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.
- Patient supine with hips flexed 90° and knees flexed 90°.
- Examiner grasps the patient heels and maximally laterally rotates the tibias.
Positive Loomer’s Test
Excess of lateral tibial rotation and posterior sag of the tibial tuberosity: Posteriolateral instability
Examiner may also perform maximal internal tibial rotation to check internal rotational stability.
