NOTE Confidence: 0.8629012

00:00:07.060 --> 00:00:08.780
Usually you have two bones

NOTE Confidence: 0.8629012

00:00:08.780 --> 00:00:10.500
that make up the joints.

NOTE Confidence: 0.8629012

00:00:10.500 --> 00:00:12.558
So for example the knee joint.

NOTE Confidence: 0.8629012

00:00:12.560 --> 00:00:14.432
You have the femur and the

NOTE Confidence: 0.8629012

00:00:14.432 --> 00:00:16.515
tibia and the bones and the

NOTE Confidence: 0.8629012

00:00:16.515 --> 00:00:18.410
joint are lined with cartilage.

NOTE Confidence: 0.8629012

00:00:18.410 --> 00:00:20.318
That's what lets the bones glide

NOTE Confidence: 0.8629012

00:00:20.318 --> 00:00:22.383
against each other and arthritis that

NOTE Confidence: 0.8629012

00:00:22.383 --> 00:00:24.945
cartilage has become damaged or worn down.

NOTE Confidence: 0.8629012

00:00:24.950 --> 00:00:25.294
Unfortunately,

NOTE Confidence: 0.8629012

00:00:25.294 --> 00:00:28.390
we don't have a way to repair the cartilage.

NOTE Confidence: 0.8629012

00:00:28.390 --> 00:00:30.105
The cartilage has a very

NOTE Confidence: 0.8629012

00:00:30.105 --> 00:00:31.134
unique complex architecture.

NOTE Confidence: 0.8629012

00:00:31.140 --> 00:00:33.180
So when the cartilage has been

NOTE Confidence: 0.8629012

00:00:33.180 --> 00:00:34.893
severely damaged to the point

NOTE Confidence: 0.8629012

00:00:34.893 --> 00:00:36.591
that pain is causing a decrease

NOTE Confidence: 0.8629012

00:00:36.591 --> 00:00:38.709
in in a patient's activity,

NOTE Confidence: 0.8629012

00:00:38.710 --> 00:00:40.768
then the next step would be

NOTE Confidence: 0.8629012

00:00:40.768 --> 00:00:42.150
a total joint replacement.

NOTE Confidence: 0.8956745

00:00:46.130 --> 00:00:48.170
So total joint replacement is

NOTE Confidence: 0.895674499999999

00:00:48.170 --> 00:00:51.074
when we replace the surfaces where

NOTE Confidence: 0.895674499999999

00:00:51.074 --> 00:00:53.882
the cartilage has been broken down

NOTE Confidence: 0.895674499999999

00:00:53.882 --> 00:00:57.010
or worn out and we replace it with

NOTE Confidence: 0.895674499999999

00:00:57.095 --> 00:01:00.239
metal or plastic or ceramic surfaces.

NOTE Confidence: 0.895674499999999

00:01:00.240 --> 00:01:01.880
Everyone's anatomy is unique,

NOTE Confidence: 0.895674499999999

00:01:01.880 --> 00:01:05.705
so the shape of your bone is going to

NOTE Confidence: 0.895674499999999

00:01:05.705 --> 00:01:07.850
be different from everyone else's.

NOTE Confidence: 0.895674499999999

00:01:07.850 --> 00:01:11.906
So you would want to put the implants

NOTE Confidence: 0.895674499999999

00:01:11.906 --> 00:01:14.547
in specifically for you so that.

NOTE Confidence: 0.895674499999999

00:01:14.550 --> 00:01:17.598
Surgery is customized specifically for you.

NOTE Confidence: 0.895674499999999

00:01:17.600 --> 00:01:21.264
I take a high resolution CAT scan or

NOTE Confidence: 0.895674499999999

00:01:21.264 --> 00:01:25.649
MRI and I create a 3D representation of

NOTE Confidence: 0.895674499999999

00:01:25.649 --> 00:01:28.806
your joint. From that 3D representation,

NOTE Confidence: 0.895674499999999

00:01:28.806 --> 00:01:32.444
I'm able to model different implant sizes

NOTE Confidence: 0.895674499999999

00:01:32.444 --> 00:01:35.923
and positions and orientations in your knee,

NOTE Confidence: 0.895674499999999

00:01:35.930 --> 00:01:39.493
and I'm able to select the optimal

NOTE Confidence: 0.895674499999999

00:01:39.493 --> 00:01:42.550
position of those components and then

NOTE Confidence: 0.895674499999999

00:01:42.550 --> 00:01:45.350
construct 3D printed custom instruments.

NOTE Confidence: 0.895674499999999

00:01:45.350 --> 00:01:46.628
Before your joint.

NOTE Confidence: 0.88343614

00:01:51.830 --> 00:01:54.648
The way it's been done is that

NOTE Confidence: 0.88343614

00:01:54.650 --> 00:01:56.665
surgeons have used different alignment

NOTE Confidence: 0.88343614

00:01:56.665 --> 00:01:58.680
orientation guides during the surgery

NOTE Confidence: 0.88343614

00:01:58.680 --> 00:02:02.307
and we know that they're not as precise or

NOTE Confidence: 0.88343614

00:02:02.310 --> 00:02:04.325
accurate during the surgery than

NOTE Confidence: 0.88343614

00:02:04.325 --> 00:02:06.340
if you use this technology.

NOTE Confidence: 0.81532377

00:02:10.510 --> 00:02:13.760
We know that patients who have

NOTE Confidence: 0.81532377

00:02:13.760 --> 00:02:16.032
had these custom instruments.

NOTE Confidence: 0.81532377

00:02:16.040 --> 00:02:18.140
Day after surgery, say that the

NOTE Confidence: 0.81532377

00:02:18.140 --> 00:02:20.549
knee or hip feels more natural.

NOTE Confidence: 0.92253554

00:02:23.550 --> 00:02:25.350
They require less blood

NOTE Confidence: 0.92253554

00:02:25.350 --> 00:02:26.700
transfusions after surgery,

NOTE Confidence: 0.92253554

00:02:26.700 --> 00:02:28.950
that their pain is less.

NOTE Confidence: 0.92253554

00:02:28.950 --> 00:02:31.005
We know that there's fewer

NOTE Confidence: 0.92253554

00:02:31.005 --> 00:02:32.649
readmissions to the hospital

NOTE Confidence: 0.92253554

00:02:32.649 --> 00:02:34.349
using these instruments,

NOTE Confidence: 0.92253554

00:02:34.350 --> 00:02:36.600
so there are big differences

NOTE Confidence: 0.92253554

00:02:36.600 --> 00:02:38.850
in terms of patient outcomes.
