The present invention relates to a testing tool for checking mobility of a tibia prosthesis which is joined with a tibia before transplanting the tibia prosthesis used for total nee arthroplasty. More specifically, the present invention relates to a tibia prosthesis testing tool for total knee arthroplasty including: a plate testing unit joined with a tibia; and an insert testing unit which is detachably joined with an upper side of the plate testing unit. The plate testing unit includes a fixation unit which is formed on one side, is joined with a joining unit when the plate testing unit is joined with the insert testing unit, and prevents the plate testing unit from being detached from the insert testing unit. The insert testing unit includes the joining unit which is formed on one side and detachably joins the plate testing unit and the insert testing unit by pressing the fixation unit. The insert testing unit can be replaced in an easy manner while the plate testing unit is tightly joined with the insert testing unit. Therefore, the tibia prosthesis testing tool for total knee arthroplasty enables a user to accurately test mobility of a knee joint and to properly select a tibia prosthesis, and has enhanced convenience of use. |
