Consistent and accurate graft passage and interference screw guide wire placement during single incision anterior...

Misplacement and misalignment of trocar pins and guide wires during single-incision anterior cruciate ligament reconstructions can lead potentially to a number of complications. These complications include unacceptable trocar pin exit locations, difficulty repositioning the trocar pin along the initial track after unsuccessful attempts at graft passage, as well as guide wire impingement and graft transection during interference screw advancement. To help overcome these complications, a surgical technique using an eccentric aimer and two-pin passer was developed to help provide precise and repeatable placement of both a trocar pin and guide wire.
