- Patient lies supine. Flex the knee maximally.
- Hold the foot, grasping the heel with one hand.
- Then hold the knee joint with the other hand, placing your fingers along the medial joint line (to assess medial meniscus) and lateral joint line (to assess lateral meniscus).
- For the medial meniscus, rotate the tibia laterally together with a valgus force and at the same time extend the knee. For the lateral meniscus, rotate the tibia medially together with a varus force and at the same time extend the knee.
Positive test result: when the patient feels pain and there is an audible or palpable ‘snap’, ‘click’ or ‘thud’ during extension movement.

- Hold patient’s outstretched hands.
- The patient stands on one leg, the injured leg, with the knee flexed to 20° and foot flat on the ground.
- The patient then rotates their knee and body, medially and laterally, three times, keeping the knee at 20° flexion.
Positive test result: when the patient experiences medial or lateral joint line pain.

Joint line tenderness test
- Patient lies supine with the injured knee flexed to 90°.
- Palpate medially and laterally along the joint line between the femur and tibial condyles.
Positive test result: when the patient experiences pain during the palpation. Pain along the medial joint line indicates medial meniscus damage, and along lateral joint line indicates lateral meniscus damage.

Apley grind test
- Patient lies prone with the injured knee flexed to 90°.
- Grasp the foot with both hands, apply downwards compression pressure and at the same time rotate the tibia medially, and then laterally.
Positive test result: when there is pain and/or clicking.
