Hyaluronic Acid (HA) Injections for Joint Pain: Relief, Function & Non-Surgical Care

Hyaluronic acid is a naturally occurring substance in healthy joints. It helps lubricate and cushion bones, acting as a shock absorber. In arthritis, the amount and quality of HA in joint fluid decreases, contributing to pain, stiffness, and reduced mobility.

HA injections, also called viscosupplementation, deliver synthetic or purified HA directly into the joint. This restores lubrication, reduces friction, and improves joint mechanics. While most commonly used in the knee, HA injections can also target the hips, shoulders, and other synovial joints.

According to The London Orthopaedic Clinic¹, products like OSTENIL PLUS® and Durolane are selected for their ability to provide longer-lasting relief with fewer sessions.

HA injections may be suitable if:

• Non-surgical options (physiotherapy, painkillers, lifestyle changes) haven’t provided enough relief
• You prefer to avoid surgery, or want to delay it
• Pain, stiffness, or swelling limits function, but the joint hasn’t progressed to advanced bone damage
• You want a low-risk treatment with minimal downtime

The typical process includes:

1. Assessment: Clinical evaluation and imaging to determine suitability
2. Injection: The area is cleaned and prepped. Ultrasound guidance is often used for deeper joints like the hip. Local anaesthetic may reduce discomfort
3. Onset of Relief: Some patients notice pain relief within 1–2 weeks, but full effect may take longer depending on the HA product
4. Duration: Relief can last 6–12 months, though results vary by joint, brand, and individual factors 
5. Aftercare: Rest from heavy or impact activity for a few days; gentle movement and physiotherapy are encouraged

Benefits

• Reduces pain and stiffness
• Improves joint movement and function
• Offers a non-surgical alternative when other treatments aren’t enough
• Supported by Northern Medical Practitioners¹ , HA is generally well tolerated with fewer side effects than steroids or surgery

Limitations & Risks

• Not every patient responds — relief may be modest or short-lived
• Correct product choice and injection technique are critical
• Possible mild side effects: swelling, discomfort, injection-site reactions

HA injections fall between conservative treatments (like analgesics or physiotherapy) and surgical options. Here’s a comparison:

HA injections may help delay major joint surgery, giving patients more time to explore or prepare for definitive treatment.

1. Will it hurt?
   A small sting or pressure may be felt during injection. Local anaesthetic often reduces discomfort.
   
   
2. When will I notice improvement?
   Some patients feel relief within 1–2 weeks; maximum benefit usually appears over several weeks.
   
   
3. How long does the effect last?
   Typically 6–12 months, though it can vary depending on the product, dosage, and individual response.
   
   
4. Are multiple injections needed?
   Some treatments are single-injection, while others require a series. Repeat injections are possible if clinically appropriate.
   
   
5. Is it covered by the NHS, and what are the costs?
   Coverage is limited due to NICE guidance. Private clinic fees vary by joint and HA product, often in the hundreds of pounds per injection.
