The invention provides a hip joint torque measurement system, comprising a fixing device suitable for being fixed on a limb connected with the hip joint to be measured, a strain device fixedly connected with the fixing device, and the strain device is exerted force and passed through the When the fixation device rotates the limb, and thus the femur covered by the limb around the axis of the femur, a uniform strain can be generated, and a measuring device for determining the amount of strain of the strain device. The hip joint torque measurement system of the present invention can measure the moment of the patient's hip joint during the operation, verify the necessity of soft tissue repair of the hip joint, and determine how to perform targeted and effective repair of the patient's soft tissue according to the measurement results , reconstruct the soft tissue balance of the hip joint after surgery, and increase the stability of the hip joint, thereby improving the curative effect of total hip replacement surgery and significantly reducing the postoperative dislocation rate.
