1. Z1 K.4 OSTEO ALIGN KNEE
BRACE
The lightest treatment for
gonarthrosis there’s ever been.

2. Knee joint anatomy
1.Femur (thigh)
2.Tibia (shinbone)
3.Patella (knee cap)
4.Fibula
indirectly involved
in the knee joint
Leg anatomy

3. Knee joint anatomy
- collateral ligaments
(medial and lateral)
- cruciate ligaments
(posterior and anterior)
- menisci
(medial and lateral)
- patellar ligament

4. Knee joint anatomy

5. Function of cartilage
– even distribution of force
between different sections
of the locomotor system
– frictionless gliding of joint
surfaces

6. Cartilage
– no blood supply
– no innervation
– minimal chondrocyte activity
– minimal powers of self-
healing

7. Arthrosis
• Arthrosis is
basically the non-
inflammatory,
irreversible and
progressive
destruction of a
joint that begins
with cartilage
deterioration.

8. Arthrosis
– Risk factors
 Ageing
 Gender
 Body weight
 Strain
 Genes
 Other

9. Progressive Arthrosis
Physiological condition Initial Degeneration Advanced Degeneration Exposed Bone

10. What target groups expect of a modern relief orthosis?
easy to wear
easy to conceal
easy to put on
easy to accept

11. Light weight
• The challenge: To find a modern material with unique properties
– inherently stable
– flexible
– high quality
– production-friendly
– environmentally sound

12. 4-point stabilisation principle
• The 4-point principle provides
the knee with additional
stability and boosts patient
confidence in rediscovering
mobility and activity.
• A crucial element in the presence of
instability.

13. The correct choice of orthosis

16. The ideal patient
– one-sided gonarthrosis (III degree min.)
with chronic pain
– min. 5° and max. 15° deformity and/or
axial deviation
– reasonable degree of soft tissue tone in
the upper and lower leg
– still active; both physically and mentally
able to cope with wearing an orthosis
– realistic assessment of treatment success
