Abstract:
Objective To investigate the anatomical characteristics and clinical efficacy of femoral tunnel reconstruction in arthroscopic anterior cruciate ligament(ACL)reconstruction.Methods A total of 96 ACL tear patients treated at Guilin Hospital of Traditional Chinese Medicine Affiliated to Guangxi University of Chinese Medicine from September 2018 to October 2023 were selected as subjects.All underwent autologous peroneus longus tendon(PLT)grafting through a posteromedial approach,with femoral tunnel creation using an axial angle of 45° combined with a sagittal angle≥60°.Graft length,diameter,and tunnel dimensions were recorded in operative measurements.Coronal angle,tilt angle,and tunnel exit position measurements were measured before and after surgery.Anterior tibial distance,along with changes in International Knee Documentation Committee(IKDC),Lysholm,and Tegner scores were compared between preoperative and final follow-up.Results The average anterior tibial distance decreased from preoperative(5.8±2.3)mm to postoperative(3.3±1.6)mm.The mean IKDC score increased from(45.3±6.8)points to(85.7±5.2)points,the mean Lysholm score rose from(52.1±7.4)points to(89.6±4.9)points,and the Tegner score improved from(2.3±0.6)points to(6.5±1.1)points,with statistically significant(P<0.001).Conclusion Axial angle 45° combined with sagittal angle ≥60° drilling constructs femoral tunnels ≥ 36mm in length,which align with PLT grafting characteristics,can effectively restore patient's knee stability and motor function.
