Pediatric Meniscal Root Tear Injury Case
HIDEInteractive Transcript

So now, let's go to our case.
0:02
It's a kitty cat.
0:04
It's a child.
0:06
There's a little bit of an effusion.
0:07
Let's go right to the heart of the matter.
0:10
Let's put up our coronal projection.
0:13
It's very hard to tear anything in a child.
0:15
Because the tissues are so healthy and resilient.
0:19
There is our lateral meniscus, our root,
0:24
and our very well established beautiful
0:28
dark root ligament.
0:31
The posterior root ligament on the lateral side.
0:34
Let's go to the medial meniscus.
0:37
There's our medial meniscus posterior horn.
0:41
And there is our root ligament,
0:44
but it does not attach to the bone.
0:47
That's cortical bone. That's the root ligament.
0:50
There is a little space between the two.
0:52
Don't believe it. Let's blow it up.
0:56
There's a little space between the two.
0:58
Let's look at the next slice.
1:00
Still little space.
1:01
Let's look at the slice behind it.
1:04
There are some of those frayed,
1:07
fibrillated fibers of the root ligament.
1:09
That should flatten down on the tibia.
1:12
And look at the meniscus.
1:13
It's subtly floating upwards.
1:17
It's a child with an isolated root ligament
1:22
detachment from the medial meniscus.
1:25
So that concludes our discussion
1:27
of anchoring of the meniscus.
1:29
By demonstrating in a child detachment.
1:34
Of the medial meniscus posterior root ligament.
1:37
And to add just a little bit of fury to the case,
1:40
let's make sure we see it sagittally.
1:43
There's the root ligament on the lateral side.
1:45
Nice and flush.
1:47
Let me blow it up one more time.
1:49
Nice and flush. Right there.
1:51
Now go over to the medial side.
1:53
Sorry. Here's the medial side.
1:55
It's not so flush, is it?
1:57
That's the root ligament floating off of
2:00
its normal tibial attachment surface.
2:03
We go to the next cut up.
2:05
There's the interface between the ligament
2:07
and the meniscus. And once again,
2:09
it is not flush on the surface of the tibia.
2:12
It's a beauty.
