1. A tendon harvesting system for forming a target length of a graft from a native tendon comprising:
a guide having a first end, a second end and an elongate body therebetween; the elongate body configured to be placed along the native tendon and anteriorly spaced therefrom;
the first end being configured to engage the native tendon adjacent a patella of the native tendon;
the second end being configured to engage the native tendon at a proximal end of the target length;
a harvester including a first blade and a second blade, both of which are disposed at a leading end of the harvester with a handle extending therefrom; wherein the first blade and the second blade are configured to extend through the guide first end, and cut into and along an anterior surface of the native tendon disposed posterior to the first end, to form two lateral sides of the graft, the harvester being guided by the guide; and
an amputating tool configured to transect the native tendon at the guide second end, to form a proximal end surface of the graft.
