Arthroscopic Two-Point Suture Bridge Fixation Technique for the Treatment of Anterior Cruciate Ligament Tibial Avulsion Fractures

This study aimed to present and evaluate a new arthroscopic technique that uses two-point suture fixation for anterior cruciate ligament (ACL) tibial avulsion fractures. A total of 15 patients diagnosed with ACL tibial avulsion fracture underwent arthroscopic suture fixation from November 2018 to October 2019 and were treated using two-point suture fixation. The patients were followed up and evaluated according to Lysholm scores, International Knee Documentation Committee (IKDC) subjective scores, Tegner activity level scales, anterior drawer testing, and KT-1000 arthrometer testing. The mean follow-up period was 18 months (12 to 24). All patients had a negative Lachman test and anterior drawer test at final follow-up and showed the radiological union of avulsion fracture at 12-week postoperative radiograph. The Lysholm score improved significantly postoperatively with a mean score of 94.26 +/- 3.63 (87 to 98; p < 0.001). The Tegner score improved significantly postoperatively from 3.61 +/- 1.37 to 7.14 +/- 1.51 (p < 0.001). The KT-1000 measured value decreased significantly postoperatively from 7.3 11.5 to 1.4 11.2 (p < 0.001). The IKDC category was abnormal or severely abnormal preoperatively, and all patients improved to normal or nearly normal at final follow-up. Arthroscopic treatment using the two-point suture fixation technique is effective for ACL avulsion fracture and can restore the function and stability of the knee joint.

Automated summary

The study demonstrates that arthroscopic treatment using the two-point suture fixation technique is effective for ACL avulsion fractures, restoring knee joint function and stability.
