WeCovr's patient guide to accessing knee surgery through PMI
Living with chronic knee pain can be debilitating. It affects your mobility, your work, and your quality of life. While the NHS provides excellent care, long waiting lists for orthopaedic surgery can mean months, or even years, of pain and uncertainty. This is where private medical insurance (PMI) can be a lifeline.
This comprehensive guide explains everything you need to know about using private health cover to access knee replacement surgery in the UK. We’ll break down the costs, the process, and the crucial details about how insurance policies work, especially concerning conditions like osteoarthritis.
Why Consider Private Knee Replacement Surgery?
The primary driver for many people choosing private healthcare is the desire to bypass lengthy waiting times. As of early 2025, the NHS is still working through a significant backlog of elective surgeries that built up over the past few years.
According to NHS England data, the median waiting time for trauma and orthopaedic treatment—the specialty that covers knee replacements—can be several months from referral. Many patients wait much longer than the 18-week target. This extended wait can lead to a deterioration in your condition, increased pain, and a greater reliance on painkillers.
Choosing the private route offers several distinct advantages:
- Speed: You can often see a specialist within days and schedule surgery in a matter of weeks.
- Choice: You can choose your consultant surgeon and the hospital where you'll be treated.
- Comfort: You are almost certain to have a private room with an en-suite bathroom, offering more peace and quiet during your recovery.
- Flexibility: You can schedule your surgery at a time that suits you, minimising disruption to your life and work.
Here’s a simple comparison of the typical patient journeys:
| Feature | NHS Pathway | Private Pathway (with PMI) |
|---|---|---|
| Initial Referral | GP refers you to a local NHS hospital trust. | GP refers you to a consultant of your choice from your insurer's list. |
| Waiting Time | Can be many months, often exceeding 18 weeks. | Typically a few weeks from referral to surgery. |
| Choice of Surgeon | You are treated by the surgical team on duty. | You choose your specific consultant surgeon. |
| Choice of Hospital | Limited to your local NHS trust's options. | You can choose from a nationwide list of private hospitals. |
| Accommodation | Usually a shared ward. | A private, en-suite room is standard. |
| Post-op Physio | May have waiting lists for NHS physiotherapy. | Access to private physiotherapy is often included in your cover. |
Understanding Knee Replacement Surgery
A knee replacement, or 'arthroplasty', is a surgical procedure to replace the weight-bearing surfaces of a damaged knee joint to relieve pain and disability. It's one of the most common and successful operations in modern medicine.
There are two main types:
- Total Knee Replacement (TKR): The entire joint is replaced with an artificial prosthesis. This is the most common type.
- Partial Knee Replacement (PKR): Only one damaged compartment of the knee is replaced. This is a less invasive option suitable for a smaller number of patients.
Surgery is usually recommended when knee pain from conditions like osteoarthritis or rheumatoid arthritis becomes severe and no longer responds to other treatments like physiotherapy, injections, or medication.
The Critical Role of Private Medical Insurance (PMI)
This is the most important part of our guide. Understanding how insurance works is key to a successful claim.
The Golden Rule: Acute vs. Chronic Conditions
Standard private medical insurance in the UK is designed to cover acute conditions. An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Think of conditions like a hernia, cataracts, or a broken bone.
PMI does not cover chronic conditions. A chronic condition is one that is long-lasting and cannot be fully cured, such as diabetes, asthma, or indeed, osteoarthritis. Insurers do not cover the day-to-day management, monitoring, or medication for these conditions.
"So," you might ask, "if my knee pain is caused by osteoarthritis, which is chronic, how can my surgery be covered?"
This is a crucial distinction. While osteoarthritis is chronic, the surgery to replace the joint is considered a one-off intervention to resolve the acute symptoms (severe pain and loss of mobility). Insurers view the knee replacement as a definitive treatment to return you to your previous state of health, thus fitting the definition of acute care.
The Pre-Existing Condition Clause
All PMI policies have rules about pre-existing conditions. A condition is usually considered 'pre-existing' if you have had symptoms, received medication, or sought advice for it in the five years before your policy started.
If your knee problems began before you took out your health insurance, they will be excluded from cover. You cannot buy a policy to treat a problem you already have. Insurance is for future, unforeseen medical needs.
There are two main ways insurers handle this, known as 'underwriting':
-
Moratorium Underwriting: This is the most common type. The insurer automatically excludes any condition you've had in the 5 years before your policy start date. However, if you then go for a continuous 2-year period after your policy begins without having any symptoms, treatment, or advice for that condition, the exclusion may be lifted.
- Example: You had knee pain in 2023. You take out a policy in January 2025. Your knee is excluded. If you then have no knee pain, physio, or GP visits for your knee until February 2027, it may become eligible for cover from that point onwards.
-
Full Medical Underwriting (FMU): You complete a detailed health questionnaire when you apply. The insurer assesses your medical history and tells you upfront exactly what is and isn't covered. Any pre-existing knee conditions would be explicitly excluded in writing from day one. This provides certainty but can be more complex to set up.
An expert PMI broker like WeCovr can explain these options in detail and help you choose the underwriting method that best suits your circumstances.
How to Get Your Knee Surgery Covered: A Step-by-Step Guide
If you have a PMI policy and develop knee problems after your cover has started, here is the typical process for getting your treatment approved.
