A surgical sighting instrument (1) for forming a tibial tunnel with an axis passing through two predetermined points in the knee joint, i.e. a point on the tibial plateau and a point in the region between the condyles of the femur. The distal end of the instrument is intended to be inserted into the intra-articular space and has an anchoring tip (3) designed to be placed at the femoral point and located on the axis of an alignment and guidance member (4) so that it defines therewith the axis (X-X) of the tunnel to be bored. The instrument is shaped in such a way that it may be arthroscopically inserted into the joint and adjusted therein. |
