The arthroscopic anterior cruciate (ACL) ligament reconstruction surgery is widespread. The creation of the tibial tunnel, retrograde or antegrade, is not consensual. A cadaveric study demonstrated tibial subchondral microfractures in the group "antegrade tibial tunnel" unlike group "retrograde tibial tunnel." To our knowledge, no clinical evaluation was performed. The investigators hypothesize that retrograde drilling will cause less local bone injury than antegrade drilling in creation of the tibial tunnel for ACL reconstruction.
