Short Term Clinical Efficacy of Large Diameter Autologous Hamstring Tendon Reconstruction of Anterior Cruciate Ligament
Objective:To explore the effectiveness and safety of large diameter autologous hamstring tendon reconstruction of anterior cruciate ligament.Methods:Retrospective analysis of 34 patients diagnosed and treated from June 2022 to June 2023,who underwent large diameter autologous hamstring tendon reconstruction of anterior cruciate ligament.There were 30 males and 4 females with an average age of(24.32±6.41)years old.Record the length of the semitendinosus and gra-cilis muscles during surgery,as well as the diameter of the graft,IKDC score,Lysholm score,Lachman test,and axial dis-placement test of knee joint before surgery and 1 year after surgery.Results:The average effective length of the semitendi-nosus muscle is(26.04±1.33)cm.The average effective length of the gastrocnemius tendon is(21.78±2.47)cm.The av-erage diameter of the 6-strand graft is(8.85±0.28)mm,and the average diameter of the 8-strand graft is(9.75±0.26)mm.The IKDC score and Lysholm score of all patients at 12 months after surgery showed significant statistical differences compared to preoperative levels(P＜0.05).There was no significant difference in the IKDC score and Lysholm score be-tween 6 and 8 shares at 12 months after surgery(P＞0.05).Conclusion:Using large-diameter autologous hamstring ten-dons to reconstruct the anterior cruciate ligament can fully utilize the autologous hamstring tendons and ensure the diame-ter of the graft.The tibial side is fixed firmly with a double fixation method of door nail and interface screw,which has a definite therapeutic effect.
