A pre-existing knee condition does not block private physiotherapy access in the UK. Insurance may cover it, exclude it, or impose a 2-year waiting period. Self-pay always works. Our team at One Body LDN treats patients with chronic knee osteoarthritis, old ACL reconstructions, longstanding meniscus tears, and recurring patellofemoral pain across London every day. The five steps below show you how to access private knee physiotherapy with a pre-existing condition.
Key takeaways
- A pre-existing knee condition is any knee problem you had symptoms, treatment, or medical advice for in the 5 years before your insurance policy started
- UK private health insurers handle pre-existing conditions through full medical underwriting or moratorium underwriting (2 continuous treatment-free years required)
- Self-pay is the reliable route for most pre-existing knee conditions, with no underwriting, no exclusions, and no waiting periods
- A private knee physiotherapy initial assessment in the UK typically costs £60 to £150, with follow-ups £55 to £95
- No GP referral is needed. We accept self-referrals across our London clinics with same-week availability
Step 1: What counts as a pre-existing knee condition
A pre-existing knee condition is any knee problem you had symptoms, treatment, tests, medication, or medical advice for in the five years before your private health insurance policy started.
How UK insurers define a pre-existing knee condition
UK insurers use a 5-year lookback from your policy start date. Symptoms, medication, advice, treatment, or tests during that window all count, even for an undiagnosed knee problem. The definition applies to any disease, illness, or injury affecting the knee.
Common pre-existing knee conditions we treat at One Body LDN
The most common knee conditions we treat under pre-existing rules include:
- Knee osteoarthritis and chronic wear and tear
- Previous ACL reconstruction or ligament repair
- Old meniscus tear, treated or untreated
- Recurring runner’s knee and patellofemoral pain syndrome
- Chronic knee instability
- Post-surgical knee rehabilitation, including knee replacement and arthroscopy recovery
Step 2: How private health insurance handles pre-existing knee conditions
UK private health insurers handle pre-existing knee conditions through two underwriting systems: full medical underwriting and moratorium underwriting.
Full medical underwriting
Full medical underwriting requires you to declare your knee condition when applying. The insurer reviews your medical history, may contact your GP, and decides one of three outcomes: cover the condition normally, exclude the knee condition permanently, or charge a higher premium to include it. AXA, Aviva, and Bupa each offer full medical underwriting as a policy option.
Moratorium underwriting
Moratorium underwriting requires no upfront disclosure. Each claim is reviewed against your medical records at the point of claiming. A pre-existing knee condition becomes covered only after 2 continuous treatment-free years from your policy start date. “Treatment-free” means no symptoms, medication, tests, advice, or treatment for the knee condition during the 2-year window. Vitality uses moratorium underwriting as standard, and Aviva offers it as an option.
Most pre-existing knee conditions managed in the last 2 years face exclusion or waiting periods under either underwriting type.
Step 3: Self-pay is the reliable route
Self-pay is the reliable route to private physiotherapy for most pre-existing knee conditions because the route bypasses insurance underwriting, exclusions, and waiting periods entirely.
Why self-pay always works
Self-pay delivers what insurance often cannot for pre-existing knee conditions:
- No medical underwriting required
- No 2-year treatment-free waiting period
- No risk of claim rejection or pre-existing exclusion
- No pre-authorisation paperwork or insurer phone calls
- Same-week assessment availability
- Direct continuity with the same physiotherapist throughout treatment
Insurance often makes economic sense for new injuries. Self-pay makes sense for pre-existing knee conditions, where insurance cover is conditional at best and excluded at worst. Our team at One Body LDN welcomes self-paying patients with same-week appointments across our central London clinics, all led by HCPC-registered and MCSP-chartered clinicians.
Typical UK self-pay costs
The cost of private knee physiotherapy in the UK is consistent across reputable clinics:
- Initial assessment: £60 to £150 (London clinics sit at the higher end)
- Follow-up session: £55 to £95
- Block packages available for chronic and post-surgical conditions
Most patients recover the assessment cost within the first two sessions of structured rehabilitation.
Step 4: When to use insurance vs self-pay
The choice between insurance and self-pay depends on three factors: your underwriting type, how recently the knee condition was treated, and how urgently you need care.
Self-pay makes sense if:
- Your knee condition was treated in the last 2 years
- Your policy excludes the knee condition under full medical underwriting
- You need same-week treatment without pre-authorisation
- Your policy excludes physiotherapy entirely
Insurance makes sense if:
- Your knee condition has been treatment-free for 2+ years under moratorium underwriting
- Your policy covers physiotherapy without pre-existing exclusion
- You hold a chronic condition cover rider
- You can wait through pre-authorisation timelines
Step 5: Book your knee physiotherapy assessment
Booking a private knee physiotherapy assessment with a pre-existing condition follows the same self-referral route as a new patient.
What to bring
Bring previous knee imaging or scan reports, prior physiotherapy or surgical notes, a current medications list, and any insurance pre-authorisation code if using insurance.

Common questions about private physiotherapy with pre-existing conditions
These four questions are the most common ones we hear from patients with a pre-existing knee condition.
Can I get private health insurance with a pre-existing knee condition?
Yes, you can take out private health insurance with a pre-existing knee condition, but the condition itself may not be covered. Full medical underwriting may exclude the knee condition or charge a higher premium. Moratorium underwriting may cover it after 2 continuous treatment-free years. Self-pay always works without conditions.
Do Bupa, AXA, and Vitality accept pre-existing knee conditions?
Bupa, AXA, and Vitality accept customers with pre-existing knee conditions, but apply underwriting rules that may exclude the specific condition from cover. Bupa and AXA offer both full medical and moratorium options. Vitality uses moratorium underwriting with the 2-year rule.
Is it worth paying for private physio with a pre-existing knee condition?
Yes, private physiotherapy is worth paying for with a pre-existing knee condition because most insurance policies exclude it or impose multi-year waiting periods. Self-pay delivers same-week access, continuity with one physiotherapist, and structured rehabilitation from £55 per follow-up session.
What is the 80/20 rule for chronic knee conditions?
The 80/20 rule means roughly 80% of recovery from a chronic knee condition comes from the exercises you do at home between sessions, and 20% comes from in-clinic treatment. Long-standing knee conditions need consistent home work more than acute injuries do.
Note: When pre-existing knee conditions need GP review first
Some knee conditions need GP review before private physiotherapy:
- Suspected rheumatoid or inflammatory arthritis
- Undiagnosed knee swelling with fever or systemic symptoms
- Severe new pain on top of the pre-existing condition
- Sudden new locking, instability, or knee deformity
Contact your GP or NHS 111 for assessment in these cases.
