OSCE Knee and Foot and Ankle

Question 1

What is the Q-angle?

Answer 1

• normal Q-angle 15 degrees

- females have increase Q angle b/c wider hips

Question 2

What is palpable/observable in the knee region

Answer 2

• medial/lateral tibial plateau, medial/lateral femoral condyle, adductor tubercle
• head of fibula, common fibular n
• quads muscle
• patellar tendon
• medial and lateral meniscus
• medial adn lateral collateral ligaments
• popliteal fossa

Question 3

Range of motion testing for the knee

Answer 3

-felxion= 145-150
-extension= 0-5
Internal and external rotation= 10

Question 4

What is strength testing for flexion and extension at the knee?

Answer 4

• flexion= quads, femoral n. (L2-L4)

- extension= hamstrings, sciatic n. (L5-S1)

Question 5

Wht is an adduction dysfunction of the knee?

Answer 5

-EOM with valgus force and ROM with varus

Question 6

What is the anteroposterior glide of the tibia on the femur test for and what test is it similar to?

Answer 6

• assess restriction of motion, asses ease of glide A/P

- similar to anterior drawer test but reduced force used (tests for excessive motion, ACL)

Question 7

ROM testing for ankle/foot

Answer 7

• dorsiflexion= 15-20
• plantarflexion= 50-65
• ankle inversion (talocalcaneal)= 35
• ankle eversion (talocalcaneal)= 20
• forefoot adduction= 20
• forefoot abduction= 10
• MTP flexion= 45
• MTP extension= 70-90

Question 8

Strength testing for dorsiflexion?

Answer 8

• tibialis anterior (also inverts) L4/L5
• extensor hallius longus
• extensor digitorum longus
• all deep peroneal (fibular) n. L5

Question 9

Strength testing for plantarflexion?

Answer 9

• gastrocnemius (also flexes knee)
• soleus
• flexor hallucis longus
• flexor digitorum longus
• tibialis posterior (also inverts)
• all tibial n.
