Analysis of diagnosis and treatment of chronic anterior cruciate ligament injury / 中国矫形外科杂志

ABSTRACT

[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.[Result]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 accuracy of MRI in diagnosing anterior cruciate ligament tears was 100%.[Conclusion]Clinical examination and magnetic resonance imaging can diagnose chronic anterior cruciate ligament effectively.
