A Comparative Study On The Effect Of Reconstruction Of Posterior Cruciate Ligament With Autogenous Hamstring Tendon Plus Peroneus Longus Tendon Anterior Bundle And LARS Ligament

Objective: To investigate the effect of the use of autologous hamstring tendon plus peroneal longus tendon and the application of LARS artificial ligament reconstruction of posterior cruciate ligament(PCL)knee function and recovery of mechanical stability.Methods: Forty-three patients with posterior cruciate ligament rupture were divided into two groups according to the type of graft used during the operation: the LARS artificial ligament group(22 cases)and the autologous hamstring tendon plus peroneal longus tendon group(21 cases).The postoperative follow-up time was at least two years.The knee joint function was evaluated using the knee joint Lysholm score,IKDC score,and Tegner score.The post-drawer test evaluated mechanical stability.Results: After 43 cases were followed up completely,the knee joint stability and function indexes of the two groups were significantly improved compared with preoperative ones.The differences were statistically significant(P < 0.05).At the same time,for all postoperative scores,two There was no significant difference between groups(P > 0.05).Conclusion: The application of autologous hamstring tendons plus peroneal longus tendon anterior bundle and LARS artificial ligament reconstruction posterior cruciate ligament can achieve satisfactory clinical curative effect.
