  1. The Knee: Special Tests

  2. Apprehension Test • Used to test patellar femoral syndrome • Patellar tracking • With knee extended push patella laterally and create flexion to extension at knee joint • With knee extended push patella medially and create flexion to extension at knee joint • Video

  3. Lachman’s Test • ACL • PCL • Knee in slight flexion (about 20degrees) • One hand behind tibia, one hand on thigh • Pull the tibia anteriorly • Video

  4. Anterior Drawer Test • ACL • Athlete creates flexion at the knee and ATC sits on foot • Both hands behind tibia (thumbs on tibial tuberosity) • Pull tibia forward • Video

  5. Posterior Drawer Test • PCL • Athlete creates flexion at the knee and ATC sits on foot • Both hands behind tibia (thumbs on tibial tuberosity) • Push tibia posteriorly • Video

  6. Posterior Sag Sign • PCL • Position athlete in flexion • Look for a drop/sag in the leg just inferior to the patella

  7. Valgus Stress Test • MCL • Athlete lies supine on table • ATC places one hand on lateral surface of thigh and one hand on medial surface of ankle • ATC applies medial pressure on thigh and later pressure on ankle • Repeat with knee flexed to 30degrees • Video

  8. Varus • LCL • Athlete lies supine and ATC places one hand on medial surface of thigh and one hand on lateral surface of ankle • ATC applies lateral pressure on thigh and medial pressure on ankle • Repeat with knee flexed to 30 degrees • Video

  9. McMurray’s Test • Meniscus • Athlete lies supine with knee in flexion • ATC will test for medial meniscus damage by moving knee through external rotation & valgus force • ATC will test for lateral meniscus damage by moving the knee through internal rotation & varus force • Video

  10. Duck Walk • Meniscus • Have athlete squat down and walk forward and backwards a few steps • Video
