing posture are studied, and the weight-bearing capacity of a standing single leg at the early stage of fracture is given. This provides the basis for objective quantification of early postoperative weight-bearing capacity.
