Abstract: An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.

Abstract: In an arthroendoscopical surgical method, a resection target area, and a freshening treatment area which becomes repair surfaces with bleeding, are identified, and a resection line and a freshening line are drawn on a tear site in a meniscus, which is emphasized by fluorescence with use of a fluorescent medicine under excitation light. Using an ultrasonic treatment tool and an arthroscope, the resection target area is resected by a probe which generates ultrasonic vibrations, based on the resection line and freshening line under visible-light illumination. Thus, an inclined resection surface is formed, and planar repair surfaces with bleeding are joined and repaired.

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.

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.
