Method of ACL reconstruction using dual-sided rotary drill cutter
Methods and apparatus for arthroscopic tenodesis using sockets in bone created by retrograde cutting. A dual-sided rotary drill cutter is used to form a tibial and femoral socket by retrograde and antegrade cutting, respectively. The method is used to form a pair of sockets in the joint, which accept the respective ends of a replacement graft. The dual-sided cutter is configured such that it cuts in both directions (retrograde and antegrade) and does not need to be flipped over between forming the respective sockets.
1. A method of knee reconstruction comprising:
inserting a guide pin through a tibia;
attaching a dual-sided rotary cutter to the guide pin;
forming a tibial socket in the tibia by retrograde drilling;
forming a femoral socket in a femur by antegrade drilling, wherein the dual-sided rotary cutter is not removed from the guide pin between formation of the respective sockets; and
securing the ends of a graft respectively in the sockets of the tibia and femur.
2. The method of claim 1 wherein the guide pin comprises a flexible portion such that the femoral socket may be formed at an angle with respect to the tibial socket.
3. The method of claim 1 wherein forming the femoral socket further comprises aligning the guide pin using a pilot hole formed using a transtibial guide.
