A tissue holder ( ) has a first connector ( ) which can be connected to a tissue part and a second connector ( ) which can be connected to a further tissue part. The tissue holder further holds the two connectors ( ) and thus the tissue parts relative to one another. The first and second connectors ( ) each have at least one curved spike ( ) which extends around the longitudinal axis of the tissue holder ( ).

Tissue holder

An instrument ( ) for the introduction of an osteochondral transplant (P) which is removed form a harvest location, or of an implant which is correspondingly prepared in vitro at an implantation location, has a passage ( ) in which the transplant is received and a piston ( ) for the pressing out of the transplant (P) from the distal end of the passage into a depression which is prepared at the implantation location. A space for the reception of a buffer medium (F) with a high conformability and an elasticity which is dimensioned in such a manner that no bodily contact between the piston ( ) and the transplant (P) or the implant respectively exists during the pressing out of the transplant (P) is provided between the end surface ( ) of the piston ( ) facing the transplant (P) and the surface of the transplant (P) facing the piston ( ).

Instrument, instrument set and a method for the introduction of an osteochondral transplant

A knee joint prosthesis (1) comprises a tibia part (1) having a tibia bearing surface (10) and a bearing body (3) which is slidingly displaceably journalled on the tibia bearing surface (10) and which has bearing scallops (31) on its side which is remote from the tibia bearing surface (10). Furthermore, it comprises a femur part (5) which is movably arranged on the bearing scallops (31) of the bearing body (3) as well as comprising a guide piece (2) which is arranged to be rotationally fixed relative to the tibia part (1) and which permits only a displacement of the bearing body (3) in the sagittal direction relative to the tibia bearing surface (1). Furthermore, it comprises a coupling member which cooperates both with the guide piece (2) and with the femur part (5) and permits a rotation of the femur part (5) on the bearing body (3). The coupling member has a rotatably journalled pin (4) which extends in the direction of the longitudinal axis (14) of the tibia part (1) or of an axis of rotation parallel to it or in the direction of an axis which is inclined relative to the longitudinal axis of the tibia part (1) or to an axis of rotation parallel to it.
