We offer three hyaluronic acid injections for knee and hip osteoarthritis. This guide explains how they differ, so you can see which might suit you before your free consultation.
Hyaluronic acid is a natural part of the fluid that lubricates and cushions your joints. In osteoarthritis, that fluid becomes thinner and protects the joint less well.
A hyaluronic acid injection, sometimes called viscosupplementation, puts a gel form of it straight into the joint. The aim is to ease pain and stiffness for a period of months. It doesn’t rebuild cartilage or cure arthritis.
Treatment options
The three injections we offer
All three are single injections, given under ultrasound guidance after a free consultation.
Ostenil® Plus
£300 per joint
Hyaluronic acid with mannitol, which slows its breakdown in an inflamed joint. Used in the knee, hip and other larger joints.
Hip arthritis? Durolane® or Ostenil® Plus. Cingal® is used in the knee.
These are general pointers. We’ll recommend one after examining and scanning your joint.
The evidence
What does the research say?
The evidence for hyaluronic acid injections is mixed, and we think you should know that before you decide.
A Cochrane review of 76 trials found they improved knee pain and function compared with placebo, most clearly between about 5 and 13 weeks [1]. A later analysis of the largest trials found the benefit was small [2], and NICE advises the NHS not to offer them [3].
In practice, some people get worthwhile relief for months and others notice little. Each product page explains the research on that injection.
Who it suits
Who may benefit?
Hyaluronic acid injections may help people with mild to moderate knee or hip osteoarthritis whose pain still limits walking, sleep or exercise after trying exercise and painkillers.
They’re less likely to help a badly worn joint. In that case we’ll talk through other options, such as Arthrosamid® for the knee or a surgical opinion.

Hyaluronic acid★★★★★
I first saw Gary for a consultation regarding the arthritis in my knees with a view to having a hyaluronic acid injection. Gary was extremely knowledgeable and went through all the options before suggesting which would be the best option for me.

Knee injection★★★★★
My mum had acute knee pain which has been treated at the clinic, she now has much better mobility and positive outlook due to the treatment received. Gary has been so helpful and supportive throughout the consultation and treatment.

Cortisone injection★★★★★
I recently had an ultrasound guided cortisone injection with Gary… Gary took the time to explain everything clearly before the procedure which really put me at ease, not easy when you’re not a fan of needles! The process itself was essentially pain free.

Frozen shoulder★★★★★
Gary helped me with my frozen shoulder. He was very thorough, professional and informative. I was given a cortisone injection, which he talked me through. During the procedure he was calming and efficient.

Stem cell★★★★★
I cannot thank Gary and Gabriel enough for the stem cell treatment they gave me. When I started my treatment my tendonitis was so bad in my elbows that I couldn’t carry my little children, drive the car or do my day job without getting in severe pain.
It depends on the joint, how much arthritis there is, how quickly you want relief and whether you can have a steroid. We’ll recommend one at your free consultation and tell you the cost before you decide.
Are there any risks or side effects?
The joint can be sore, swollen or stiff for a day or two afterwards. Infection is rare. Cingal® contains a steroid, which can briefly raise blood sugar if you have diabetes. We go through your health and medicines at your consultation.
How long do they last?
It varies. Some people notice benefit for several months, others less, and some notice no difference. We’ll review how you got on before suggesting a repeat.
Can I have this on the NHS?
Usually not. NICE, which advises the NHS in England, doesn’t recommend hyaluronic acid injections for osteoarthritis, so they’re mainly available privately.
Got another question?Ask us at your consultation. You don’t have to go ahead.
