Study Notes

Knee Instability Tests

  • Valgus/ Abduction Stress Test: Tests for medial instability (MCL). Patient is supine with the knee in extension. The examiner applies a valgus force to the knee. A positive sign is hypermobility.

  • Varus Abduction Test: Assesses lateral instability (LCL). The patient is supine, and the examiner applies a varus force to the knee. A positive sign is hypermobility.

  • Anterior Drawer Test: Evaluates ACL instability. The patient is supine with the knee flexed to 90 degrees. The examiner stabilizes the foot and pulls the tibia anteriorly. A positive sign is hypermobility (more than 6 mm anterior translation).

  • Lachman's Test: Assesses ACL injury. Similar to the anterior drawer test; the patient is supine with the knee flexed at 30 degrees. The examiner pulls the tibia anteriorly while pushing the femur posteriorly. A positive sign is soft end-feel and hypermobility.

  • Posterior Drawer/ Sag Sign: Tests PCL instability. The patient is supine, knee flexed at 90 degrees. The examiner stabilizes the foot and pushes the tibia posteriorly. A positive sag sign indicates PCL instability. Pain and hypermobility are positive signs.

  • Slocum Test I: Examines anterolateral instability (ACL, LCL, ITB). The patient is supine with the knee flexed at 90 degrees, the hip at 45 degrees. The examiner stabilizes the foot. The examiner draws the tibia anteriorly. A positive sign includes hypermobility and pain in the lateral knee.

  • Slocum Test II: Assesses MCL/ACL instability, with the patient in the same position as Slocum test I but with 15 degrees of medial rotation. Positive findings indicate hypermobility and pain in the medial knee.

Other Knee Tests

  • Lateral Pivot Shift: Tests anterolateral instability. A positive sign is instability, potentially due to an ACL or IT band injury where the knee gives way during rotation.

  • Hughson's Posterior Drawer/ Lateral Drawer: For posterior cruciate ligament (PCL), medial collateral ligament (MCL) and lateral collateral ligament (LCL) damage.

  • Apley's Compression Test: Examines for injury of the meniscus and ligaments. A positive reaction is pain on distraction, and compression.

  • Bounce Home Test: Assesses meniscus injury and for foreign bodies within the knee joint.

  • McMurray's Test: Diagnoses a meniscal tear by causing pain.

  • Helfet's Test: Tests for impaired quadriceps.

  • Brushstroke/ Bulge Test: Identifies presence of fluid in the knee joint. A positive result is a wave of fluid.

  • Clark Sign: Tests for meniscus injury or patellofemoral problems.

  • McConnell's Test: Analyzes patellofemoral problems and pain associated with chondromalacia.

  • Walrond's Test: Identifies patellofemoral problems and pain.

  • Klieger's Lateral Rotation: Evaluates deltoid ligament and other ligament tears.

  • Talar Tilt: Checks for calcaneofibular ligament and deltoid ligament injury.

  • Fess Line Test: Checks for the instability of the medial arch.

  • Homans Test: Checks for deep vein thrombosis (DVT) in the legs.

  • Thompson Test: Assesses Achilles tendon rupture. The patient is prone and the examiner squeezes the calf.

  • Morton's Test: Analyzes metatarsal stress fracture and Morton's neuroma. The patient is supine and the examiner squeezes at the metatarsal.
