| Background:The anterior cruciate ligament(ACL) injury had increased gradually in recent years. The traditional therapy can’t restore ACL’s normal anatomic relationship. If we don’t have an effective method to restore the stability of the knee, it may lead to further instability of the knee, meniscus injury, the wear injury, degeneration of articular cartilage or secondary degenerative arthritis. ACL is one of the most important static stable structure of the knee joint, which has the functions of maintaining knee’s physiological exercise as well as restricting the non physiological exercise. The technology of Arthroscopic ACL reconstruction has became more and more in common use for an increasing number of ACL injury patients. Arthroscopic ACL reconstruction has the advantages of less trauma, shorter operation time and other intra-articular combined injuries, accurate positioning, postoperative recovery quickly and fewer complications, it’s now widely used at domestic and overseas. The efficacy of ACL reconstruction is affected by many factors. Autologous tissue graft and allogeneic grafts are the most extensive reconstruction biomaterials for ACL reconstruction in the current clinical. Although existing many clinical researchs about choosing autologous tissue graft and allogeneic grafts, it that which one better is still inconclusive so far.Objective:Retrospective analysis the recently clinical efficacy of using autologous tendon or allogeneic tendon for reconstruction of ACL with Endo-button system, to provide the clinical basis for the reconstruction of ligament material selection in the reconstruction of ACL.Method:The 40 patients were chosen from 2012 May to 2014 May in Chengdu university of traditional Chinese medicine affiliated hospital orthopedic with ACL grade III injury and reconstruction of ACL, group A of autologous tendon 22 cases and group B of allogeneic tendon 18 cases. Group A using autologous hamstring tendon, and group B using allogeneic anterior tibialis tendon, the femur fixation all using Endo-button suspending, the tibial fixationusing both of biological type and ordinary screw. All patients need to record the joint activity, Lachman test results at postoperative 3 months,6 months,12 months;And assess the knee joint functional comprehensive with Lysholm and IDKC. In the postoperative 6 months,12 months to review the knee joint X-ray and MRI.Result:Two groups of patients with postoperative incision were I /healing, no infection and complications such as articular cavity hemorrhage. Allograft group patients have no obvious rejection. Two groups of patients were followed up, the follow-up time was 12-18 months, average 13.5 months.12 months after the operation, anterior drawer test, Lachman test, pivot shift test were all negative. Between the knee joint activity, IKDC scores and Lysholm score compared with preoperative, differences were statistically significant (P< 0.05) in each index comparing differences between the two groups had no statistical significance (P>0.05).Conclusion:The stability of knee in patients with ACL III degree injury has been severely damaged,with a clear indication of operation. The stability and movement function of knee can be restored by reconstruction of ACL with Endo-button system. Autologous hamstring tendon and the anterior tibial muscle allogeneic tendon in reconstruction of ACL as graft material have the exact clinical curative effect, no difference between the two recent clinical curative effect analysis of postoperative, autogenous tendon have advantages in the early recovery of knee ioint proprioception, can according to the patient’s condition and operation doctor’s preference to choose the appropriate reconstruction materials. |
