Restore joint comfort, without surgery
L'hyaluronic acid is a well-known solution for relieving pain associated with mild to moderate osteoarthritis. Injected directly into the joint, particularly at the knee or at the hip, it improves lubrication, reduces friction and provides lasting relief from joint discomfort.
Dr. Coulin offers this treatment in a conservative, personalized and evolving approach, when pain persists despite basic treatments such as analgesics, physiotherapy or hygiene and dietary measures.
What is hyaluronic acid?
Naturally present in synovial fluid, thehyaluronic acid It is essential for smooth movement. It acts as a lubricant and shock absorber between joint surfaces.
In the case of osteoarthritis, its quantity and quality decrease: the joint becomes less fluid, stiffer, and everyday movements (climbing stairs, walking for a long time, getting up from a chair) become painful.
The injection ofHyaluronic acid knee or hip allows:
- to improve the viscosity of the synovial fluid,
- to reduce friction and mechanical stress,
- to relieve pain, sometimes within the first few weeks,
- to delay the progression of osteoarthritis in some cases.
This therapy, also called viscosupplementationaims to restore better joint comfort without resorting to surgery.
Who is this treatment indicated for?
Dr. Coulin recommends the hyaluronic acid injections For :
- L'early or moderate osteoarthritis (primarily knee or hip).
- THE mechanical pain persistent related to movements.
- Patients who cannot tolerate anti-inflammatories or do not wish to take medication for a prolonged period.
- Those who wish avoid or postpone surgery, like a prosthesis.
This is often an option of first intention to improve quality of life, or as a temporary treatment before possible more invasive surgery.
How is an injection performed?
The injection is performed during a consultation, under strict aseptic conditions. For certain deep joints such as the hip, the procedure may be guided by ultrasound to ensure maximum precision.
The protocol varies depending on the products used:
- 1 to 3 spaced injectionsdepending on the recommendations,
- or a unique formula long-acting.
The procedure is quick, well tolerated, requires neither hospitalization nor general anesthesia, and allows for an almost immediate resumption of daily activities.
What results can you expect ?
Improvement is usually noticeable between 1 and 4 weeks after the injection, with an effect that can last from 6 to 12 months according to :
- the severity of osteoarthritis,
- the type of hyaluronic acid used,
- the patient's profile and activity.
The most common benefits are:
- A significant reduction in pain articular.
- A better tolerance to exertion (walking, stairs, active leisure).
- A reduction in the consumption of painkillers.
- A easy return to certain physical activities.
Dr. Coulin always assesses the clinical benefit before proposing a renewal of treatment.
What is the difference between PRP and stem cells?
| Treatment | Main mechanism | Average duration | Typical indication |
| Hyaluronic acid | Lubrication, comfort | 6 to 12 months | Mild or moderate osteoarthritis |
| PRP (platelet-rich plasma) | Regulation of inflammation, cellular stimulation | 6 to 12 months | Early osteoarthritis, tendonitis |
| Stem cells (BMC) | Tissue regeneration | 12 to 24 months | Localized osteoarthritis in young patients |
L'Hyaluronic acid knee It remains a simple, reliable, and effective solution. It is often used as a first-line treatment before moving on to more complex therapies such as PRP, stem cells, or, in some cases, surgery.
A targeted and scalable strategy
Treatment by hyaluronic acid is not sufficient on its own: it is part of a comprehensive care program which can be combined:
- of the physiotherapyto strengthen muscles and protect the joint,
- a gesture education, in order to avoid traumatic movements,
- a weight managementto reduce the mechanical load on the knee,
- and one regular medical check-ups to adjust the strategy according to developments.
Dr. Coulin adapts each protocol to the specific needs of the patient, with a progressive and personalized approach.
