A method of providing a replacement anterior cruciate ligament (ACL)
provides a tibial tunnel and at least one femoral tunnel for receiving
the replacement ligament, the femoral and tibial tunnels not being
colinear but rather in an orientation that more closely mimics the
natural ACL. The femoral tunnel is formed through the anterior medial
portal. A cross pinning guide having a femoral rod for insertion into the
femoral tunnel, a spaced apart arc shaped track and a guide block having
one or more bores aligned with the femoral rod whereby an instrument
inserted through one of the bores creates a pilot hole for the cross pin
which intersects the femoral tunnel and an appropriate angle thereof
which avoids ligaments and other sensitive tissue can be selected by
adjusting the guide block along the track.
