Claim 20:
21. A system for harvesting tissue material comprising bone and cartilage tissue from a body, the system comprising:
a rotary cutter defining a rotary cutter longitudinal axis extending between a rotary cutter proximal end and a rotary cutter distal end, the rotary cutter comprising:
a drive shaft configured to receive input torque; and
an osteochondral cutter configured to cut tissue and receive the tissue material in response to rotation of the osteochondral cutter under pressure against the tissue;

a bone port defining a bone port longitudinal axis extending between a bone port proximal end and a bone port distal end, the bone port comprising a bone port cannulation sized to closely fit over the osteochondral cutter; and
a trial comprising:
a trial shaft comprising:
a trial shaft proximal end comprising a handle; and
a trial shaft distal end insertable into the bone port cannulation; and

a trial tip configured to approximate a topography of a cartilage surface;

wherein:
the bone port cannulation is sized to closely fit over the trial tip; and
at least one of the bone port proximal end and the bone port distal end is securable to a bone.
