Wilson's Test


Definition/Description[edit | edit source]

The Wilson’s Test is a test used to detect the presence of Osteochondritis dissecans of the knee. [1]

Clinically Relevant Anatomy[edit | edit source]

Technique
[edit | edit source]

The test has to be performed as followed:[1]
- 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 internelly 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.[1][2]

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.
