Now you may see a host
0:01
of different types of graph fixation.
0:04
These may come in the form of interference screws
0:08
or uh, staples or even cortical buttons.
0:11
Now, uh, depending on the site of fixation,
0:14
these can be subdivided into two different types.
0:18
Aperture fixation, usually via interference screws, means
0:22
that the fixation point is close to
0:24
where the graft enters the joint.
0:27
Where a suspensory fixation means
0:29
that the fixation is a ways away from
0:32
where the graft enters the joint.
0:33
So for example, cortical button at the superior aspect
0:37
of the femoral tunnel along that
0:40
lateral supracondylar ridge.
0:42
What does this mean in terms of graft motion?
0:45
Well, the closer the fixation to the,
0:48
where the graft enters the joint,
0:49
the less likelihood you're gonna have graft motion.
0:51
And this makes intuitive sense.
0:53
So if you have more of a dispensary type of fixation,
0:56
you can have, um, different types of motion.
0:59
One is referred to as bungee motion,
1:00
which is basically longitudinal motion
1:03
along the length of the graft.
1:05
Or in the other case, sagal plane motion,
1:08
which is sometimes referred to
1:09
as windshield wiper effect or motion.
1:11
And reason why motion is important to consider is
1:15
that when you have motion,
1:16
this can allow synovial intrusion into the bone tunnels,
1:20
and theoretically can result in tunnel widening over time.
