PRP is not an established replacement for rheumatoid arthritis treatment. Rheumatoid arthritis is an inflammatory autoimmune disease; osteoarthritis is a different condition with a different evidence base. Before considering a joint injection, the priority is confirming the diagnosis and making sure any inflammatory arthritis is being treated appropriately.
For someone trying to keep working, travelling or exercising with painful joints, a convenient injection can sound appealing. The better investment is a plan that addresses the cause of the pain rather than postponing the treatment that protects the joint.
Can PRP treat rheumatoid arthritis?
Research is exploring the question, but the clinical evidence remains limited. A 2021 systematic review identified only eight relevant studies: most were laboratory or animal studies, and the human evidence included a small patient series. Encouraging biological findings do not establish that PRP prevents rheumatoid joint damage or provides a dependable alternative to standard care. [1]
A broader review published at the end of 2024 discusses PRP's potential across rheumatic diseases, while also noting variable responses, inconsistent preparation and the need for stronger trials. It should not be read as proof that a commercial PRP course is an established rheumatoid arthritis treatment. [2]
Not sure which type of arthritis you have? Contact The London PRP Clinic and explain your diagnosis and symptoms before asking about injections. If inflammatory arthritis is suspected, the appropriate next step may be a rheumatology assessment rather than PRP.
Why is the distinction from osteoarthritis important?
Rheumatoid arthritis involves immune-driven inflammation. It can affect multiple joints and other parts of the body. Disease-modifying antirheumatic drugs, often called DMARDs, are used to control the disease and reduce the risk of damage. Early treatment matters. Mayo Clinic's 2025 treatment guidance places these medicines and regular follow-up at the centre of care. [3]
Osteoarthritis involves a different pattern of joint disease. Some people with knee osteoarthritis may discuss PRP as a symptom-management option, but evidence for osteoarthritis cannot be transferred directly to rheumatoid arthritis.
A painful knee in a person with rheumatoid arthritis may reflect active inflammation, coexisting osteoarthritis, injury or another cause. The diagnosis should guide treatment. A positive rheumatoid-factor result alone does not tell an injection clinic which process is responsible for today's pain.
Which symptoms deserve a diagnostic review?
Persistent joint swelling, warmth, prolonged morning stiffness, symptoms affecting several joints and a changing pattern of function are reasons to seek clinical assessment. Blood tests and imaging may help, but they are interpreted alongside the history and examination. There is no single test that settles every early case. [3]
Do not wait for a cosmetic or routine PRP appointment if you have a suddenly hot, very swollen joint, fever, feel acutely unwell or cannot bear weight. These features can require urgent assessment, including consideration of infection. An elective injection is not the right first response.
If you already have a rheumatologist, tell them about new or worsening symptoms. The team needs to know whether the disease is active before a separate clinic makes a local treatment plan.
What does the PRP research actually measure?
Laboratory research can examine inflammatory signals or cell behaviour. Animal experiments can test a biological hypothesis. Small human studies may report pain scores or disease-activity measures. These are different levels of evidence, and none should be described as equivalent to large, well-controlled trials showing durable protection from joint damage. [1,2]
PRP is also not one standard product. Platelet concentration, white-cell content, preparation and injection protocols differ. Results from one preparation cannot automatically validate another.
Ask the clinician which study supports your exact indication, whether it studied people with your diagnosis and treatment background, and what the result means in absolute terms. If the answer is mainly a description of growth factors, it has not yet answered the clinical question.
Should I stop my rheumatoid arthritis medicines for PRP?
Do not stop DMARDs, biologic medicines, steroids, anticoagulants or other prescribed treatment on your own to fit an injection appointment. Any change needs coordination with the prescribing clinician. Stopping a medicine may create a different risk, including a flare or complications from abrupt withdrawal. [3]
Provide the complete medicine list and the dates of recent doses. Include infections, antibiotics, blood disorders and any history of difficult healing. Suitability depends on your overall clinical situation, not only whether your blood can be drawn.
If a clinic asks you to pause an essential medicine, ask who has agreed that plan and how the risk will be managed. A generic aftercare leaflet is not enough to settle a medication decision.
Could a person with rheumatoid arthritis ever discuss PRP for another problem?
Possibly, but the other diagnosis and the rheumatoid disease still need to be considered together. Someone with well-managed rheumatoid arthritis may also have a separate tendon problem or degenerative knee symptoms. That does not automatically make PRP appropriate or inappropriate.
A useful assessment explains which problem is being treated, whether inflammation is controlled, what the evidence is for that indication and whether the treating rheumatology team should be involved. If those answers are unclear, paying for a course is premature.
How should I think about cost and value?
A premium injection price does not make an uncertain indication more evidence-based. The London PRP Clinic's services page is a starting point for enquiries, not a personalised treatment recommendation or a rheumatoid arthritis package quote.
Ask for a written total, the reason for each proposed injection, any review fees and the plan if symptoms do not improve. Do not compare a rheumatoid assessment with a hair-treatment price or assume that more injections mean greater protection from damage.
For a busy professional, good value may be a clear diagnosis and the right specialist referral, even when the outcome is a decision not to inject. The cost of delaying effective disease control can be greater than the inconvenience of a proper assessment.
Common questions
Is rheumatoid arthritis just severe osteoarthritis? No. They are different conditions and require different management.
Does using my own blood make PRP risk-free? No. There are still procedure-related risks and uncertainties about benefit, and your wider health and medicines matter.
Can PRP replace methotrexate? Current evidence does not establish it as a replacement. Do not change treatment without your rheumatology team. [1-3]
What should I bring to a suitability discussion? Your confirmed diagnosis, recent clinic letters, imaging reports, medication list and a record of swelling, stiffness and functional limitations.
Ask the clinic which assessment is appropriate, or email team@thewellnesslondon.com. Please state that you have rheumatoid arthritis or that it is being investigated, rather than describing the enquiry only as joint pain.
Ask the team on WhatsApp, or call +44 20 3951 3429 to discuss the appropriate next step.
