陈旧性前交叉韧带损伤诊治分析

目的]探讨临床检查和MRI诊断陈旧性前交叉韧带（anterior cruciate ligament，ACL）损伤的价值。方法]回顾分析65例陈旧性ACL损伤患者的诊治经过，进行临床检查，其中8例行MRI检查，最后关节镜手术确诊。结果]53例ACL完全损伤，前抽屉试验、Lachman试验和轴移试验的准确性分别为：79．2％、96．2％和92．5％；12例ACL部分损伤，前抽屉试验、Lachman试验和轴移试验的准确性分别为：16．7％、50．0％和33．3％。MRI诊断ACL损伤的准确性为100％。结论]临床检查和MRI是诊断陈旧性ACL损伤的有效方法。

Analysis of diagnosis and treatment of chronic anterior cruciate ligament injury

Objective] To evaluate the value of clinical examination and magnetic resonance imaging in diagnosing chronic anterior cruciate ligament injury. Method ] Sixty-five patients with the diagnosis of chronic anterior cruciate ligament injury were retrospectively analyzed about the course of diagnosis and treatment. To gain the primary diagnosis through clinical examination,8 patients were performed magnetic resonance imaging. Finally all the patients were carried out arthroscopic surgery to make a final diagnosis. Resnlt] Arthroscopy found 53 cases with complete anterior cruciate ligament tears, 12 cases with partial anterior cruciate ligament tears. In the complete anterior cruciate ligament tears cases,79. 2% patients had positive anterior drawer test,96.2% had positive Lachman test and 92.5 % had positive pivot shift test. In the partial anterior cruciate ligament tears cases, 16. 7% patients had positive anterior drawer test,50. 0% had positive Lachman test and 33.3 % had positive pivot shift test. The accura- cy of MRI in diagnosing anterior cruciate ligament tears was 100%. Conclusion] Clinical examination and magnetic resonance imaging can diagnose chronic anterior cruciate ligament effectively.
