Investigators found significant improvements from preoperative measures at 24.8-month follow-up for both mean side-to-side differences and Lysholm scores in patients who underwent double-bundle ACL reconstruction using a special drill pin guide and reamer, along with a laser-guided device to facilitate a transtibial approach.

Investigators followed 24 patients with a mean age 31 years. Bone tunnel positions were evaluated using CT scans, with 3-D images obtained 2 weeks postoperatively. In addition, investigators assessed the femoral tunnel with the quadrant method and used Stäubli’s technique to assess the tibial tunnel position. At a mean final follow-up of 24.8 months, patients were evaluated using an arthrometer, range of motion, Lachman test, anterior drawer test, pivot-shift test and Lysolm score.

According to the study results the anteromedial and posterolateral tunnels were both in anatomically appropriate positions. Investigators found significant improvements in arthrometric measurements, with a mean side-to-side difference of 5.3 mm preoperatively and 0.05 mm at the final follow-up.  Mean knee extension preoperatively and postoperatively was 3° and 0.87°, respectively. Mean knee flexion was 134° preoperatively and 142.6° postoperatively.

The Lysolm score had improved significantly from preoperatively to postoperatively (56.3 points vs. 95.3 points), according to researchers. by Monica Jaramillo
