What is it?
[Sinovial® HL] [Sinogel®]
Advanced, ultrasound-guided treatment designed to improve joint function, reduce pain, and support longer-term recovery.
An ultrasound-guided injection delivers hyaluronic acid directly into a joint to help improve lubrication, reduce pain, and support joint function.
Hyaluronic acid is a naturally occurring component of synovial fluid. We use advanced hyaluronic acid preparations from the Sinovial® HL range (IBSA), which combine high and low molecular weight hyaluronic acid. This hybrid structure is designed to improve joint lubrication, reduce inflammation, and support function.
Using ultrasound allows the clinician to visualise the joint in real time and guide the needle accurately into the correct area. This improves precision and ensures accurate delivery of the treatment.
Unlike corticosteroid injections, which primarily reduce inflammation, hyaluronic acid injections aim to improve the mechanical environment within the joint and may provide longer-lasting symptom relief in selected patients.
What can it help to treat?
Degenerative joint conditions
in hands, wrists, feet or ankles
Osteoarthritis
and age-related joint pain
Joint stiffness
causing reduced mobility

Upon arrival at our clinic on Cathedral Road, you’ll be welcomed into our waiting area by our receptionist, where you can relax while we prepare for your appointment.
2. Meet your specialist
Meet your consultant prior to your injection, and discuss your symptoms or concerns.
This is an opportunity to ask questions and ensure you feel informed and reassured before your treatment.
3. Your treatment
Using advanced, real-time ultrasound imaging, your specialist will guide the injection precisely to the treatment area.
This improves precision and ensures more accurate delivery than a "blind" injection.
4. Aftercare
You will be asked to remain in the clinic for approximately 20–30 minutes after the injection.
You’ll receive personalised aftercare advice and guidance, and if appropriate, ongoing rehabilitation can be arranged through PhysioSpace.
This service is offered on a referral-only basis.
A referral from an appropriately qualified healthcare professional is required prior to booking to ensure that treatment is appropriate and forms part of a safe, structured management plan.
Referrals are accepted from a range of healthcare professionals, including physiotherapists, general practitioners (GPs), and consultant doctors.
If you do not already have a referral, you can book a physiotherapy assessment with PhysioSpace. If treatment is clinically indicated, they can refer you directly and arrange follow-up and rehabilitation as needed.

Testimonials from our patients
Beautiful clinic, friendly staff and immediate results.
My scan really helped put my mind at ease after some worrying symptoms. I voiced my concerns and they got me in immediately for a scan and then went through the results clearly with me in the same appointment.
I like that it wasn't rushed at all and they make sure you understand everything and even send you your results after.

In depth verbal and visual feedback of my conditions were explained in detail and I was encouraged to ask as many questions as I needed.
