Clinical report on arthroscopic reconstruction of anterior cruciate ligament with LARS artifical ligament / 中国矫形外科杂志

ABSTRACT

[Objective]To explore the operating methods and rudimental clinical effects of reconstruction of anterior cruciate ligament(ACL) with the ligament advancement reinforcement system(LARS) artificial ligaments under arthroscope.[Method]Since June of 2006,15 patients(11 males and 4 females,with an average age of 26.8 years)with acute ACL rupture have been treated with the LARS artificial ligaments.The results of preoperative Arto-scan of all patients suggested discontinuation of ACL.The average score of Lysholm on knee joint was 50 points.The operations were completed under arthroscope.Bone tunnels of the femur were located at the central point of arc on the medial surface of ectocondyle of 140 degree.Bone tunnels of tibia were located between the medial and lateral condyle on the tibial plateau、2-4 mm to summit line of fossa intercondylica.The diameter of the bone tunnels was 7.5 mm while that of LARS ligament and hollow crushing screw were 8 mm.[Result]All 15 patients were available for follow-up with an average of 18 months.No postoperative complications such as infection,ligament rupture,ligament loosening occurred.The clinical results were graded as being excellent in 8 patients,good in 5 and fair in 2 according to the Lysholm's classification.The excellent and good rate was 86.6%.[Conclusion]The anatomical reconstruction and the stability of the knee joint can be obtained after ACL reconstruction with LARS artificial ligaments.The operation under arthroscope has advantages of less-injury,rapid recovery and satisfactory curative effect.
