If you’re reading this, there’s a good chance you’ve been dealing with joint pain for longer than you’d like to admit.
Maybe you’ve tried rest, anti-inflammatories, and physiotherapy. Maybe you’ve had a steroid injection that helped for a while but didn’t last. Maybe you’ve been told to “manage it” and come back when it’s bad enough for surgery.
That gap — between where you are now and a knee replacement — is exactly where we work.
At Stockport Physiotherapy, we offer hyaluronic acid (HA) injection therapy, also known as viscosupplementation. It’s a treatment that’s been available for decades but that many patients have never been told about. If that’s you, read on.
What’s Actually Happening Inside Your Joint
In a healthy joint, the fluid surrounding your cartilage is rich in hyaluronic acid. This gives it two key properties — it’s viscous at slow speeds (think walking, climbing stairs) and elastic at faster speeds (think running, stepping off a kerb quickly). It also keeps the cartilage hydrated and protects the joint from wear.
In an arthritic joint, this fluid deteriorates. It becomes thinner, less effective, and the joint loses the cushioning it was built with. More wear, more friction, more pain.
Viscosupplementation is the process of restoring that lost HA through a direct injection into the joint — giving it back the environment it needs to function better.
How Is This Different From a Steroid Injection?
Both have a role — and we use both at Stockport Physiotherapy, depending on what your joint needs right now.
Corticosteroid injections are brilliant at rapidly reducing inflammation. They work quickly and are often the right first step, particularly if your joint is hot, swollen, or in an acute flare.
HA injections work differently. Rather than targeting inflammation directly, they work by restoring the joint environment — improving lubrication, supporting cartilage health, and addressing the underlying quality of the joint fluid. They take a little longer to get going, but the effects tend to be more sustained. For good responders, that can mean meaningful relief for 6 months or longer — with some patients doing well for up to 12 months before needing to think about their next treatment.
They’re not competitors. They’re different tools for different situations — and sometimes we use them together.
The Products We Use
We don’t use a generic, off-the-shelf approach. We carry four clinically recognised HA formulations — including Ostenil Plus and Durolane — and we select the right one based on your joint, your history, and your goals.

The short version is: the product matters, and we take that choice seriously. You can also find full details of our injection therapy service — including how to book — on our HA Injection Therapy page [link to Ostenil page].
Who Is This Treatment For?
HA injections tend to work best for people who:
- Have mild-to-moderate osteoarthritis in the knee, hip, shoulder, or ankle
- Have tried physiotherapy and medication but haven’t got where they want to be
- Had a steroid injection that helped but wore off sooner than hoped
- Want to delay or avoid surgery without just white-knuckling the pain
- Are looking for a treatment with a longer duration of effect
It’s not the right choice for everyone — which is why we always start with a thorough assessment. But for the right patient, it can be genuinely life-changing.
If knee osteoarthritis is specifically your concern, we’ve written a more focused piece on that here — including what the evidence shows, which products we tend to use for knee OA, and what your appointment actually looks like.
What Happens at Your Appointment?
No GP referral needed. You come in, we listen, we assess your joint properly, and we talk you through all your options — including whether HA therapy is actually the right call for you right now.
If it is, the injection itself takes just a few minutes. Most people are back to normal activity within 24–48 hours. We follow you up, track your response, and plan ahead together.
No jargon. No pressure. Just honest, expert care in Stockport.
