00:23
Then I went on to tear my ACL, the ligament in my knee,

ื•ืื– ืงืจืขืชื™ ืืช ื”ืจืฆื•ืขื” ื”ืฆื•ืœื‘ืช ื‘ื‘ืจืš,

ื•ืื– ืคื™ืชื—ืชื™ ื“ืœืงืช ืคืจืงื™ื ื‘ื‘ืจืš.
00:28
And I'm sure that many of you in this audience have that same story,

ืฉืœื” ื™ืฉ ื‘ื“ื™ื•ืง ืื•ืชื• ืกื™ืคื•ืจ.

So this motivated me to become an orthopedic surgeon

shouldn't we stop and ask if there's a better, more natural way?

This is the field of biologic replacements,

ื–ื”ื• ื”ืฉื˜ื— ืฉืœ ื”ื—ืœืคื” ื‘ื™ื•ืœื•ื’ื™ืช,

Kevin Stone: And so, the mission is:
35
105260
2000
ืงื•ื•ื™ืŸ ืกื˜ื•ืŸ: ืื– ื”ืžืฉื™ืžื” ื”ื™ื:

how do I treat these things biologically?

ื›ื™ืฆื“ ืžื˜ืคืœื™ื ื‘ื›ืš ื‘ืื•ืคืŸ ื‘ื™ื•ืœื•ื’ื™?
01:49
And let's talk about both what I did for my wife,
37
109260
2000
ื•ื‘ื•ืื• ื ื“ื‘ืจ ื’ื ืขืœ ืžื” ืฉืขืฉื™ืชื™ ืœืื™ืฉืชื™,

ื•ืžื” ืฉืขืฉื™ืชื™ ื‘ืžืื•ืช ืžื˜ื•ืคืœื™ื ืื—ืจื™ื.
01:53
First thing for my wife,
39
113260
2000
ื“ื‘ืจ ืจืืฉื•ืŸ ืื™ืฉืชื™,
01:55
and the most common thing I hear from my patients,
40
115260
2000
ื•ื”ื“ื‘ืจ ื”ืฉื›ื™ื— ื‘ื™ื•ืชืจ ืฉืื ื™ ืฉื•ืžืข ืžืžื˜ื•ืคืœื™ื ืฉืœื™,
01:57
particularly in the 40- to 80-year-old age group, 70-year-old age group,
41
117260
3000
ื‘ืžื™ื•ื—ื“ ื‘ืงื‘ื•ืฆืช ื”ื’ื™ืœ ืž40 ืขื“ 80 ืฉื ื”, ื‘ืงื‘ื•ืฆืช ื”ื’ื™ืœ 70,
02:00
is they come in and say,
42
120260
2000
ื”ื ื‘ืื™ื ื•ืื•ืžืจื™ื,
02:02
"Hey, Doc, isn't there just a shock absorber you can put in my knee?
43
122260
2000
"ื“ื•ืงื˜ื•ืจ, ื”ืื ื™ืฉ ื‘ื•ืœืžื™ ื–ืขื–ื•ืขื™ื ืฉืืคืฉืจ ืœืฉื™ื ื‘ื‘ืจืš?

124260
2000
ืื ื™ ืœื ืžื•ื›ืŸ ืœื”ื—ืœืคืช ืžืคืจืง."
02:06
And so for her, I put in a human meniscus allograft donor
45
126260
3000
ื•ื›ืš ืœืžืขื ื” ืฉืžืชื™ ืžื ื™ืกืงื•ืก ืื ื•ืฉื™ ืžืชื•ืจื
02:09
right into that [knee] joint space.
46
129260
2000
ื™ืฉืจ ื‘ืžืจื•ื•ื— ืฉืœ ืžืคืจืง ื”ื‘ืจืš.
02:11
And [the allograft] replaces [the missing meniscus].
47
131260
2000
[ื•ืชืจื•ืžืช ื”ืจืงืžื”] ืžื—ืœื™ืคื” [ืืช ื”ืžื ื™ืกืงื•ืก ื”ื—ืกืจ]
02:13
And then for that unstable ligament,
48
133260
2000
ื•ืœื˜ื•ื‘ืช ื”ืจืฆื•ืขื” ื”ืœื ื™ืฆื™ื‘ื”,
02:15
we put in a human donor ligament

