Knee - Slocum Anterior Drawer

Click to Play

The Slocum Drawer test is used to assess for medial and lateral rotary instabilities of the knee.  The exam is administered similarly to the anterior drawer test with the exception that the tibia is rotated medially and laterally to assess for anterolateral and anteromedial instability respectively.  The knee is placed in approximately 90-degrees of flexion with the foot flat on the table.  Thirty-degrees of medial rotation is applied to the tibia by rotating the foot and the examiner pulls anteriorly on the tibia to assess for anterolateral rotary instability.  To examine anteromedial rotary instability the tibia is laterally rotated approximately 15-degrees and the tibia is once again pulled anteriorly.  Results are compared bilaterally.
