00:00:00.640 --> 00:00:06.740
Different injections are offered for knee
osteoarthritis. But the word injection can

2
00:00:06.780 --> 00:00:14.300
refer to very different preparations. We
explain three approaches: hyaluronic acid,

3
00:00:14.340 --> 00:00:20.100
cortisone and a preparation made from your
own blood. Understanding the differences

4
00:00:20.140 --> 00:00:25.720
helps you ask more specific questions
and discuss treatment with your doctor.

5
00:00:25.760 --> 00:00:29.380
Hyaluronic acid occurs naturally

6
00:00:29.420 --> 00:00:36.120
in synovial fluid and contributes to
its lubricating and elastic properties.

7
00:00:36.160 --> 00:00:42.960
A hyaluronic acid injection introduces
a preparation into the joint space.

8
00:00:43.000 --> 00:00:48.840
Products differ in molecular size,
cross-linking and concentration, among other

9
00:00:48.880 --> 00:00:55.720
things. A material property alone cannot
predict how your symptoms will develop.

10
00:00:55.760 --> 00:01:01.740
Here, cortisone refers to an anti-inflammatory
medicine from the corticosteroid

11
00:01:01.780 --> 00:01:08.410
group. It may be considered, for example,
during a flare-up with inflammation.

12
00:01:08.450 --> 00:01:13.020
Its purpose is to reduce the
inflammatory response. Whether

13
00:01:13.060 --> 00:01:17.860
treatment is suitable and whether it should
be repeated are assessed individually.

14
00:01:17.900 --> 00:01:23.380
For this treatment, blood is
first taken and processed.

15
00:01:23.420 --> 00:01:30.020
Often, the preparation is
platelet-rich plasma, or P R P.

16
00:01:30.060 --> 00:01:33.640
It contains a higher concentration of platelets,

17
00:01:33.680 --> 00:01:37.520
which can release various signalling substances.

18
00:01:37.560 --> 00:01:42.500
Preparation methods and composition
are not the same in every procedure.

19
00:01:42.540 --> 00:01:48.620
Coming from your own body does
not automatically mean risk-free.

20
00:01:48.660 --> 00:01:53.740
Some products combine hyaluronic
acid with a corticosteroid.

21
00:01:53.780 --> 00:01:59.480
This is different from a local
anaesthetic, which temporarily numbs pain.

22
00:01:59.520 --> 00:02:03.980
Ask for the exact name of the
preparation and its components.

23
00:02:04.020 --> 00:02:11.020
The term joint injection does not, on
its own, fully describe the treatment.

24
00:02:11.060 --> 00:02:17.340
The choice depends on your diagnosis,
current symptoms and previous treatments.

25
00:02:17.380 --> 00:02:21.980
Other health conditions, medicines
and personal goals also matter.

26
00:02:22.020 --> 00:02:28.120
An injection may be one part of
a treatment plan. Appropriate

27
00:02:28.160 --> 00:02:35.600
movement and muscle training remain important
parts of managing knee osteoarthritis.

28
00:02:35.640 --> 00:02:39.340
Every joint injection is a medical procedure.

29
00:02:39.380 --> 00:02:45.080
Pain or swelling may occur, and
an infection is also possible.

30
00:02:45.120 --> 00:02:50.160
Careful discussion beforehand and hygienic
technique are therefore important.

31
00:02:50.200 --> 00:02:57.620
Mention allergies, current infections
and your medicines. If you have diabetes,

32
00:02:57.660 --> 00:03:04.020
discuss a possible temporary rise in
blood sugar before a cortisone injection.

33
00:03:04.060 --> 00:03:07.220
Four questions can help at your appointment.

34
00:03:07.260 --> 00:03:11.300
What exactly will be injected? What is the aim?

35
00:03:11.340 --> 00:03:16.240
Which risks and alternatives matter to
me? And what should I consider afterwards?

36
00:03:16.280 --> 00:03:23.440
Ask the team to explain the planned
procedure and possible costs, too.

37
00:03:23.480 --> 00:03:30.100
This turns a general proposal into a
personal treatment plan you can understand.

38
00:03:30.140 --> 00:03:36.440
Crespine Gel. This information
does not replace medical advice.

39
00:03:36.480 --> 00:03:41.540
Discuss your symptoms and
treatment options with your doctor.
