Arthroscopic anterior cruciate ligament reconstruction by artificial ligaments: A preliminary experience / 中国微创外科杂志

ABSTRACT

Objective To study the feasibility and short-term effects of arthroscopic anterior cruciate ligament (ACL) reconstruction by using the Ligament Advancement Reinforcement System (LARS) artificial ligaments. Methods Arthroscopic ACL reconstruction was carried out in 16 patients with ACL injuries by using the LARS artificial ligaments. Bone tunnels of the femur and the tibia were prepared with an identical interval between each other. The artificial tendon was inserted into the tunnels, and then, fixed with 2 interface screws after being tightened, with the free end of the tendon within the articular cavity. The complicated injuries were treated simultaneously. Results The operation time was 51~86 min (mean, 64 min). No postoperative complications such as synovitis, ligament rupture, or movement restriction occurred. A follow-up checkup was made in the 16 patients for 1.5~6 months (mean, 3.8 months). The International Knee Documentation Committee (IKDC) scores showed 6 cases of grade C and 10 cases of grade D before the surgery, while 6 cases of grade A, 9 cases of grade B, and 1 case of grade C after the surgery ( ? 2 =6.264, P
