A method for providing a tool system, the tool system being suitable for removing prosthetic cement from a bone of a patient undergoing a joint prosthesis replacement operation, the method comprising the steps of: scanning the patient in the area of the joint prosthesis so as to obtain at least one profile of a line of intersection of a prosthetic cement/bone interface at its intersection with a generally longitudinally pre-selected plane; and providing a cutting tool, the cutting tool being suitable for forming a running cut substantially completely through the prosthetic cement along the line of intersection; wherein the cutting tool comprises: an elongated stem having dimensions to be able to be inserted into a prosthetic cavity located in said prosthetic cement, at least substantially to the bottom end thereof; a cutting element arranged on said stem and arranged to cut the prosthetic cement at one outer end of said stem; a grip arranged on the other outer end of said stem for engagement of the cutting tool by an operator; and wherein the stem of the cutting tool comprises two laterally extending protrusions (55, 56), which protrusions (55, 56) are located along the length of the stem at a mutual distance apart; characterized in that the method further comprises providing a guide member; wherein the guide member is substantially shaped as a stem of the prosthesis in the prosthetic cavity located in said prosthetic cement; and wherein the guide member is provided with two longitudinally running grooves (41, 42) which each are arranged to engage one of said protrusions (55, 56) of the cutting tool, wherein the grooves (41, 42) are profiled such that the outer end of the stem at which the cutting element is arranged to cut the prosthetic cement, when inserted into the prosthetic cavity and being moved to at least substantially to the bottom end thereof, will be forced to follow a path corresponding to the profile of the line of intersection of the cement/bone interface. scanning the patient in the area of the joint prosthesis so as to obtain at least one profile of a line of intersection of a prosthetic cement/bone interface at its intersection with a generally longitudinally pre-selected plane; and providing a cutting tool, the cutting tool being suitable for forming a running cut substantially completely through the prosthetic cement along the line of intersection; wherein the cutting tool comprises: an elongated stem having dimensions to be able to be inserted into a prosthetic cavity located in said prosthetic cement, at least substantially to the bottom end thereof; a cutting element arranged on said stem and arranged to cut the prosthetic cement at one outer end of said stem; a grip arranged on the other outer end of said stem for engagement of the cutting tool by an operator; and wherein the stem of the cutting tool comprises two laterally extending protrusions (55, 56), which protrusions (55, 56) are located along the length of the stem at a mutual distance apart; an elongated stem having dimensions to be able to be inserted into a prosthetic cavity located in said prosthetic cement, at least substantially to the bottom end thereof; a cutting element arranged on said stem and arranged to cut the prosthetic cement at one outer end of said stem; a grip arranged on the other outer end of said stem for engagement of the cutting tool by an operator; and wherein the stem of the cutting tool comprises two laterally extending protrusions (55, 56), which protrusions (55, 56) are located along the length of the stem at a mutual distance apart; characterized in that the method further comprises providing a guide member; wherein the guide member is substantially shaped as a stem of the prosthesis in the prosthetic cavity located in said prosthetic cement; and wherein the guide member is provided with two longitudinally running grooves (41, 42) which each are arranged to engage one of said protrusions (55, 56) of the cutting tool, wherein the grooves (41, 42) are profiled such that the outer end of the stem at which the cutting element is arranged to cut the prosthetic cement, when inserted into the prosthetic cavity and being moved to at least substantially to the bottom end thereof, will be forced to follow a path corresponding to the profile of the line of intersection of the cement/bone interface.
