Method for revision arthroplasty

A method for revision arthroplasty, comprising:

• detaching an existing acetabulum component of an artificial joint from an acetabulum, the existing acetabulum component being fixed to the acetabulum by cement, and the artificial joint being composed of the existing acetabulum component and a femur component;
• breaking and removing the cement and bone remaining in the acetabulum from which the existing acetabulum component was detached, by transmitting ultrasonic vibration to a treating section provided at a probe distal end of an ultrasonic treatment device when the treating section is brought into contact with the cement and the bone, and regenerating the acetabulum for a new acetabulum component;
• applying cement to the regenerated acetabulum;
• and
• attaching and fixing the new acetabulum component in the regenerated acetabulum.

A method for revision arthroplasty, comprising:

• detaching, from an artificial joint composed of an existing femur component and existing acetabulum component fixed by cement, the femur component;
• a femur component revision arthroplasty including:
• detaching the existing femur component of the artificial joint from a femur;
• breaking and removing the cement and bone remaining in an attaching of the femur from which the existing femur component was detached, by transmitting ultrasonic vibration to a treating section provided at a probe distal end of an ultrasonic treatment device when the treating section is brought into contact with the cement and the bone, and regenerating an attaching hole of the femur for a new femur component;
• and
• applying cement in the regenerated attaching hole of the femur;
• and
• attaching and fixing the new femur component in the regenerated attaching hole of the femur;
• and
• an acetabulum component revision arthroplasty including:
• detaching the existing acetabulum component of the artificial joint from an acetabulum,
• breaking and removing the cement and the bone remaining in the acetabulum from which the existing acetabulum component was detached, by the transmitting of the ultrasonic vibration to the treating section when the treating section is brought into contact with the cement and the bone, and regenerating the acetabulum for a new acetabulum component;
• applying cement to the regenerated acetabulum;
• and
• attaching and fixing the new acetabulum component in the regenerated acetabulum,
• wherein the femur component revision arthroplasty and the acetabulum component revision arthroplasty are performed in any order;
• and
• assembling and coupling the new femur component and the new acetabulum component.
