Trendelenburg test

Knee special test

  • Lachman test
    • Patient supine with knee flexed to 20-30 degrees; stabilize the femur and passively translate tibia anteriorly
      • Tests the integrity of the anterior cruciate ligament
    • Positive: excessive anterior translation on tibia compared to uninvolved limb
      • Test has higher sensitivity and specificity compared to anterior drawer test (preferred test)
Lachman test
Lachman test
  • Anterior drawer test
    • Patient supine with knee flexed to 45-90 degrees; therapist passively translates knee anteriorly
      • Tests the integrity of the anterior cruciate ligament
    • Positive: excessive anterior translation on tibia compared to uninvolved limb
Anterior drawer test
Anterior drawer test
  • Posterior drawer test
    • Patient in supine with knee flexed to 45 degrees; therapist passively translates tibia posteriorly
      • Tests integrity of posterior cruciate ligament
    • Positive: excessive posterior translation on tibia compared to uninvolved limb
Posterior drawer test
Posterior drawer test
  • Valgus stress test
    • Patient supine with knee resting at edge of mat; therapist applies valgus stress to the knee with knee flexed at 0 and 30 degrees
      • Tests the integrity of medial collateral ligament
    • Positive: laxity and pain compared to uninvolved side
  • Varus stress test
    • Patient supine with knee resting at edge of mat; therapist applies varus stress to knee with knee flexed at 0 and 30 degrees
      • Tests integrity of lateral collateral ligament
    • Positive: laxity and pain compared to 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 hand and the foot with another applies valgus force through a flexed knee
      • Tests the integrity of the anterior cruciate ligament
    • Positive: tibia reduction during the test by iliotibial band
Valgus test
Valgus test
  • McMurray test

    • Patient supine with knee maximally flexed; therapist passively internally rotates and extending knee- then moving to externally rotating and extending knee
      • Test lateral meniscus (internal rotation) and medial meniscus (external rotation)
    • Positive: reproduction of click, popping, or pain in knee Image #152
  • Apley’s Compression Test

    • Patient positioned prone with the knee flexed to 90 degrees. The therapist applies a downward compressive force through the heel while medially and laterally rotating the tibia.
      • Tests the integrity of menisci of the knee
    • Positive: reproduction of pain Image #155
  • Thessaly test

    • Patient standing on involved leg while holding therapist’s hands; patient rotates body and leg internally and externally with knee flexed to 5 degrees and then at 20 degrees
      • Test lateral meniscus (internal rotation) and medial meniscus (external rotation)
    • Positive: reproduction of click, popping, or pain in knee
  • Patellofemoral instability

    • Patient supine with knee flexed to 30 degrees and quadriceps are relaxed; therapist passively translates the patella laterally
      • Test for patellar instability
    • Positive: patient expresses apprehension or contracts the quadriceps muscle to prevent patellar dislocation.
  • Noble compression test

    • Patient supine with knee flexed to 90 degrees and hip flexion; therapist applies pressure 1-2cm proximal to lateral femoral epicondyle; with pressure maintaining, patient’s knee is passively extended
      • Tests the iliotibial band
    • Positive: patient experiences pain over the lateral femoral condyle
  • Ottwaa knee rules

    • Apply the Ottwa knee rules to:
      • 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 therapist answers yes to any of these questions, then imaging should be done to rule out 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

  • Anterior drawer test
    • Patient supine with foot off edge of mat; ankle in 20 degrees of plantarflexion; therapist translates talus anteriorly while stabilizing lower leg
      • Tests integrity of anterior talofibular ligament
    • Positive: excessive anterior talar translation and/or pain

Image #159

  • Talar tilt
    • Patient side-lying with knee slightly flexed and ankle in neutral position; therapist moves foot into maximal adduction (calceniofibular ligament) and abduction (deltoid ligament)
      • Tests the integrity of calcaneofibular ligament
    • Positive: laxity and/or pain

Image #160

  • Thompson’s test
    • Patient prone with foot off edge of mat; therapists squeezes calf muscle (ankle should plantarflex)
      • Tests integrity of Achilles tendon
    • Positive: no movement of foot
      • Immediate red flag if positive tests occurs- send to emergency room

Image #161

  • Windlass test
    • Weight bearing
      • Patient standing on step with toes positioned over the edge with equal weight bearing; this causes a passive extension of the first MTP joint
    • Non-weight bearing
      • Patient seated with knee flexed to 90 degrees; therapist stabilizes the ankle and passively extends the patient’s first MTP joint
        • Both tests for the presence of plantar fasciitis
    • Positive in both positions: reproduction of plantar surface pain
