Answer 6

increased risk of ACL injury

Question 7

What are the functions of the meniscus? (3)

Answer 7

1. Increases congruence
2. Increases articular surface area
3. Reduces WB forces

Question 8

Answer 8

Twisting & weight-bearing

Question 9

What are clinical features associated with diagnosing meniscal injury? (3)

Answer 9

1. Joint tenderness

Question 11

When should you conservatively Mx meniscal injury? (3)

Answer 11

1. Pain on McMurrays test only at full flexion. (if later, “clunk” or locking = surgical)
