2-minute knee check

See what the research shows for a knee like yours.

Four quick questions. You'll get a straight read on what the studies actually found for people in your situation — including where the evidence is thin. No sales pitch.

What's your age?

The studies report their results by age group.

Has a doctor told you it's "bone-on-bone"?

Or that the arthritis is end-stage. It's fine if you're not sure.

How long have you had this knee pain?

And did it build up slowly, or come on suddenly?

Have you had a cortisone or gel injection in this knee?

Cortisone, or hyaluronic ("gel").

First things first

Get this looked at before anyone injects it.

Pain that came on suddenly often isn't osteoarthritis — and an injection isn't the right first move when nobody knows what they're treating.

See your family doctor and ask for an X-ray. Once you know what's actually going on in there, come back to us — if it turns out to be arthritis, we'll be here.

One thing first — timing

Worth booking. Just not for next week.

You've had an injection in the last three months. The joint needs to settle before another one goes in — so we'd space your appointment about three months out from that last injection.

That doesn't stop you booking. Call us and we'll put you in at the right date. Nothing gets injected before the knee is ready.

Your result

The honest answer for the most advanced arthritis.

11
patients with arthritis as advanced as yours were in the main randomised trial.
That is too few to give you a percentage we'd stand behind — so we're not going to invent one. They did improve on average, and that improvement crossed the threshold doctors use for meaningful pain relief. But eleven people is not a statistic about you.1

Here's what is solid:

  • 2 yrsA separate study followed patients with moderate-to-severe arthritis, average age 70. Pain improvement was clinically meaningful and still there at two years.Peer-reviewed at 12 months — J Orthop Surg Res, 20242
  • 56%of treated knees still hadn't needed a replacement at ten years.10-year follow-up, 89 knees. Presented 20253
  • 0complications attributed to the injection across a decade of follow-up.Same 10-year study3
One thing worth knowing. "Bone-on-bone" gets used loosely. On an X-ray it covers two different grades — and patients at the earlier of the two improved just as much as those with mild arthritis, holding at five years.4 A lot of people who've been told they're bone-on-bone are actually in that group.
Your result

Patients like you responded well.

80%
of patients in your age group responded to a single injection.
Manufacturer data, drawn from the ROSA randomised controlled trial.1

One injection. In the five-year follow-up, the pain relief was still there — and across a decade of use, no complications have been attributed to the injection itself.2,3

We'll set the appointment three months from your last injection.
