The present invention relates to a method for obtaining data indicative of
a location for ligament graft placement. Medical image data representative
of a bone is provided. Position data indicative of an intraoperative
position of each of a plurality of points associated with a surface of the
bone is obtained. The medical image data and the position data are related
to one another mathematically to obtain transformed data indicative of the
location for ligament graft placement. The present invention is also
related to a system for obtaining data indicative of a location for
ligament graft placement. The system includes a computer configured to
receive medical image data representative of a bone and a pointer or
ultrasound device configured to determine position data indicative of an
intraoperative position of one or more points associated with a surface of
the bone.
