An instrument (2, 3) 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 (201, 301) in which the transplant is received and a piston (31) 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 (31) and the transplant (P) or the implant respectively exists during the pressing out of the transplant (P) is provided between the end surface (311) of the piston (31) facing the transplant (P) and the surface of the transplant (P) facing the piston (31).
