关节镜下LARS人工韧带在重建前交叉韧带中的临床应用

目的探讨在关节镜下运用韧带增强重建系统（LARS）人工韧带重建前交叉韧带的手术方法和临床疗效。方法 2007年6月起运用法国LARS人工韧带治疗前交叉韧带断裂14例。等距点建立胫骨和股骨骨道,置入韧带后游离纤维位于关节腔内,挤压螺钉固定。结果经平均18个月随访,术后Lysholm评分平均92分,优9例,良5例,优良率为100%。术后无感染、无韧带断裂,无膝关节疼痛。结论运用＂LARS人工韧带＂重建前交叉韧带可达到解剖重建,可有效恢复膝关节稳定性;关节镜下手术拥有创伤小、康复快、疗效好等微创特点。

Clinical report on arthroscopic reconstruction of anterior cruciate ligament with LARS artifical ligament.

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.Methods Since July 2007,14 patients with acute ACL rupture have been treated with the LARS artificial ligaments.Equidistant points,the establishment of the tibia and femur bones Road,into ligaments in the joint cavity after the free fiber,extrusion screws.Results All 14 patients were available for follow up with an average of 30 months.No postoperative complications such as infection,ligament rupture,ligament loosening occurred.The clinical results were graded as being excellent in 9 patients,good in 5 according to the Lysholm＇s classification.The excellent and good rate was 100%.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.
