HUGHSTON POSTEROMEDIAL DRAWER TEST
• Test positioning
The client lies supine with the test hip flexed to 45-degrees, knee flexed to 90-degrees, and tibia internally rotated 20 to 30-degrees.
The therapist sits on the client's foot with both hands behind the client's proximal tibia and thumbs on the tibial plateau.
• Action
Apply a posterior force to the proximal tibia.
• Positive finding
Increased posterior tibial displacement, particularly of the medial tibial condyle, as compared to the uninvolved side is indicative of posteromedial rotary instability (secondary to damage of primarily the PCL, posteromedial capsule, MCL, and posterior oblique ligament).
• Special considerations & comments
It is important to maintain quadriceps and hamstring muscle relaxation during this test.
While applying a posterior force, the therapist should carefully assess any posterior "step-off" from the tibial plateau on the femur.
