KNEE JOINT SURGICAL TREATMENT

摘要

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.

主权项

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.
