Knee pain can make everyday activities such as walking, climbing stairs, exercising, or standing for long periods difficult.
When knee pain is caused by osteoarthritis, treatment may include exercise, physiotherapy, weight management where appropriate, medicines, and, in selected patients, injections.
Hyaluronic acid injections, also known as viscosupplementation, are one non-surgical treatment that may be considered for some people with symptomatic knee osteoarthritis.
Research suggests that some patients may experience improvements in pain and function, although the degree of benefit varies and clinical guidelines differ on their routine use.
This blog explains how hyaluronic acid injections work, their potential benefits and risks, and who may be considered for treatment.
It also explains what to expect during and after the procedure and how hyaluronic acid injections compare with corticosteroid injections.
What are Hyaluronic Acid Injections for Knee Pain?
Hyaluronic acid is a naturally occurring substance found in the body.
It is particularly found in the synovial fluid present in various joints.
In the knee, hyaluronic acid helps the fluid lubricate and absorb shock.
Hyaluronic acid injections are intra-articular injections delivered directly into the knee joint for people with symptomatic knee osteoarthritis.
Whether these injections are suitable depends on your diagnosis, symptoms, disease severity, previous treatment, and overall health.
It is important to understand that hyaluronic acid injections are primarily used for symptom management.
They are not a guaranteed way to restore damaged cartilage or reverse osteoarthritis.
How Does Hyaluronic Acid Work in the Knee Joint?
Hyaluronic acid is naturally present in synovial fluid.
It contributes to the fluid's viscoelastic and lubricating properties.
Injected hyaluronic acid is intended to supplement these properties within the joint.
It may also influence the local joint environment.
However, hyaluronic acid injections do not regenerate damaged cartilage or reverse osteoarthritis.
What are the Benefits of Using Hyaluronic Acid for Knee Pain?
Hyaluronic acid injections may offer potential benefits for selected people with knee osteoarthritis:
- Potential pain relief: Hyaluronic acid injections have shown improvements in pain and function in some people with knee osteoarthritis, although the average benefit varies between studies and individuals.
- Improved knee function: Reduced pain may make walking and exercise easier.
- Non-surgical option: An injection can be considered before or alongside other treatment approaches in selected patients.
- May support rehabilitation: Reduced symptoms may help some patients participate more comfortably in exercise or physiotherapy.
A hyaluronic acid knee injection may be considered as part of a broader treatment plan rather than as a standalone solution.
Who Can Be a Candidate for Knee Hyaluronic Acid Injections?
Hyaluronic acid injections are not recommended for everyone with knee pain.
A qualified physician may consider hyaluronic acid injections when your symptoms, diagnosis, previous treatments, and treatment goals indicate that an injection may be appropriate.
A few factors that the physician will consider before considering hyaluronic acid injection for your knee pain include:
- The cause of your knee pain
- Severity and duration of symptoms
- Findings after a thorough physical examination
- Previous injuries or surgery
- Imaging findings where clinically indicated
- Previous treatments and their effectiveness
- Current medications and medical conditions
- Functional limitations
- Individual treatment goals
Hyaluronic acid may be considered, particularly when a patient wants a non-surgical option, but that does not mean it is automatically appropriate.
At Hortman Clinics, the aim is to identify the underlying cause of knee symptoms before recommending an intervention.
Who May Not Be Suitable for a Hyaluronic Acid Knee Injection?
Hyaluronic acid injections may not be recommended or suitable for people with knee pain who:
- Are suspected to have a joint infection
- Have an infection at the injection site
- Have an unexplained acute knee problem requiring further evaluation
- Have a known allergy or hypersensitivity to a preparation or product
- Have other medical factors that make an injection inappropriate
What to Expect During Hyaluronic Acid Injection Treatment at Hortman Clinics, Dubai?
At Hortman Clinics, the procedure usually begins with a clinical assessment to confirm that an intra-articular injection is appropriate.
On the day of the procedure:
- The physician cleans the skin around the knee with an appropriate antiseptic or aseptic preparation.
