Understanding knee biomechanics: a high-load joint
Knee osteoarthritis is a complex condition involving a complex interplay of factors cartilage wear, inflammation, loss of lubrication And biomechanical alterationWhile traditional treatments primarily aim to alleviate symptoms, few of them actually change the underlying condition. the internal mechanics of the jointThis is precisely what distinguishes it. Arthrosamid®, an innovative hydrogel that acts like a durable intra-articular shock absorbercapable of improving the way the knee supports the charges, the pressures And the impacts.
This article explains in detail how Arthrosamid® influences the biomechanics of the knee, why this approach is different and which patients benefit most from it.
Understanding knee biomechanics: a joint under high stress
The knee is one of the most stressed joints in the human body. Each movement imposes significant forces on it, far exceeding the actual weight of the body.
The loads placed on the knee on a daily basis
Even with simple actions, the constraints can reach:
- Walk : ~3× body weight
- Race : 5 to 8×
- Ascent of stairs: 4 to 6×
- Squatting: maximum pressure on the cartilage
These forces are absorbed by several elements:
- THE cartilage,
- THE menisci,
- THE synovial fluid,
- and the ligaments ensuring stability and guidance.
When one of these elements is damaged, particularly the cartilage, the knee loses its ability to handle loads properly.
What happens in osteoarthritis
In osteoarthritis:
- THE cartilage thins.
- THE bone surfaces move closer together.
- THE synovial fluid loses its quality.
- THE friction forces increase.
- THE shear stress irritate the joint.
- THE peripheral nerves are stimulated by pressure.
This combination causes pain, stiffness, blockages And crackling.
The key role of synovial fluid in joint mechanics
THE synovial fluid is often underestimated, even though it plays a major role in joint comfort.
Three essential roles
It acts as:
- A nutrient vector for cartilage cells.
- A lubricant reducing friction.
- A shock absorber absorbing impacts.
In osteoarthritis, degraded synovial fluid
We observe a decrease in:
- its viscosity.
- its hyaluronate concentration.
- its damping capacity.
As a result, the knee becomes more sensitive, noisier, and more painful.
Arthrosamid®: a hydrogel that modifies the mechanical forces of the knee
Unlike traditional injections (hyaluronic acid, PRP, corticosteroids), Arthrosamid® does not act solely on inflammation.
It acts as:
- A biomechanical cushion.
- A internal shock absorber.
- A smooth interface.
- A joint stabilizer.
- a sustainable structure integrated into the joint.
1. Increase and stabilization of intra-articular volume
The hydrogel creates a stable volume inside the knee.
This results in:
- a decrease in compressive forces.
- a relief from wear areas.
- a better functional spacing articular surfaces.
This slight "detachment" reduces the pressure peaks responsible for the pain.
2. Improved joint gliding
By partially distributing itself within the joint compartment, Arthrosamid® acts as a low friction interfaceallowing:
- a smoother mobility.
- a friction reduction.
- a decrease in joint noise (creaking, crackling sounds).
3. Absorption of micro-impacts
Hydrogel has properties viscoelastic :
It absorbs impacts and releases energy gradually.
This improves:
- comfort during the walk, of the stairs or of the standing prolonged.
- there protection of the remaining cartilage.
- there knee stability.
4. Homogeneous redistribution of constraints
Arthrosamid® allows for a more balanced distribution of charges, particularly on:
- THE internal compartment (the most affected by osteoarthritis),
- the joint femorotibial,
- Sometimes patellofemoral.
This mechanical redistribution protects areas that are under excessive stress.
Why does Arthrosamid® offer lasting relief?
Osteoarthritis pain is largely due to: hyperpressure, bone-on-bone friction, shear stresses and micro-inflammations related to overload.
Osteoarthritic pain is closely linked to:
- L'hyperpressure,
- THE bone-on-bone friction,
- THE shear stress,
- THE micro-inflammations repeated.
By acting on these mechanical parameters, Arthrosamid®:
- reduced the painful signals,
- decreases nervous tension,
- calm local inflammation,
- improved stability of the knee,
- protected the remaining structures.
This is why patients generally observe a lasting effect of 2 to 5 years.
Patients who respond best to Arthrosamid®
1. Advanced mechanical osteoarthritis
Ideal for patients with: joint pinching, geodes and overload of the internal compartment.
2. Active or overweight people
These profiles exert more pressure on their knees → hydrogel improves their mechanical tolerance.
3. Stiffness, creaking, blockages
Often linked to lubrication defect or to a increased friction.
4. Patients wishing to avoid surgery
Arthrosamid® often allows delay the prosthesis while improving the quality of life.
Arthrosamid®: a different approach from all other treatments
| Hyaluronic acid | PRP | Corticosteroids | Arthrosamid® |
| → acts primarily on the viscosity of the synovial fluid. No deep mechanical action. | → acts on inflammation. No damping effect. | → purely anti-inflammatory. No biomechanical role. | → actually changes the internal mechanics of the knee. → cushions, lubricates, stabilizes, redistributes loads. → lasting and structural effect. |
Conclusion: a major advance in joint mechanics
Arthrosamid® does not simply relieve the pain:
he modifies the internal dynamics of the knee, improves the joint fluidity and reduced the mechanical stresses responsible for osteoarthritis.
This biomechanical approach provides a sustainable, comfortable solution that is particularly suitable for patients who wish to improve their daily lives without immediately resorting to surgery.
