An immediate improvement should not be expected. When the treatment is helpful, changes may develop gradually over the following weeks.
Hyaluronic Acid Knee Injections in Huddersfield
Hyaluronic acid injections are sometimes considered by people with knee osteoarthritis who continue to experience pain and restricted activity despite appropriate exercise, rehabilitation and other conservative treatment.
The treatment is not suitable for everyone, and results vary. A clinical assessment and safety screening are therefore required before an injection can be recommended.
What is a hyaluronic acid injection?
Hyaluronic acid is a substance naturally found within joint fluid. A manufactured preparation can be injected into the knee joint in a treatment sometimes known as viscosupplementation.
The aim is to potentially improve joint comfort and function for a period of time. It is not a cure for osteoarthritis, does not regrow cartilage and cannot guarantee that surgery will be avoided.
Who might it be suitable for?
Hyaluronic acid injections may be considered for selected adults with:
- Clinically diagnosed knee osteoarthritis
- Mild to moderate osteoarthritic symptoms
- Pain that limits walking, exercise or everyday activity
- Symptoms that have not improved sufficiently with rehabilitation
- A preference to explore non-surgical treatment options
The decision should take account of your symptoms, general health, previous treatment and the likely source of your knee pain.
An injection will not be recommended simply because an X-ray shows osteoarthritis.
Important information about the evidence
The evidence for hyaluronic acid injections in knee osteoarthritis is mixed. Some people report worthwhile improvements in pain and function, while others experience little or no benefit.
NICE currently advises that intra-articular hyaluronan injections should not routinely be offered for the management of osteoarthritis because the evidence has not shown consistent benefit.
Hyaluronic acid nevertheless remains available privately. If you are considering it, the limitations, possible benefits, risks and alternative options will be discussed so that you can make an informed decision.
What happens during an appointment?
The process includes:
- A discussion of your symptoms, medical history and previous treatment.
- Assessment of your knee and confirmation that an injection is a reasonable option.
- Screening for contraindications and potential risks.
- An explanation of the evidence, alternatives and expected aftercare.
- An opportunity to ask questions before providing consent.
- The injection, using an appropriate aseptic technique, if treatment is agreed.
- Advice about activity and rehabilitation following the procedure.
Depending on your clinical history, further information or medical investigation may be required before proceeding.
Potential benefits
Some people may experience:
- Reduced knee pain
- Improved comfort during walking
- Improved tolerance of everyday activity
- Greater confidence participating in rehabilitation or exercise
Benefits are not guaranteed. When an improvement occurs, the amount and duration vary considerably between individuals.
When might an injection not be suitable?
An injection may need to be avoided or postponed if you have:
- An infection or broken skin around the knee
- A current illness or fever
- A known allergy to any component of the product
- Certain bleeding disorders
- Particular medication or health conditions that increase risk
- Symptoms suggesting that osteoarthritis is not the primary problem
Please provide a full list of your medication and relevant medical history during your assessment.
Frequently asked questions
How quickly does it work?
How long do the effects last?
This varies considerably. Some people report improvement lasting several months, while others experience a shorter response or no meaningful benefit.
Is the injection painful?
Many people can drive following a knee injection, but this depends on your response and which knee is treated. You should not drive unless you can safely control the vehicle and perform an emergency stop.
Can I exercise afterwards?
You will normally be advised to avoid strenuous or high-impact activity for a short period. Specific aftercare instructions will be provided.
What are the possible side effects?
Possible effects include temporary pain, swelling, stiffness, bruising or warmth around the knee.
Infection is uncommon but potentially serious. You will be given advice about symptoms that require urgent medical attention.
Is this the same as a steroid injection?
No. Hyaluronic acid and corticosteroid injections contain different substances and are used for different reasons.
Will it prevent a knee replacement?
It is not possible to promise that an injection will prevent or delay surgery. The aim is to explore whether it can improve symptoms and activity for an individual patient.