- They use a needle to administer the hyaluronic acid preparation into the knee joint.
- Depending on the clinical situation and equipment available, the injection may be performed with ultrasound guidance, as it helps the physician visualize relevant anatomical structures and support accurate needle placement.
The procedure is generally quick.
Your clinician will provide instructions about activity and aftercare following the procedure.
At Hortman Clinics, we assess treatment suitability individually.
The clinician will discuss expected benefits, limitations, potential risks, alternatives, and aftercare before proceeding.
What Can You Expect After the Injection?
After receiving a hyaluronic acid injection in the knee joint, you may experience the following temporary effects around the injection site:
- Mild soreness
- Swelling
- Stiffness or discomfort
These symptoms usually last a few hours to a couple of days and resolve on their own.
Always follow specific aftercare instructions provided by your physician.
Your physician will give a few post-procedure instructions to support healing and reduce side effects, such as avoiding or modifying strenuous activity temporarily before gradually returning to normal activities.
Pain relief following a hyaluronic acid injection in the knee joint is not necessarily immediate.
Some people may notice improvement over the following days or weeks, while others may experience limited benefit.
However, if you develop significant or worsening pain, marked swelling, fever, redness, or other concerning symptoms after an injection, contact your physician immediately.
Are Hyaluronic Acid Injections Safe?
Hyaluronic acid injections are generally well tolerated, but like any injection, they can cause side effects and complications.
These may include temporary pain, swelling, warmth, stiffness, or inflammation around the injection site.
Rare but more serious complications, such as infection, can occur.
Your physician should discuss the potential benefits and risks before treatment.
Appropriate patient assessment, sterile or aseptic technique, and post-treatment monitoring by a licensed physician are therefore important to reduce the risk of side effects.
Hyaluronic Acid vs Cortisone Injections for Knee Pain
When discussing injectables for knee joint pain, it is essential to differentiate between cortisone and hyaluronic acid injections.
-
Cortisone (Corticosteroid) injections
These are commonly used for short-term relief of inflammation and pain in knee osteoarthritis.
Corticosteroid injections generally have a faster onset of pain relief than hyaluronic acid injections, although the response varies between individuals.
-
Hyaluronic acid injections
Hyaluronic acid injections are intended to supplement the properties of the joint's synovial fluid and may provide symptom relief over a different time course.
They may take longer to produce symptom relief, with some patients noticing improvement over the following days or weeks.
Neither treatment is universally suitable, and clinical guidelines differ in their assessment of injectable treatments.
The best choice depends on the patient's diagnosis, symptoms, treatment history, and goals.
A consultation can help determine which options suit your situation.
Are Hyaluronic Acid Injections a Replacement for Knee Replacement Surgery?
No. A hyaluronic acid injection is a non-surgical treatment with the primary intention of temporarily managing symptoms such as pain and stiffness.
It does not replace knee replacement surgery when severe joint disease requires surgical management.
Treatment decisions should be based on the severity of the disease, symptoms, functional limitations, previous treatment, and the individual's overall health.
For people with advanced osteoarthritis who have significant functional limitations, or whose symptoms remain uncontrolled despite appropriate non-surgical treatment, an orthopedic assessment is recommended.

Hyaluronic acid injections are a non-surgical treatment option that may be considered for selected people with symptomatic knee osteoarthritis.
Suitability is determined after an individual assessment of symptoms, functional limitations, previous treatments, and treatment goals.
The treatment delivers hyaluronic acid directly into the knee joint and may reduce pain and improve function in some individuals.
Because this treatment is patient-specific and not suitable for everyone with knee osteoarthritis, our physician at Hortman Clinics will assess your knee pain.
Your physician will discuss non-surgical and other treatment options and determine whether a hyaluronic acid injection is appropriate for your condition.
If persistent knee pain is affecting your mobility or daily activities, a medical assessment can help identify the cause and determine which treatment options may be appropriate for you.
