Abstract

A knee joint surgical treatment under an arthroscope includes: contacting a treating portion of an ultrasonic device with an end region to which an ACL or a PCL of a tibia adheres and with a start region to which the ACL or the PCL of a femur adheres, excising the tibia and a remaining ligament of the ACL, or the tibia and a remaining ligament of the PCL, excising the femur and a remaining ligament of the ACL, or the femur and a remaining ligament of the PCL by ultrasonically vibrating the treating portion, thereby exposing footprints of the tibia and the femur; and forming tunnels between the footprint of the tibia and a medial side of a rough surface of the tibia and between the footprint of the femur and an lateral surface of a lateral condyle of the femur.

First claim

What is claimed is:

1. A knee joint surgical treatment which is to be performed under an arthroscope, the surgical treatment comprising:
inserting the arthroscope and a treating portion of an ultrasonic device into a knee joint;
bringing the treating portion of the ultrasonic device into contact with an end region to which an anterior cruciate ligament or a posterior cruciate ligament of a tibia adheres, and excising the tibia and a remaining ligament of the anterior cruciate ligament, or the tibia and a remaining ligament of the posterior cruciate ligament by ultrasonically vibrating the treating portion, thereby exposing a footprint region of the tibia;
bringing the treating portion of the ultrasonic device into contact with a start region to which the anterior cruciate ligament or the posterior cruciate ligament of a femur adheres, and excising the femur and a remaining ligament of the anterior cruciate ligament, or the femur and a remaining ligament of the posterior cruciate ligament by ultrasonically vibrating the treating portion, thereby exposing a footprint region of the femur;
forming a tunnel between the footprint region of the tibia and a medial side of a rough surface of the tibia;
forming a tunnel between the footprint region of the femur and an lateral surface of a lateral condyle of the femur; and
respectively fixing a graft prepared in advance to the tunnels formed in the femur and the tibia.

2. The surgical treatment according to claim 1 , wherein the exposing of the footprint region of the tibia comprises using the same ultrasonic device as that used in exposing the footprint region of the femur.

3. The surgical treatment according to claim 1 , comprising ultrasonically vibrating the treating portion of the ultrasonic device to treat a damaged region of a meniscus, before exposing the footprint regions of the tibia and the femur.

4. The surgical treatment according to claim 1 , comprising ultrasonically vibrating the treating portion of the ultrasonic device to remove an inflamed region of a synovial membrane in an articular capsule, before exposing the footprint regions of the tibia and the femur.

5. The surgical treatment according to claim 1 , comprising ultrasonically vibrating the treating portion of the ultrasonic device to remove a damaged region of a cartilage, before exposing the footprint regions of the tibia and the femur.
