Indications

Loomer’s test is used to assess for posteriolateral instability of the knee joint. Also called Dial Test, Bousquet External Hypermobility Test or Tibial Lateral Rotation Test.

Procedure

  1. Patient supine with hips flexed 90° and knees flexed 90°.
  2. Examiner grasps the patient heels and maximally laterally rotates the tibias.
  3. Loomer Test - Knee orthopaedic examination

    Examiner grasps the patient heels and maximally laterally rotates the tibias.

Interpretation

Positive Loomer’s Test

Excess of lateral tibial rotation and posterior sag of the tibial tuberosity: Posteriolateral instability

Clinical notes

Examiner may also perform maximal internal tibial rotation to check internal rotational stability.
