Abstract
A surgical drill for providing holes at an angle for use in repair and replacement of the ACL is disclosed, generally comprising a drill guide having a head that is angularly adjustable with respect to a body, a flexible guide pin and a flexible drill. The adjustable head of the drill guide allows a surgeon to drill a hole in the femur at an angle to a tunnel provided in the tibia. Because the surgeon can access the femur via the hole in the tibia, the surgical drill of the present invention obviates the need for a second hole in the tissue and also makes placement of femur hole more precise for securement of the ligament or tendon graft within the hole.
