Comparative Study on Accuracy of Different Diagnostic Methods of Lateral Collateral Ligament Injury of Ankle
Background: The lateral ligament complex of ankle joint consisting of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL), and the posterior talofibular ligament (PTFL), is often injured by an ankle sprain. Improper diagnosis and treatment of lateral ligament complex injury are not only prone to recurrent sprain, pain, swelling and other symptoms, but also can lead to chronic lateral ankle instability, and osteoarthritis, which could seriously affect the joint motor function.
Method and objective: This study is a prospective diagnostic test. By comparing the sensitivity and specificity of stress X-ray, B-ultrasound, Computed tomography (CT), and Magnetic resonance imaging (MRI), and analyzing the imaging manifestations and characteristics of different diagnostic methods of lateral chronic ankle instability, We aim to propose the criteria of the imaging diagnosis of lateral ankle ligament injury.

Patients with chronic lateral ligament complex injury of the ankle were divided into 3 groups and each group with 25 cases, according to the anterior drawer test and talar tilt test.
Exclusion Criteria:
The anterior drawer test and/or talar tilt test are negative and the ankle joint is stable.
Diagnostic Test: Stress radiography,Anterior drawer test,Stress ultrasound,Computed tomography, Magnetic resonance imaging,Arthroscopy
The anterior drawer test and/or talar tilt test are slightly positive and the ankle joint is partially instable.
Diagnostic Test: Stress radiography,Anterior drawer test,Stress ultrasound,Computed tomography, Magnetic resonance imaging,Arthroscopy
The anterior drawer test and/or talar tilt test is significantly positive, with significantly instable. The ankle joint is completely instable and can featured with dimple sign.
Diagnostic Test: Stress radiography,Anterior drawer test,Stress ultrasound,Computed tomography, Magnetic resonance imaging,Arthroscopy
All patients suspected chronic ankle instability, will perform an anterior drawer test, stress ultrasound, computed tomography, magnetic resonance imaging of ankle. Patients with chronic ankle instability will be recommended to perform an arthroscopic repair if non-operative treatment failed.
