  1. Normal active knee extension range of motion is approximately:

    Answer: 0°

    Normal knee extension is 0° (full extension), with hyperextension beyond 0° considered hypermobile.

  2. Which special test is used to assess the anterior cruciate ligament (ACL)?

    Answer: Lachman test

    The Lachman test is the most sensitive clinical test for ACL integrity, performed with the knee at 20–30° of flexion.

  3. A PTA is treating a patient post-total knee arthroplasty. Which motion is typically most restricted early post-op?

    Answer: Flexion

    Knee flexion is typically most restricted early after total knee arthroplasty due to swelling, pain, and surgical healing.

  4. The Thomas test is used to identify tightness in which muscle group?

    Answer: Hip flexors

    The Thomas test assesses hip flexor tightness by observing if the non-tested leg rises off the table during the test.

  5. Which fracture pattern is most common in osteoporotic vertebral compression fractures?

    Answer: Wedge compression fracture

    Wedge compression fractures are most common in osteoporosis, occurring at the anterior vertebral body.

  6. Which ligament is primarily stressed with a valgus force at the knee?

    Answer: Medial collateral ligament

    A valgus (medially directed) force stresses the medial collateral ligament on the inside of the knee.
