Abstract:Objective To observe the effect of arthroscopy reconstruction of anterior cruciate ligament (ACL) with autologous hamstring tendons and Rigidfix transfixion nails.Methods The clinical data of 98 patients with ACL reconstruction from January 2017 to January 2019 were retrospectively analyzed.All patients had ACL rupture by MRI before operation,and underwent arthroscopy reconstruction of autologous hamstring tendons and Rigidfix transfixion nails.The Lysholm knee function score and the International Knee Documentation Committee (IKDC) score of the ACL on the affected side were measured before and after treatment.The knee joint activity of the affected side and the healthy side were compared after treatment.Results After 1-year treatment,the Lysholm score ［(92.62±2.94)points vs (39.54±3.36)points, t=77.323, P=0.000］and IKDC score ［(84.63±3.94)points vs (27.58±4.06)points, t=64.661, P=0.000］of the affected side were significantly higher than those before treatment.After 1-year treatment,there was no statistical significance in the range of motion (flexion and extension) between the affected side and the healthy side( P>0.05).ConclusionArthroscopy treatment of autogenous hamstring tendon and Rigidfix transfixion nails for patients with ACL reconstruction can effectively improve the condition of the affected knee joint and can help the ACL.
