ABSTRACT:
Arthroscopic knee surgery is performed without a thigh incision by cutting a plug-receiving bore in the tibia, cutting a bore through the femur with a cannulated drill bit which is inserted through the tibial bore at an acute angle, and passing a wire in a proximal direction through the cannulated bit until it punctures and exits the thigh. The wire has a bend which is kept straight while it is in the cannulated bit but, upon exiting the bit, the wire's resilience restores the bend to direct the puncturing tip of the wire anteriorly toward the surface of the thigh. During the procedure, the proximal and distal ends of the wire are available to facilitate the movement of elements including a replacement graft to and from the site via the tibial bore.
