Abstract:Objective To compare the effectiveness of anterior cruciate ligament (ACL) reconstruction using RigidFix for autogenous tendons fixation between by Ethibond excel polyester sutures combined with high-strength sutures and by Ethibond excel polyester sutures. Methods From October 2011 to August 2013, 48 cases of ACL rupture underwent ACL reconstruction using RigidFix for autogenous tendons fixation. Ethibond excel polyester sutures combined with high-strength sutures were used in 25 cases (observation group) and Ethibond excel polyester sutures were used in 23 cases (control group). There was no significant difference in gender, age, side, disease duration, and preoperative Lachman test, Lysholm score, and the International Knee Documentation Committee (IKDC) score between the two groups (P > 0.05). While the treatment and rehabilitation measures were identical. Result The operation performed smoothly. Vessel, nerve and meniscus were not injured. No complication of donor site pain and myasthenia of affected knee after operation. At 6 months and 2 years after operation, the Lachman test, the Lysholm score and the IKDC score were superior significantly to those before operation in both groups (P < 0.05), but no significant difference was found(P > 0.05). Conclusion Anterior cruciate ligament reconstruction by Ethibond excel polyester sutures combined with high-strength sutures using RigidFix for autogenous tendons fixation presented satisfactory clinical results, whether using high-strength sutures during operation needs to be further study.
