Most people with osteoarthritis have never read the guideline that shapes their care, which is entirely reasonable — they’re written for clinicians, not patients.
But the current one contains several things that genuinely surprise people, including some that contradict what they’ve been doing for years.
NICE published its guideline on osteoarthritis in over 16s in October 2022. Here’s what it actually says, in plain terms.
One thing to be clear about first: nothing here is a recommendation to change your medication. Some of what follows concerns drugs you may have been taking for a long time, and those conversations belong with your GP. This is background so the conversation is better informed.
You Probably Don’t Need an X-ray
What the guideline says: osteoarthritis can be diagnosed clinically, without imaging, in someone aged 45 or over who has activity-related joint pain and either no morning stiffness or morning stiffness lasting under 30 minutes.
X-rays are reserved for cases with red flags or where surgery is being planned.
Why this surprises people: many arrive expecting a scan and interpret not getting one as being taken less seriously.
Why it’s actually sensible: what appears on an X-ray correlates poorly with symptoms. Substantial changes can accompany modest pain, and modest changes can accompany considerable pain. The image often adds anxiety without changing management — and the phrase “wear and tear” delivered alongside it changes how people move for years.
The exception matters though. That diagnostic shortcut assumes a typical picture. Morning stiffness lasting well over 30 minutes, several small joints involved symmetrically, or symptoms that improve with movement and worsen with rest point elsewhere — potentially towards inflammatory arthritis, which needs a different pathway and where early diagnosis genuinely matters.
Exercise Isn’t Advice. It’s the Treatment.
What the guideline says: therapeutic exercise is a core treatment, offered to everyone with osteoarthritis, alongside weight management where relevant. Not as something to try while waiting for the real intervention — as the intervention.
What “therapeutic exercise” means specifically: local muscle strengthening for the affected joint, and general aerobic fitness. Tailored to the individual.
Why the distinction matters: “core treatment” carries a different weight from “you should try to stay active.” One is a prescription. The other is a suggestion, and it’s frequently delivered as one.
Two honest caveats worth knowing. First, exercise can hurt initially and that’s expected rather than a sign of harm — the guideline explicitly addresses explaining this to people. Second, the evidence is stronger for some joints than others, with knee osteoarthritis better supported than hip.
And on weight: the guidance is that any amount of weight loss is likely to be beneficial, and that people should be supported to choose their own goal. That’s a considerably kinder framing than the target-driven version many people have encountered.
The Paracetamol Section
This is the one that stops people.
What the guideline says: clinicians should explain that there is no strong evidence of benefit for paracetamol in osteoarthritis. It advises against routinely offering paracetamol or weak opioids, unless they’re used infrequently for short-term relief and all other pharmacological options are contraindicated, not tolerated, or ineffective.
Why this is surprising: paracetamol has been the default first step for osteoarthritis for decades, and a great many people take it regularly on that basis.
Important context before you do anything with this: the committee noted circumstances where paracetamol may still be appropriate — some people can’t take anti-inflammatories at all, and for them the calculation is different. Guidance also varies internationally.
What to do with it: not stop taking anything unilaterally. If you’ve been taking paracetamol daily for years with limited benefit, that’s worth raising at your next appointment. If it genuinely helps you, that’s relevant information too.
Glucosamine
What the guideline says: don’t offer it. The committee found the evidence inconsistent, with the largest apparent benefits coming from smaller, lower-quality studies.
Why it matters: this is a considerable amount of money spent across a lot of people, on something the national guideline explicitly advises against.
Topical Before Oral
What the guideline says: if medication is needed, topical NSAIDs — anti-inflammatory gels — come first, particularly for knee osteoarthritis. Oral NSAIDs are reserved for when topical preparations don’t adequately control symptoms.
And when oral anti-inflammatories are used: they should be at the lowest effective dose, with gastroprotection such as a proton pump inhibitor, and with kidney function, heart failure risk and bleeding risk considered.
Why the order matters: topical delivers the drug locally with far less systemic exposure, which matters increasingly with age and with other health conditions.
The “Do Not Offer” List
Worth knowing, because several of these are still widely available and sometimes recommended:
Strong opioids — not offered for osteoarthritis. Risks outweigh benefits.
Glucosamine.
Acupuncture and electrotherapy for osteoarthritis.
Hyaluronan injections.
Arthroscopic lavage — the “wash out” procedure.
If any of these are proposed to you specifically for osteoarthritis, that’s a reasonable point to ask what evidence supports it in your case.
Steroid Injections
What the guideline says: consider intra-articular corticosteroid injections when symptoms aren’t controlled by other approaches — while being aware they’ll likely provide only short-term relief.
How to read that: as a window, not a solution. An injection that gives you eight weeks of reduced pain is genuinely useful if you spend those eight weeks building strength. Used as a standalone treatment, it buys time rather than changing anything.
Joint Replacement
What the guideline says: consider referral for knee, hip or shoulder replacement when symptoms substantially affect quality of life and non-surgical management has been ineffective or is unsuitable.
The phrase doing the work is “has been ineffective.” That assumes non-surgical management was actually delivered — and a substantial proportion of people referred for an orthopaedic opinion have never completed a structured strengthening programme for the affected joint.
If you’re approaching that conversation, it’s worth knowing whether you’ve had a genuine trial of the core treatment or a brief one.
What This Adds Up To
The guideline’s centre of gravity has shifted decisively away from medication and towards exercise and weight management as the primary treatment, with drugs playing a supporting role — topical first, oral second, several previously common options withdrawn entirely.
Which means the most evidence-based thing available for most people with osteoarthritis is a properly delivered exercise programme. It’s also the thing most commonly not received.
When to See Your GP Rather Than Manage It
Book an appointment for morning stiffness lasting well over an hour; several joints swelling symmetrically, particularly small joints; symptoms that improve with movement and worsen with rest; joint pain alongside feeling generally unwell, fever, weight loss or rashes; a joint that’s hot, red and acutely swollen, which needs same-day assessment; or symptoms that are progressing rapidly.
Get the Core Treatment, Properly
If exercise is the treatment, it’s worth having one that’s actually tailored, progressed and reviewed rather than a sheet of exercises.
Ed Voss Physio offers a free discovery visit at no cost and no obligation. You’ll get a thorough assessment of your joints, strength and function, a clear explanation of what’s driving your symptoms, and a progressive programme built around what you want to be able to do.
If your presentation suggests something needing GP review or referral, we’ll tell you plainly.
