Subchondral Microfracture of Tibia After Arthroscopic Anterior Cruciate Ligament Surgery Reconstruction

Subchondral Microfracture of Tibia After Arthroscopic Anterior Cruciate Ligament Surgery Reconstruction With Two Different Drilling Techniques. Correlation With Postoperative Pain

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.

Inclusion Criteria:

• arthroscopic reconstruction surgery of an Anterior Cruciate Ligament tear

Exclusion Criteria:

• previous reconstruction of ACL
• associated lesions (meniscal tear, other ligament...)
• Refusal consent
