PRIMARY outcome

Timeframe: 2 weeks

Population: The rotational angle between the femur and tibia was collected by postoperative CT and asssessed between the transepicondylar angle in the femur and the vertical line of the AP axis of the tibia(the line between the insertion of the PCL and the medial 1/3 point of the tibial tuberosity).
