Comparison of the effect of anterior and posterior cruciate ligaments reconstruction between autologous ;tendon and tendon allograft / 中国基层医药

ABSTRACT

Objective To investigate the potential differences in efficacy of anterior and posterior cruciate ligaments(ACL &PCL)reconstruction by using arthroscopy between autologous tendon and tendon allograft.Methods A total of 144 patients with ACL or PCL fracture were assigned into two groups,namely anterior tibial muscle tendons allograft(n =82)and tendons autograft(n =63).The graft was fixed by using the Endobutton and Intrafix systems. The general information,drawer test,Lachman test,IKDC score,Lysholm score and Tegner score were compared between groups before and after surgery.The mean follow -up period was 16 months,ranged from 6 to 24 months. Results Both two groups received significant improvement after surgery and met the requirements of ligament reconstruction.However,those patients received autologous tendon had less complications,better knee stability.There were significant differences in Lachman score,ADT/PDT score,IKDC score[(83.43 ±4.37)points vs.(81.05 ± 4.41)points],Lysholm score [(90.59 ±3.43)points vs.(89.03 ±3.25 )points],and Tegner score [(7.79 ± 0.94)points vs.(7.37 ±0.90)points]between the two groups in 12 -month(χ2 =9.509,9.080,t =3.237,2.770, 2.729,all P <0.05).Conclusion The efficacy of autologous tendon is better than tendon allograft in anterior and posterior cruciate ligaments reconstruction,which should be considered has highest priority in treating patients with anterior or posterior cruciate ligaments fracture.
