Matles Test: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Achilles Tendon Tear:
While awake, patients are asked to actively flex their knees to 90°. When the patients are anesthetized, the examiner passively flexes both knees to 90°. In both instances, the position of the ankles and feet is observed during flexion of the knee. If the foot on the affected side falls into neutral or into dorsiflexion, an Achilles tendon tear is diagnosed. On the uninjured side, the foot remains in slight plantar flexion when the knee is flexed to 90°
