First Claim
Patent Images
1. An arthroscopic drill guide for use in drilling a tunnel in a knee joint having a femur with an intercondylar roof and a trochlear groove, and a tibia having a tibial eminence, said drill guide comprising:
- a drill sleeve defining an aperture extending along a drilling axis, said aperture operable to guide a drilling procedure;
a positioning member extending from said drill sleeve, said positioning member operable to be gripped by a user; and
a guide arm having a proximal end and a distal end, said proximal end in mechanical communication with said positioning member and said distal end including a guide region, said guide region having a guide section operable to contact the trochlear groove and an extension having a distal tip operable to contact the tibial eminence and a bulbous heel positioned opposite said distal tip operable to contact the intercondylar roof of the femur.

Abstract
A drill guide for determining the site for and drilling a tunnel in a tibia during an anterior cruciate ligament replacement procedure and method for using same are also disclosed. The drill guide utilizes a multiple-point anatomical reference system for determining the most favorable position for the tibial tunnel, based on isometry, freedom from impingement and desired ACL-PCL interaction.

15. An arthroscopic drill guide for use in drilling a tunnel in a knee joint having a femur with an intercondylar roof and a trochlear groove, and a tibia having a tibial eminence, said drill guide comprising:
-
a drill sleeve defining an aperture extending along a drilling axis, said aperture operable to guide a drilling procedure; a positioning member extending from said drill sleeve, said positioning member operable to be gripped by a user; and a guide arm adjustably secured relative to said positioning member, said guide arm having a proximal end and a distal end, said proximal end being in adjustable communication with said positioning member and said distal end being substantially positioned at said drilling axis substantially throughout adjustment of said guide arm relative to said positioning member, said distal end including a distal tip operable to reference a first landmark within the knee joint and a guide surface opposite said distal tip operable to reference a second landmark within the knee joint, said guide arm having a substantially convex surface proximal of said distal tip and a substantially concave surface adjacent to said substantially convex surface, whereby said guide arm is operable to locate said drill sleeve in a desired position for drilling the tunnel by referencing the first and second landmarks within the knee joint. - View Dependent Claims (16, 17, 18, 19)
