Diagnostic Study of ACL Rupture With Anterior Drawer Test at 90° of Hip Flexion

• Conditions: Anterior Cruciate Ligament Rupture
• Interventions: Diagnostic Test: anterior drawer test at 90° of hip flexion; Diagnostic Test: Lachman test; Diagnostic Test: anterior drawer test; Diagnostic Test: pivot-shift test

• Registration Number: NCT04957706
• Lead Sponsor: Peking University Third Hospital

Brief Summary

For patients with anterior cruciate ligament rupture, the existing physical examinations have certain limitations. The researchers improved the traditional anterior drawer test in clinical work, maintained the flexion of the knee and flexion of the hip, and observed the displacement of the tibia. Good diagnostic effect, but no research statistics. The purpose of this study is to explore the effectiveness of the 90° of hip flextion anterior drawer test in the diagnosis of anterior cruciate ligament rupture.

Detailed Description

A total of 300 hospitalized patients who were diagnosed with anterior cruciate ligament rupture by MR and prepared for anterior cruciate ligament reconstruction were included, of which 150 cases were injured in the acute phase (within 2 months after the injury) and the chronic phase (more than 2 months after the injury). After the patient was admitted to the hospital, the patients were sequentially subjected to the 90° anterior drawer test, Lachman test, pivot-shift test, and anterior drawer test. The examination results were recorded. Compare the effectiveness of different physical examinations in diagnosing the anterior cruciate ligament. The patient's age, gender, injury time, BMI, the type of ACL rupture in the surgical records, and whether meniscus or cartilage damage were combined were counted. Regression analysis was used to evaluate the influencing factors of the modified anterior drawer test to correctly diagnose the rupture of the ACL.
