Abstract:
Objective To evaluate the clinical outcome of posterior cruciate ligament(PCL)recon-struction using ligament augmentation and reconstruction system(LARS)artificial ligament,and ana-lyze factors affecting the prognosis.Methods A total of 45 patients(31 males and 14 females,with an average age of 38.0±12.8 years)underwent PCL reconstruction using LARS artificial ligament in China-Japan Friendship Hospital in years from 2018 to 2021 were analyzed retrospectively.Their aver-age time from injury to surgery of 2.8±4.2 months.They were followed up for no less than 1 year about the stability of knee,Lysholm score and Tegner score,as well as the patient's satisfaction.Moreover,the effect of patient's age,time from injury to surgery,and complications of other ligament injuries of the knee on the final outcomes were analyzed.Results For all the 45 patients,the mean follow-up time was 35.0±14.1 months,with their satisfaction rate of 91.1%.There were 31 cases of 3° instability and 14 cases of 2° instability before surgery,which improved significantly as only 4 cas-es were of 2° instability,22 cases of 1° instability at the final follow-up(χ2=77.56,P<0.000).More-over,the average Lysholm and Tegner scores increased significantly from 37.2±15.2 and 0.9±0.9,to 85.3±12.7 and 4.4±1.3,respectively(t=16.34,P<0.000;t=15.72,P<0.000).What's more,the age of over 40 years had effect on the prognosis,while the time from injury to surgery and the com-plicated ligament injuries of the knee did not.Conclusion Using LARS artificial ligament as graft for PCL reconstruction can achieve satisfactory clinical results on the short-term.
