[Clinical Assessment of Anterior Cruciate Ligament Rupture]

Area of Science:

• Orthopedics
• Sports Medicine
• Diagnostic Imaging

Background:

• Anterior cruciate ligament (ACL) rupture is a frequent knee injury.
• Symptoms include pain, swelling, and limited range of motion.
• Clinical examination is crucial for diagnosing ACL rupture.

Purpose of the Study:

• To review diagnostic tests for ACL rupture.
• To evaluate the diagnostic value of physical examination maneuvers.
• To compare the sensitivity and specificity of different tests.

Main Methods:

• Review of diagnostic tests for ACL rupture.
• Analysis of sensitivity and specificity data for Lachman, pivot shift, anterior drawer, and lever sign tests.
• Comparison of clinical examination findings with MRI and arthroscopy predictions.

Main Results:

• Lever sign test: Sensitivity 0.92-1.00, Specificity 0.94-1.00.
• Anterior drawer test: Sensitivity 0.18-0.92, Specificity 0.78-0.98.
• Pivot shift test: Sensitivity 0.18-0.48, Specificity 0.90-0.99.
• Lachman test: Sensitivity 0.63-0.93, Specificity 0.55-0.99.

Conclusions:

• The lever sign test, pivot shift test, anterior drawer test, and Lachman test are valuable components of the ACL examination.
• These tests aid in predicting ACL rupture when correlated with MRI and arthroscopy.
