Orwyn logoorwyn™

Clinician-led. Surgeon-supported. Patient-focused.

Better decisions, together.

Orwyn puts a consultant knee surgeon's written judgement into the first-contact consultation: what is most likely going on, what to check, which test to request, what to do today, and when a surgeon is needed. Every answer shows its reasons, and the clinician decides.

Surgery when it's needed. Certainty when it's not.

Most tools built for MSK triage aim to keep people out of hospital. Orwyn helps the clinician decide when a patient should go in, when they should not, and gives the clinician and the patient a reason to trust the answer.

Step by step

See Orwyn in a consultation

Four steps from one example patient with a knee injury. No password needed.

Step 1 of 4

The safety questions come first

The clinician confirms the safety questions before anything else appears, and if a rule applies Orwyn names one clear action, where and how quickly.

The safety stop screen for an example patient with a hot, swollen knee: "Stop. A safety rule applies. A&E at once."

Step 2 of 4

The most likely diagnosis, with its reasons, and what to do today

The answer comes first, with the findings behind it, two other diagnoses to keep in mind and the actions to take today.

Step 3 of 4

Every letter written

The letter to the patient with a box for the GP, the letters to the surgeon and to physiotherapy, and the request to radiology are written, ready to check, copy or print.

The documents screen: six documents ready, with the letter to the patient shown.
Example patient
The one-page letter to the acute knee clinic, opening "Please see this 36-year-old, as we suspect an anterior cruciate ligament rupture or insufficiency."
Example patient
The MRI request to radiology, with the clinical question and the mechanism of injury.

The problem

Musculoskeletal care goes wrong in both directions

First contact clinicians already make this decision every day, and the great majority of those decisions are right. The weak part is the system around them. A patient can be sent for a surgical opinion that was never going to lead to an operation, and wait months to hear it. Another can be managed for a year with a problem that needed surgery sooner. Neither is a failure of the clinician in the room. The specialist thresholds being applied downstream, and what eventually happened to the referral, are not visible at the point the decision is made.

NHS England calls the work of getting this right MSK referral optimisation, and it is not the same as reducing referrals. We explain the terms in plain English: what MSK clinical decision support is, how MSK triage works, and who first contact practitioners are. For service leads and commissioners, we set out how NHS MSK triage works and what services are measured on.

One pathway, two ways to get it wrong From the decision at first contact there are two correct outcomes, drawn as equals: a specialist opinion now, or a credible plan without surgery. Two failures are drawn faintly: a specialist wait that changed nothing, and a delayed escalation.

What happens in the consultation

Seven steps, and the clinician decides at every one

Orwyn follows the same steps in every consultation, in the same order, with the safety questions always first. Each answer comes with its reasons in plain words, and the clinician can disagree at any point.

What Orwyn does in a consultation, in seven steps Seven steps in order. One: assess, with the safety questions first. Two: the most likely diagnosis, with its reasons. Three: a test, where one is needed. Four: what to do today. Five: when to review and when to escalate. Six: the letters are written. Seven: the outcome is returned to the clinician. Steps one to six work in the demo today. Step seven is planned, as are stored records and connection to the record system. 1 Assess safety first 2 Most likely diagnosis, with reasons 3 Test, where one is needed 4 What to do today 5 When to review, when to escalate 6 Letters written 7 Outcome returned to the clinician In the demo today Planned, with stored records and connection to the record system What Orwyn does in a consultation, in seven steps Seven steps in order.

What Orwyn is

A surgeon's criteria, written down and shown

Most patients do not need it. An experienced clinician is certain about most of the people they see, and existing triage stays exactly where it is. Every suggestion Orwyn makes comes with the reason for it, in plain words. There are no scores and no percentages. The clinician can disagree and record why, and that disagreement is kept.

Designed for the clinician

Orwyn is not a patient app and not a questionnaire the patient fills in at home. It is designed to sit with the clinician while the patient is in front of them, and to fit inside a normal appointment. This is clinician-facing decision support rather than patient self-triage, and the difference matters.

It shows its reasons

Orwyn runs on rules a named consultant surgeon has written and signed off, built from national guidance and research evidence. It is not a model whose reasoning cannot be inspected: anyone reviewing a decision can be shown why it was made. What has been tested so far.

With you, not above you

Orwyn does not check, approve or oversee the clinician's work. It carries a surgeon's judgement into a room the surgeon is not in. The clinician assesses the patient and decides.

How Orwyn was built

A collaborative answer to a complex problem

Orwyn was not designed in isolation. It was shaped by detailed conversations with the people who work in and use the musculoskeletal pathway every day: first contact physiotherapists, advanced practice physiotherapists, GPs, orthopaedic surgeons, NHS service managers, commissioners and patients. Each group sees a different part of the same problem, and each has helped shape the answer.

What they described was consistent. Good clinicians are making hard decisions without the information they need, and patients wait too long to find out whether they need a surgeon. Orwyn brings those perspectives together into one shared, written standard that every clinician can see and question.

Dr Arj Imbuldeniya

Written and governed by a named consultant knee surgeon

Orwyn is founded and led by Dr Arj Imbuldeniya, a dual fellowship-trained consultant orthopaedic knee, hip and trauma surgeon with more than 25 years in orthopaedics and musculoskeletal care. For years, physiotherapists and first contact clinicians across West London have picked up the phone or emailed him about a patient, and he has learned as much from those conversations as they have.

Questions

Four questions we are asked first

What is Orwyn?

Orwyn is surgeon-governed decision support for first-contact MSK clinicians. It puts a consultant knee surgeon's written judgement into the first-contact consultation, and the clinician decides.

Who is Orwyn designed for?

The clinician, while the patient is in front of them: first contact practitioners, advanced practice physiotherapists and MSK physiotherapists. Orwyn is not a patient app and not a questionnaire the patient fills in at home.

Is Orwyn artificial intelligence?

No. Orwyn runs on rules a named consultant surgeon has written and signed off, built from national guidance and research evidence. It is not a model whose reasoning cannot be inspected: anyone reviewing a decision can be shown why it was made.

Does Orwyn replace the clinician?

No. Orwyn does not check, approve or oversee the clinician's work. The clinician assesses the patient and makes every decision.
