Beschreibung
Zusammenfassung:	The present invention provides a shaping guide (10, 14) to permit accurate shaping of the tibial plateau while saving the anterior cruciate ligament (11). An alignment rod (12) is located anterior to the anterior cruciate ligament and along the anterior cortex of the intramedullary canal (44) of the tibia provides points of reference for all shaping operations. The shaping guide of the present invention is adjustable with respect to the handle portion of the rod so that the amount of resection of the tibial plateau can be controlled readily by the surgeon by raising or lowering of the cutting guide surfaces for resection of the tibia.
