Abstract:
Objective To explore the treatment method and clinical effect of LARS artificial ligament in treatment of combined anterior cruciate ligament(ACL) and posterior crueiate ligament (PCL) injuries of the knee under arthroscope. Methods Thirteen cases of ACL and PCL injuries were reconstructed with LARS ligament. The patients were followed up for 12-36 months. The International Knee Documentation Committee (IKDC) and Lysholm knee score scale were used for functional evaluation. In the meantime, KT-1000 was employed to check anterior and posterior laxation of the knee. Results No knee infection or limitation of knee extension occurred. Knee flexion was 105° -125° (average 117°). At termination of follow up, 10 cases (77%) was graded as A and 3 (23%) as B according to IKDC. KT-1000 examination at 25° flexion showed that the difference of anterior laxation was less than 2 mm in 12 cases and 3-5mm in 1. KT-1000 examination at 70°flexion showed that the difference of anterior laxation was less than 2mm in 12 cases and 2-4 mm in 1. The Lysholm score was (63.8±2.9) points (49459 points) before operation and (91.1 ±2.7) points (88-95 points) at follow up, with statistical difference (P ＜0.01). Conclusion Reconstruction of ACL and PCL by using LARS ligament under arthroscope is a kind of minimally invasive, safe and effective method to treat ACL and PCL injuries of the knee, with good short term outcome.
