Q

What are common mechanical symptoms of meniscal tears?

A

Catching sensation

or

“Locking”

20
Q

What is true knee locking ?

A

Mechanical block to full extension causes by a torn meniscus flipping over and being stuck in the joint line

21
Q

What will the patient feel if they rupture their ACL?

A

Immediatly

Rotational force

they will hear a “POP”

Haemarthrosis

Chronically

Rotatory instability

22

Lachmans test

25
Q

What is the 1/3 rule for ACL ruptures?

A

1/3 have no problems

1/3 manage by avoiding certain movements

1/3 will do poorly with frequent giving away