-
See Your GP: Your journey always starts with your GP. Whether you use your NHS GP or a private GP service (often included with PMI), you need a referral to a specialist. Describe your symptoms clearly.
-
Check Your Policy: Before your GP makes a referral, it's wise to check your policy documents. Look for:
- Outpatient Limit (illustrative): This is the amount your policy will pay for consultations and diagnostic tests before you are admitted to hospital. Make sure it's sufficient to cover a consultation and an MRI scan (which can cost £400-£700).
- Hospital List: Insurers have different tiers of hospital lists. Ensure the consultant and hospital you want to use are on your list.
- Excess (illustrative): This is the amount you have to pay towards a claim. A typical excess is between £100 and £500.
-
Get Pre-Authorisation for a Consultation: Contact your insurer and tell them your GP is referring you to a specialist for knee pain. They will give you a pre-authorisation number. You can then book an appointment with a consultant orthopaedic surgeon from their approved list.
-
The Specialist Consultation and Diagnosis: The consultant will examine you and likely order diagnostic tests like an X-ray or MRI scan to confirm the extent of the joint damage. Your insurer will need to pre-authorise these scans.
-
The Treatment Plan and Final Authorisation: If the consultant confirms that a knee replacement is the most appropriate treatment, their secretary will put together a treatment plan. This includes the procedure code for the surgery, the anaesthetist's fees, and the hospital costs. This package is sent to your insurer for final approval.
-
Approval and Booking: Once the insurer provides a final pre-authorisation number for the surgery, you are clear to book your operation. The hospital will handle all the direct billing with your insurer.
-
Surgery and Recovery: You have your surgery in your chosen private hospital. After the operation, your insurance will also typically cover your post-operative physiotherapy sessions, which are vital for a successful recovery. You only need to pay the excess you chose when you took out your policy.
Choosing the Right Private Health Insurance for Future Orthopaedic Needs
If you don't have cover yet but are concerned about future joint health, it's wise to choose a policy with strong orthopaedic benefits. Here’s what to look for:
- Comprehensive Outpatient Cover (illustrative): Opt for a higher limit (£1,000+) or an unlimited option. This ensures you're covered for all the consultations and scans needed for a swift diagnosis.
- A Good Hospital List: A 'nationwide' list gives you an excellent choice of hospitals across the UK. If you live in or near London, check if the policy includes a 'London hospital' option, as these can sometimes be on a separate, more expensive tier.
- Full Cover for Therapies: Ensure physiotherapy, and sometimes osteopathy or chiropractic care, is included. Check the number of sessions covered, as you may need quite a few after a knee replacement.
- Guided Care Pathways: Some of the best PMI providers offer 'guided' options. This is where the insurer helps you choose from a smaller, curated list of high-performing consultants. This can reduce your premium without sacrificing quality.

How Much Does a Private Knee Replacement Cost in the UK?
If you were to pay for the surgery yourself (self-funding), the costs can be substantial. Understanding these costs helps to demonstrate the value of a comprehensive private health cover policy.
As of 2025, the all-inclusive 'package price' for a private knee replacement in the UK typically ranges from £13,500 to £18,000. (illustrative estimate)
Here's a breakdown of what that price usually includes:
| Component | Estimated Cost (if billed separately) | Covered by PMI? |
|---|---|---|
| Initial Consultant Appointment | £200 - £300 | Yes (from outpatient limit) |
| MRI Scan | £400 - £700 | Yes (from outpatient limit) |
| Surgeon's & Anaesthetist's Fees | £3,000 - £5,000 | Yes (fully covered) |
| Hospital Costs (2-3 nights) | £7,000 - £9,000 | Yes (fully covered) |
| Knee Prosthesis | £1,500 - £2,500 | Yes (fully covered as part of surgery) |
| Post-op Physiotherapy (6 sessions) | £300 - £450 | Yes (from therapies limit) |
| Total (Approximate) | £12,400 - £18,000+ | Yes, all covered except your excess |
For a monthly premium, PMI protects you from having to find this significant sum yourself, providing peace of mind and rapid access to care when you need it most.
Life After Knee Replacement: Recovery, Wellness, and Staying Active
Your health journey doesn't end when you leave the hospital. A successful outcome depends heavily on your commitment to recovery.
- Recovery Timeline: You'll be up and walking (with support) within a day of surgery. You'll likely be home in 2-3 days. Most people are back to light activities in 6 weeks and can expect to feel close to normal within 3-6 months. Full recovery can take up to a year.
- Physiotherapy is Non-Negotiable: Diligently follow the exercise plan given to you by your physiotherapist. This is crucial for regaining strength, flexibility, and a natural gait.
- Diet and Weight Management: Maintaining a healthy weight is the single best thing you can do for your new knee. Every extra pound of body weight puts 4-6 pounds of extra pressure on your knee joints. A balanced diet rich in protein, calcium, and Vitamin D will aid healing.
- WeCovr's CalorieHero App: As a WeCovr customer, you get complimentary access to our AI-powered calorie and nutrition tracking app, CalorieHero. It's a fantastic tool to help you manage your weight and support your long-term joint health.
- Return to Activity: Once cleared by your surgeon, low-impact activities like swimming, cycling, golf, and walking are excellent for maintaining fitness without stressing the new joint.
