A resection guide configured to guide a tool toward a graft source, the resection guide comprising: a resection guide body elongate along a longitudinal direction and at least partially made from a first material, the resection guide body defining an upper body surface and a lower body surface that is opposite and spaced from the upper body surface along a transverse direction that is perpendicular to the longitudinal direction, wherein the lower body surface is concave with respect to and along the longitudinal direction such that the lower body surface is configured to be placed against the graft source, the resection guide body defining a first resection guide opening and a second resection guide opening that is spaced from the first resection guide opening, the first and second resection guide openings (504, 544) extending through the upper and lower body surfaces (581, 577) along the transverse direction and being elongate along first and second directions, respectively, that are perpendicular to the longitudinal direction or define an oblique angle relative to the longitudinal direction; characterised in that the resection guide further comprises a guide member configured to be at least partially inserted in at least one of the first resection guide opening or the second resection guide opening, the guide member including a guide member body, the guide member defining a guide member opening that extends through the guide member body and is elongate along a graft resection axis, the guide member opening configured to receive at least a portion of the tool such that the guide member guides a movement of the tool along the graft resection axis when the tool is received in the guide member opening, wherein the guide member is at least partially made of a second material that is harder than the first material. a resection guide body elongate along a longitudinal direction and at least partially made from a first material, the resection guide body defining an upper body surface and a lower body surface that is opposite and spaced from the upper body surface along a transverse direction that is perpendicular to the longitudinal direction, wherein the lower body surface is concave with respect to and along the longitudinal direction such that the lower body surface is configured to be placed against the graft source, the resection guide body defining a first resection guide opening and a second resection guide opening that is spaced from the first resection guide opening, the first and second resection guide openings (504, 544) extending through the upper and lower body surfaces (581, 577) along the transverse direction and being elongate along first and second directions, respectively, that are perpendicular to the longitudinal direction or define an oblique angle relative to the longitudinal direction; characterised in that the resection guide further comprises a guide member configured to be at least partially inserted in at least one of the first resection guide opening or the second resection guide opening, the guide member including a guide member body, the guide member defining a guide member opening that extends through the guide member body and is elongate along a graft resection axis, the guide member opening configured to receive at least a portion of the tool such that the guide member guides a movement of the tool along the graft resection axis when the tool is received in the guide member opening, wherein the guide member is at least partially made of a second material that is harder than the first material.
