Provided is a measurement instrument for joint surgery with which it is possible to move a first bone and a second bone, which are connected by soft tissue in a joint, relative to each other in a direction other than that in which the bones move away from each other, and measure the stability of the connection state between the bones. A housing (11) is provided so that the housing (11) can be fixed to the first bone (101). A slider (12) is provided so as to be slidable on the housing (11), and provided so that the slider (12) can be brought into contact with the second bone (102). A position display (13a) displays the position of the slider (12) relative to the housing (11). In the measurement instrument (1) for joint surgery, the slider (12) moves in a sliding manner relative to the housing (11), whereby the second bone (102) is moved relative to the first bone (101) along a joint surface. The stability of the connection state between the first bone (101) and the second bone (102) is measured on the basis of the position of the slider (12) relative to the housing (11) displayed on the position display (13a). |
