Abstract

A surgical treatment of a ligament of a knee joint under an arthroscope, includes: forming concave holes from the region of the tibia to which the ligament adheres toward an inner side of a rough surface of the tibia and from the region of the femur to which the ligament adheres toward an outer surface of a lateral condyle of the femur by ultrasonically vibrating the treating portion; forming tunnels between the concave hole of the tibia and the medial side of the rough surface of the tibia using the concave hole of the tibia and between the concave hole of the femur and the lateral surface of the lateral condyle of the femur using the concave hole of the femur.

First claim

What is claimed is:

1. A surgical treatment of an anterior cruciate ligament or a posterior cruciate ligament of a knee joint which is to be performed under an arthroscope, the surgical treatment comprising:
inserting the arthroscope and a treating portion of an ultrasonic device into the knee joint;
bringing the treating portion of the ultrasonic device into contact with a region of a tibia to which the ligament adheres, and forming a concave hole from the region of the tibia to which the ligament adheres toward an inner side of a rough surface of the tibia by ultrasonically vibrating the treating portion;
bringing the treating portion of the ultrasonic device into contact with a region of a femur to which the ligament adheres, and forming a concave hole from the region of the femur to which the ligament adheres toward an outer surface of a lateral condyle of the femur by ultrasonically vibrating the treating portion;
forming a tunnel between the concave hole of the tibia and the medial side of the rough surface of the tibia using the concave hole of the tibia as a supporting point;
forming a tunnel between the concave hole of the femur and the lateral surface of the lateral condyle of the femur using the concave hole of the femur as a supporting point;
fixing one end side of a graft prepared in advance to the lateral surface of the lateral condyle of the femur; and
fixing the other end side of the graft to the medial side of the rough surface of the tibia.

2. The surgical treatment according to claim 1 , comprising:
disposing one end of a main body of an instrument that guides a drill to form the tunnel in the concave hole of the femur, and
disposing one end of a guiding tube of the instrument which guides the drill toward the concave hole in the lateral surface of the lateral condyle of the femur through skin of a lateral side of the knee joint.

3. The surgical treatment according to claim 1 , comprising:
disposing one end of a main body of an instrument that guides a drill to form the tunnel in the concave hole of the tibia, and
disposing one end of a guiding tube of the instrument which guides the drill toward the concave hole in the rough surface of the tibia through skin of an outer side of the knee joint.
