[Objective] To introduce the surgical technique and preliminary clinical results of pullout of a three-suture net used in ar- throscopic fixation of anterior cruciate ligament (ACL) tibial avulsion fractures. [Methods] A total of 36 patients received abovementioned arthroscopic treatment for Meyer-McKeevers tye II~IV ACL tibial avulsion fractures in our hospital from January 2016 to June 2018. After a thorough arthroscopic examination through the standard anterolateral approach, a lumbar puncture needle with PDS suture was introduced crossed the anterior 1/2 of the tibial attachment base of the ACL. The first Ethibond No.2 wire was replaced and pass the ends under the transverse knee ligament to anteromedial tibial subcutaneously. After two bone tunnels were respectively drilled from the anteromedial tibi- al side to the anteromedial and anterolateral margins of the fractures, the second Ethibond No.2 wire was passed through one side tunnel, the posterior 1/2 of the tibial attachment base of the ACL and the other side bone tunnel. Then, the third suture was introduced on the first suture in the attachment. Finally, all the 3 sutures were pull out tightly, and then tied to reduce and fasten the fracture fragments firmly like a net. [Results] All patients got the operation completed successfully without related complications and infection. At last follow- up, the Lysholm, IKDC, and Tegner scores were significantly increased compared with those preoperatively (P＜0.05) . In terms of imaging, all the patients gained proper fracture reduction with fracture healing time of 12~16 weeks. [Conclusion] This arthroscopic three-suture net fixa- tion does achieve satisfactory clinical outcomes for ACL tibial avulsion fractures. with advantages of simple operation and high safety.
