If you’ve been Googling joint injections, you’ve probably gone down a rabbit hole of brand names, molecular weights, and clinical trial abstracts that make your eyes glaze over.
Here’s the good news: you don’t need to understand all of that. That’s our job.
At Stockport Physiotherapy, we don’t reach for a single off-the-shelf product and give everyone the same injection. We’ve built a clinical toolkit of four premium hyaluronic acid (HA) products, each with a distinct profile, and we match the right one to the right person.
New to this topic? Start with our intro guide to HA injection therapy — it covers what viscosupplementation is, how it differs from a steroid injection, and who it tends to help most.
Here’s a plain-English breakdown of what we use and why it matters for you.
First — Why Does the Product Choice Matter?
All HA products work by restoring the lubricating fluid inside your joint — the stuff that gets depleted in osteoarthritis. But they differ in how they’re made, how long they stay active in your joint, and what additional benefits they bring.
Think of it like tyres. A basic tyre gets you from A to B. But the right tyre — matched to your car, your driving, and the conditions — performs completely differently. Same principle here.
| 🔵 Ostenil Plus — The Trusted Starting Point | |
| What it is | A single 40mg injection of sodium hyaluronate, enhanced with mannitol — an antioxidant that protects HA molecules from being broken down too quickly in the joint environment. |
| Best for | Patients trying HA therapy for the first time, or those with mild-to-moderate OA who want a reliable, evidence-supported option. |
| Duration | Studies support meaningful pain relief for around 6 months in good responders. |
| 🟣 Sinovial HL — The Dual-Action Option | |
| What it is | Uses NAHYCO® hybrid technology — a combination of both high and low molecular weight HA in a single injection. The two molecular sizes work together: one targeting mechanical properties of the joint fluid, the other engaging at a cellular level. |
| Best for | Patients with more established OA, or those who have had a limited response to standard HA options. Particularly useful for knee and hip. |
| Duration | Single injection; beneficial effects typically seen for around 6 months. |
| 🟢 Sinogel — When Inflammation Is Part of the Picture | |
| What it is | A gel-form HA injection containing mannitol as an antioxidant. In an arthritic joint, free radicals constantly attack and degrade HA. The mannitol in Sinogel neutralises these — protecting the HA from premature breakdown. |
| Best for | Patients with inflammatory features alongside OA; those who’ve found pure lubrication products helpful but short-lived. Good when the joint feels ‘angry’ rather than in full flare. |
| Duration | Single injection; the antioxidant mechanism may support extended benefit beyond 6 months in appropriate patients, though individual response varies. |
| 🟡 Durolane — Built to Last | |
| What it is | Uses NASHA technology (Non-Animal Stabilised Hyaluronic Acid). The HA molecules are cross-linked, engineered to resist the natural enzymes in your joint that would otherwise break them down. Also non-animal sourced. |
| Best for | Patients with knee or hip OA who want maximum duration from a single injection; those who’ve responded well to HA therapy before; patients with animal-product sensitivities. |
| Duration | Clinical studies consistently show meaningful pain relief at 6 months from a single injection. For good responders we’ve seen that extend to up to 12 months. We’ll review you along the way so we always know where you’re at. |
So How Do We Choose?
Honestly? It’s a conversation.
At your consultation, we look at which joint is involved, how advanced your OA is, what you’ve already tried, whether your joint is currently inflamed or settled, and what your lifestyle and goals look like.
Then we make a recommendation — and we explain our thinking in plain English so you’re fully on board before anything happens.
No pressure. No mystery. Just good clinical decision-making, done with you rather than to you.
