ABSTRACT:
The tibula, fibia and femur of a whole poultry leg are removed by making a lengthwise cut along the inside of the leg, along the rear of the tibula and femur, then making a lateral cut part way through the knee joint, then supporting the thigh and bending the knee joint to expose the end of the femur, then plunging a cup-type knife over the exposed end of the femur and through the knee joint, to sever the ligaments in the joint and separate the exposed end of the femur from the thigh flesh, then moving the knife laterally of the femur axis to withdraw the femur through the lengthwise cut in the thigh, and then removing the tibula and fibia through the lengthwise cut in the drumstick. An apparatus for automatically performing a portion of the method is also disclosed.
