Torsion Test

Procedure

  1. Patient seated with knee bent 90°
  2. Examiner places hand against patient’s lateral foot and instructs patient to attempt to externally rotate
  3. Procedure is repeated with the examiner placing hand against medial foot and asking the patient to internally rotate

Interpretation

Positive Torsion Test

Knee pain: Meniscal tear, moderate/severe sprain, or fracture

Clinical Notes

If a fracture is suspected it is important that the patient perform as little movement as possible with the suspect extremity, in performing this test the examiner is not looking for motion, but rather the presence of force generated against their hand.
The torsion test may be applied to other regions of the body where a fracture is suspected.
