An acetabular cup removal device and method. The removal device can include a mounting ring attachable to an acetabular cup, a rotor rotatably coupled to the mounting ring and rotatable about a first axis, an arm pivotably coupled to the rotor and pivotable about a second axis orthogonal to the first axis, an oscillator assembly slidably disposed in a first slit of the arm, and a blade slidably disposed in a second slit of the arm. A rotation of the oscillator assembly causes an oscillation of the blade within the second slit. The removal method includes coupling the device to an acetabular cup, positioning the arm and blade at an initial location, oscillating the blade so as to perform a cut, repositioning the arm at a subsequent adjacent location, repeating the repositioning and oscillating steps until a 360° circumference is cut around the acetabular cup, and removing the acetabular cup.
