Abstract
Disclosed are femoral and tibial drill guides for use in posterior cruciate ligament replacement surgery. Each of the drill guides includes an arc shaped member and an elongate guide member, a stopper member, and an alignment arm member coupled thereto. Prior to preparing a tibial tunnel with a tibial drill guide and a femoral tunnel with a femoral drill guide, a rasp and/or cutter can be used to remove any remnants of the posterior cruciate ligament left prior to replacement thereof. The tibial drill guide includes a concave blocking surface and a viewing aperture on the alignment arm member to block the advancement and view the location of a guide pin exiting from a posterior portion of a tibia, respectively.
