The stress distribution of the cerclage wire. The maximum stress of the single cerclage wire is 1433 MPa, which is located at the lateral position of the posterior femur of the wire. The minimum stress is 41.2 MPa and located at the lateral position of the anterior femur. The maximum stress of the double wire was fixed at 147.8 MPa at the anterior medial position of the femur, and the minimum stress was 3.31 MPa at the posterior lateral position of the femur
