      • Tests the integrity of the posterior cruciate ligament
    • Positive: excessive posterior translation on the tibia compared to the uninvolved limb
Posterior drawer test
Posterior drawer test
  • Valgus stress test
    • Patient supine with knee resting at the edge of the mat; therapist applies valgus stress to the knee with the knee flexed at 0 and 30 degrees
      • Tests the integrity of the medial collateral ligament
    • Positive: laxity and pain compared to the uninvolved side
  • Varus stress test
    • Patient supine with knee resting at the edge of the mat; therapist applies varus stress to the knee with the knee flexed at 0 and 30 degrees
      • Tests the integrity of the lateral collateral ligament
    • Positive: laxity and pain compared to the uninvolved side
  • Pivot shift test
    • Patient supine with knee extended, hip flexed, and abducted to 30 degrees and slight internal rotation; therapist holding knee with one hand and the foot with the other applies valgus force through a flexed knee
      • Tests the integrity of the anterior cruciate ligament
    • Positive: tibia reduction during the test by the iliotibial band
Valgus test
Valgus test
  • McMurray test
    • Patient supine with knee maximally flexed; therapist passively internally rotates and extends the kne,- then moves to externally rotating and extending the knee
      • Test the lateral meniscus (internal rotation) and the medial meniscus (external rotation)
    • Positive: reproduction of click, popping, or pain in the knee
McMurray test

Noble compression test
Noble compression test
  • Ottawa knee rules

      • Rule out fracture after acute knee injury
      • Refer for imaging with one or more positive answers
      • A negative test result states there is an absence of fracture
    • If the therapist answers yes to any of these questions, then imaging should be done to rule out a fracture
      • Age 55 years or older
      • Isolated patellar tenderness without bone tenderness
      • Tenderness of the fibula head
      • Inability to flex knee to 90 degrees
      • Inability to bear weight immediately after injury

Ankle special test

    • Positive: excessive anterior talar translation and/or pain
Anterior drawer test
Anterior drawer test
  • Talar tilt
    • Patient side-lying with knee slightly flexed and ankle in neutral position; therapist moves foot into maximal adduction (calcaneofibular ligament) and abduction (deltoid ligament)
      • Tests the integrity of the calcaneofibular ligament
    • Positive: laxity and/or pain
Talar tilt
Talar tilt
  • Thompson’s test
    • Patient prone with foot off the edge of the mat; therapists squeeze calf muscle (ankle should plantarflex)

Thompson test
Thompson test
  • Windlass test
    • Weight bearing
      • Patient standing on the step with toes positioned over the edge with equal weight bearing; this causes a passive extension of the first MTP joint
