External Rotation Recurvatum Test
The external rotation recurvatum test is the first test performed to evaluate a patient with potential posterolateral rotatory instability. In this test, the examiner determines if there is an increased amount of knee hyperextension compared to the contralateral side. The test […]
Assessment of Posterolateral Knee Instability
The posterolateral corner of the knee is a very complex area with many important structures which are intricately related to prevent both increased lateral compartment gapping and rotation. There are many different tests which are utilized to assess for posterolateral rotatory instability of the knee. While some examiners feel that the increased amount of varus […]
Anteromedial Drawer Test
The anteromedial drawer test assesses the amount of increased external rotation due to a medial knee injury. It is performed with the knee flexed to 90°, the foot in external rotation, and an anteromedial rotatory force is applied to the proximal tibia. This test is commonly confused with the posterolateral drawer test (to […]
