Osteoarthrosis: Osteophytes in the Knee

HIDE
PrevNext

0:00

<v ->Now in the knee we do get peripheral osteophytes

0:04

these can become quite large.

0:06

But we also get more centrally located osteophytes

0:10

along the inner margin of the femoral condyles.

0:14

And these require description

0:17

at the time you are evaluating the imaging study,

0:21

plus you see how this affects the intercondylar facet.

0:25

And with prominent osteophytes in this region

0:29

there's an increased vulnerability

0:32

of the cruciate ligaments,

0:33

particularly the anterior cruciate ligament.

0:38

Another finding that I thought I would take

0:40

a moment to just mention is the sharpening

0:44

of what are called the tibial spines.

0:47

Well, tibial spines is not an anatomic term.

0:50

I know a lot of us use it

0:51

these are the medial and lateral tubercles

0:55

of the intercondylar eminence of the tibia.

0:58

Slight enlargement in pointing of them

1:00

has little significance

1:02

but if they become very prominent in pointing

1:06

generally that is associated with osteoarthrosis.

1:10

The cause for the pointing is not entirely clear

1:14

because nothing attaches to the tips of these tubercles.

1:19

It may relate to contact of these tubercles

1:22

with the osteophytes

1:24

that are growing along the inner aspect

1:27

of the femoral condyles.
