Private Knee Replacement Cover UK

Comprehensive UK PMI policies fund the orthopaedic consultation, MRI, total or partial knee replacement and a set number of post-operative physiotherapy sessions once a knee problem is accepted. Pre-existing knee pain is usually excluded under moratorium underwriting for five years, falling away after two symptom-free years; it can be permanently excluded under full medical underwriting. NHS trauma and orthopaedics waits run well past 18 weeks for many patients.

Knee replacement on the NHS

Total or partial knee replacement is usually recommended when knee osteoarthritis causes significant pain and stiffness that hasn't responded to other treatment, as set out on the NHS knee replacement pages. The NHS describes the procedure, the typical hospital stay and the rehabilitation period, including why physiotherapy afterwards matters.

Nationally, trauma and orthopaedics — the specialty that covers knee replacement — had 851,183 people on the waiting list in August 2026, with only 60.9% seen within 18 weeks and a median wait of 13.9 weeks NHS England RTT data, August 2026, published 8 October 2026. This is not medical advice; always discuss your own treatment options with your GP or NHS consultant.

What PMI typically covers for knee replacement

Bupa By You's own brochure sets out core cover for eligible treatment by a private consultant, diagnostics and physiotherapy, and describes a dedicated 'Muscles, bones and joints' section covering fast, flexible physio access Bupa By You Brochure, April 2026.

AXA Health's plan includes an Outpatient diagnosis and care option, which also unlocks its Muscles, bones and joints service — a physio assessment without needing a GP referral first AXA Health, Muscles, bones and joints service.

The Exeter's Health+ core cover includes unlimited in-patient and day-patient treatment and up to three sessions of post-operative physiotherapy as standard, with a Therapies add-on available for further sessions The Exeter, Health+ product guide.

WPA's Complete Health IPID lists in-patient and day-patient treatment, hospital and consultant fees, and a 'Fast Track Physiotherapy' benefit of up to five sessions for self-referred physiotherapy WPA, Complete Health IPID.

• Consultant orthopaedic appointments and diagnostic imaging (X-ray, MRI).
• In-patient or day-patient surgery, including total or partial knee replacement, where the condition is covered.
• A number of post-operative physiotherapy sessions — the exact figure differs by insurer and option chosen.

What PMI typically excludes

WPA's Complete Health IPID states cover is for acute conditions that arise after you join the policy, and excludes pre-existing conditions subject to the underwriting terms agreed WPA, Complete Health IPID.

AXA Health describes its plan as covering new conditions that develop after joining, not pre-existing conditions, and confirms that out-patient drugs are not covered on its personal plan AXA Health, personal health insurance leaving a scheme page.

• Pre-existing knee conditions, per your chosen underwriting basis.
• Chronic, ongoing management of arthritis once it is no longer responding to active treatment, rather than acute flare-ups.
• Routine, non-specialist physiotherapy outside the sessions and referral route your policy specifies.

Underwriting: how a knee history is treated

Under moratorium underwriting, insurers don't ask for your medical history at application. Instead, any condition — including knee symptoms — for which you sought advice, treatment or had symptoms in a set look-back period (commonly five years) before joining is excluded, and is reinstated only after two consecutive years free of symptoms, treatment or advice for that joint Bupa, Fixed Moratorium Underwriting guide.

Under full medical underwriting, you declare your history up front and the insurer decides there and then whether to apply a personal exclusion — which can be permanent or reviewable after a stated period, depending on the insurer's assessment. See our guide to moratorium vs full medical underwriting for how the two approaches compare and which can suit different knee histories.

Joint replacement specifics

Robotic-assisted or computer-navigated knee replacement is increasingly offered at private hospitals, including centres such as the Fortius Joint Replacement Centre at Bupa Cromwell Hospital, which uses Mako robotic technology Fortius Clinic / Bupa Cromwell news release.

Whether a specific technique is funded, and whether any additional facility fee applies, is not uniformly published by every insurer — always confirm this with your insurer before booking surgery.

A note on medical advice

Our team are insurance specialists, not clinicians. This page explains how private medical insurance treats this condition; for medical advice, speak to your GP or NHS 111.

PremierPMI broker desk notes

• We tell clients with any existing knee pain not to assume cover will be in place immediately — moratorium underwriting looks back five years and needs two symptom-free years before a previously-excluded joint is covered.
• We regularly compare Bupa By You, AXA Health, Aviva Healthier Solutions, WPA Complete Health and The Exeter Health+ for clients considering knee surgery, because physiotherapy allowances and outpatient limits differ between them.
• We always ask insurers to confirm in writing exactly what is and is not included for a knee claim before a client proceeds, rather than relying on marketing pages alone.
• For clients planning a knee replacement, we check the hospital list attached to their policy tier, since not every list includes the same private hospitals.

Common questions

Does private health insurance cover knee replacement?

Comprehensive UK PMI policies cover total and partial knee replacement where the underlying knee condition developed, or was not excluded, after your policy started. Insurers assess each case against their own underwriting terms, so always check your personal policy documents or ask your insurer to confirm cover before surgery.

Will PMI cover knee replacement if I already have knee pain?

Under moratorium underwriting, any knee symptoms, advice or treatment in the five years before you joined are usually excluded until you have gone two consecutive years without symptoms, treatment or advice for that joint. Under full medical underwriting, the insurer may apply a specific, sometimes permanent, exclusion for the joint based on your declared history.

How is moratorium underwriting different from full medical underwriting for a knee condition?

Moratorium underwriting doesn't ask about your medical history up front; instead it looks back five years if you later claim, and reinstates cover after two symptom-free years. Full medical underwriting asks for your full history at application and the insurer decides there and then whether to apply a personal exclusion for your knee. See our guide to [moratorium vs full medical underwriting](/answers/moratorium-vs-full-medical-underwriting).

Is robotic-assisted knee replacement covered?

Where a comprehensive policy covers knee replacement in principle, insurers generally treat robotic-assisted and conventional techniques the same way, but authorisation and any additional facility fees should be confirmed with your insurer before the procedure, as this is not uniformly published across all providers.

How many physiotherapy sessions are included after knee replacement?

This depends on your insurer and policy tier rather than being a single industry standard. Outpatient physiotherapy is usually paid from your outpatient benefit, which may be unlimited or capped depending on the option you chose, so check your policy schedule or ask your insurer directly.

What does the NHS say about who needs a knee replacement?

The NHS explains that knee replacement is usually considered when knee pain and stiffness significantly affect quality of life and other treatments haven't helped; see the [NHS knee replacement page](https://www.nhs.uk/tests-and-treatments/knee-replacement/) for details on when it's recommended and what it involves.

Does PMI cover revision knee surgery?

If your original knee replacement was covered and the joint later needs revision surgery, this is generally treated as a continuation of an insured condition, but you should confirm this with your insurer, since terms vary between policies and underwriting types.
