Abstract
A coring reamer and method for creating a tibial tunnel and producing a bone graft for arthroscopic anterior cruciate ligament reconstruction. A conventional guide pin is drilled through the tibia and removed. A collared guide pin is then inserted through the guide pin tunnel until the collar abuts against the tibia. A cannulated core saw is slid over the guide pin and collar to engage the tibia. The tibial tunnel is reamed by driving the core saw into the tibia.