ืื ื—ื ื• ืฉืžื™ื ืจืฆื•ืขื” ืื ื•ืฉื™ืช ืžืชื•ืจื
02:17
to stabilize the knee.

137260
2000
ื›ื“ื™ ืœื™ื™ืฆื‘ ืืช ื”ื‘ืจืš.
02:19
And then for the damaged arthritis on the surface,
51
139260
3000
ื•ืื– ืœืžืคืจืง ื”ืคื’ื•ืข ืขืœ ืคื ื™ ื”ืฉื˜ื—,
02:22
we did a stem cell paste graft,

142260
2000
ืขืฉื™ื ื• ื”ืจื›ื‘ืช ืชืื™ ื’ื–ืข ืขื•ื‘ืจื™ื™ื
02:24
which we designed in 1991,
53
144260
2000
ืœืคื™ ืชื›ื ื•ืŸ ืž1991,
02:26
to regrow that articular cartilage surface
54
146260
3000
ื›ื“ื™ ืœื’ื“ืœ ืžื—ื“ืฉ ืืช ืžืฉื˜ื— ื”ืกื—ื•ืก ื”ืžืคืจืงื™
02:29
and give it back a smooth surface there.
55
149260
3000
ื•ืœืงื‘ืœ ืฉื ืžืฉื˜ื— ื—ื“ืฉ ื•ื—ืœืง.
02:32
So here's my wife's bad knee on the left,
56
152260
2000
ื•ื”ื ื” ืจื’ืœื” ืฉืœ ืื™ืฉืชื™ ืžืฆื“ ืฉืžืืœ,

ื•ื”ื™ื ืจืฆื” ื›ื™ื•ื

02:39
And it works, not just for my wife, but certainly for other patients.

ื•ื–ื” ืขื•ื‘ื“ ืœื ืจืง ืืฆืœ ืื™ืฉืชื™, ื›ืžื•ื‘ืŸ ื’ื ืœืžื˜ื•ืคืœื™ื ืื—ืจื™ื

2000
ื ืขืฉืชื” ื”ืจื›ื‘ื” ืœื‘ืจืš

And so we can regrow these surfaces biologically.

So with all this success,
66
177260
2000
ื›ืš ืฉืขื ื›ืœ ื”ื”ืฆืœื—ื•ืช,
02:59
why isn't that good enough, you might ask.

03:02
Well the reason is because there's not enough donor cycles.

3000
ื•ื”ืจืงืžื” ื™ืงืจื” ื‘ื™ื•ืชืจ.
03:15
And so that's not going to be a solution
73

2000
ื›ืš ืฉื–ื” ืœื ื™ื›ื•ืœ ืœื”ื™ื•ืช ืคืชืจื•ืŸ

that's going to get us global with biologic tissue.

ื’ืœื•ื‘ืืœื™ ืœืจืงืžื•ืช ื‘ื™ื•ืœื•ื’ื™ื•ืช.

ืื‘ืœ ื”ืคืชืจื•ืŸ ื”ื•ื ืจืงืžื•ืช ืฉืœ ื—ื™ื•ืช

ืžื›ื™ื•ื•ืŸ ืฉื”ื ืจื‘ื™ื ื•ื–ื•ืœื™ื.

ืื‘ืœ ื”ืžื—ืกื•ื ื”ื•ื ืชื•ืจืช ื”ื—ื™ืกื•ืŸ.

2000
ื•ื”ืžื—ืกื•ื ื”ืกืคืฆื™ืคื™
