Clinical effects of arthroscopic reconstruction of anterior cruciate ligament with LARS artifical ligamennt

Abstract

Objective To explore the operating methods and clinical effects of reconstruction of anterior cruciate ligament with LARS artifical ligament. Methods From October 2012 to June 2015, the clinical data of twenty-four patients with arthroscopic reconstruction of anterior cruciate ligament with LARS artifical ligamennt in Capital Medical University Beijing Friendship Hospital Pinggu Hospital were analyzed retrospectively.All patients underwent anatomical and isometric reconstruction of anterior cruciate ligament to drill femoral and tibial tunnel.The recovery of knee joint function was evaluated by Lysholm scoring system, and the clinical effect was observed. Results All 24 patients were available for follow-up with an average of (22.5±1.5) months.No wound infection occurred during the period.Joint instability and weak leg symptoms and knee pain were obviously improved, the scope of joint activities was increasing.The Lysholm scores improved from a preoperative score of (40.20±1.26) points to postoperative (92.20±2.18)points, and the difference between the two groups was statistically significant (t=2.156, P<0.05). According to the modified Lysholm scoring standard, among 24 cases, 15 cases were excellent, 7 cases were good, 2 cases were fair, and the excellent and good rate was 91.6% (22/24). Conclusion The reconstruction of the anterior cruciate ligament with LARS artificial ligament has the advantages of small trauma, definite curative effect and less complications.It can achieve the purpose of anatomic reconstruction of the anterior cruciate ligament and can effectively restore the stability of the knee joint.
