Definition/Description[edit | edit source]
Clinically Relevant Anatomy[edit | edit source]
Technique[edit | edit source]
The test has to be performed as follows:
- Ask the patient to sit on a table with his legs dangling over the edge.
- Bend the patient’s knee so that it is flexed at a 90° angle.
- Grasp the patient’s foot and bring the tibia in internally rotation.
- Instruct the patient to extend his leg until he/she feels pain.
The test is positive when the patient reports pain in the knee about 30° from full extension and when by rotating the foot back (externally rotation of the tibia) in it’s normal position the pain disappears.
Key Research[edit | edit source]
So far no studies have been done about the validity and the reliability of this test.
Clinical Bottom Line[edit | edit source]
Make sure the patient gradually extends his leg during the test, instead of thrusting it out quickly.
