The Knee

Question 1

Anterior knee pain differential diagnosis (non-traumatic)

Answer 1

Patellofemoral pain
Patella tendinopathy
Fat pad impingement
OA
Bursitis

Question 2

Traumatic knee injury differential diagnosis (Anterior)

Answer 2

ACL
PCL
Meniscus (medial and lateral)

Question 3

LCL differential diagnosis

Answer 3

Lateral meniscus
ITB syndrome
Other traumatic injury: ACL, PCL
Patella dislocation

Question 4

Is the medial or lateral meniscus more prone to injury?

Answer 4

Medial

Question 5

Role of the meniscus

Answer 5

Increase stability, distribute axial load and absorb shock

Question 6

Tibia - flexion –> Rolls and Slides?

Answer 6

Backwards (posteriorly)
RBF (Rolls & slides backwards in flexion)

Question 7

Tibia - extension –> Rolls and slides?

Answer 7

Forward (anteriorly)

Question 8

Femur - Extension? –> Rolls and slides?

Answer 8

Rolls forward (anteriorly) and slides backward

Question 9

Femur- Flexion? –> Rolls and slides?

Answer 9

Rolls backward (posteriorly) & slides forward (anteriorly)

RBF (if it rolls back in flexion, must slide forward)
**Flip it for extension ie rolls forward in ext and slides back)

Question 10

Tibia & femur externally rotate during….

Answer 10

Extension

Question 11

Tibia & femur internally rotate during…

Answer 11

Flexion

Question 12

• At around ….. degrees of flexion, the patella engages with the femoral trochlea, which is the grooved part of the femur where the patella rests
• As flexion continues to ….. degrees, the patella moves further into the trochlear groove
• When the knee is flexed at ….. degrees, the patella is deeply seated within the groove
• At …… degrees, the patella reaches its most distal (farthest) position on the femur.

Answer 12

20 Degrees
60 degrees
90 degrees
135 degrees

Question 13

MCL differential diagnosis?

Answer 13

Medial meniscus
OA
Medial plica syndrome
Pes anserine bursitis
