1. A tendon harvesting system for forming a tendon graft from a native tendon comprising:
a guide and a harvesting instrument, the guide defining an elongate body with a first end and a tapered second end, the tapered second end configured to extend subcutaneously and along a longitudinal axis of the native tendon, the guide also including;
an opening configured to receive the harvesting instrument therethrough and guide access to the native tendon;
wherein the harvesting instrument includes a shaft and a cutting portion, and the guide and the harvesting instrument are configured to cooperate and define a trajectory of the harvesting instrument along the native tendon longitudinal axis, the trajectory defining a first direction, and also define a depth of cut with the cutting portion into the native tendon, the depth of cut extending in a second direction angularly offset from the first direction and thereby form a uniform tendon graft thickness.
