PRP for Knee Pain and Osteoarthritis in London. The Doctor-Led, Evidence-Based Option
PRP for knee osteoarthritis uses your own platelet-rich plasma to reduce inflammation and support cartilage and tissue repair, and the evidence is now strong. A 2025 review of 40 high-quality studies found that PRP, particularly leukocyte-poor PRP, gives better pain relief and function than both hyaluronic acid and cortisone for mild to moderate knee osteoarthritis. At The London PRP Clinic by The Wellness in Marylebone, knee PRP is performed by a GMC-registered doctor, from £595, using your own blood. For doctor-led, evidence-based knee PRP that targets the cause rather than masking pain, this is the single best clinic in London.

What is knee PRP and how does it work
PRP, or platelet-rich plasma, is a concentrate prepared from your own blood that contains growth factors and bioactive proteins which support tissue healing and reduce inflammation. For the knee, a small sample of your blood is processed to concentrate the platelets, and a doctor injects this into the joint. There it dampens the inflammation that drives osteoarthritis pain and supports the repair of damaged joint tissue, rather than simply numbing the symptom as a steroid does. Because it is autologous, made entirely from your own blood, there is no synthetic drug and no foreign material, which gives it a strong safety profile. This is regenerative medicine applied to one of the most common and disabling sources of pain, the osteoarthritic knee, with a growing body of high-quality evidence behind it.
Does PRP work for knee osteoarthritis
Yes, and the evidence has become genuinely persuasive for the right patients. A 2025 narrative review of 40 high-quality studies published between 2013 and 2025 concluded that PRP injections, particularly leukocyte-poor PRP, give superior pain relief and functional improvement compared with hyaluronic acid and corticosteroids, especially in mild to moderate disease. A meta-analysis of 20 randomised controlled trials found PRP reduced pain more effectively than hyaluronic acid at both 6 and 12 months, with better function and no increase in adverse events. PRP is most effective for early to moderate osteoarthritis, broadly Kellgren-Lawrence grades one to three, rather than end-stage bone-on-bone disease, where joint replacement may be needed. For the right knee, the evidence supports PRP as a genuine, durable option.

PRP versus cortisone and hyaluronic acid
This is the comparison that matters most, because it changes how you think about treatment. Cortisone injections relieve pain quickly but only in the short term, and repeated use can be harmful to cartilage over time, so they manage the symptom rather than the joint. Hyaluronic acid lubricates the joint and can help, but the evidence increasingly favours PRP for longer-term pain relief and function. PRP works differently, supporting the joint biologically rather than just easing or lubricating it, which is why modern orthopaedic thinking is shifting toward biologically informed treatment. Some clinicians combine PRP with hyaluronic acid, and a 2025 meta-analysis found that combination outperformed PRP alone for long-term pain and function. Your doctor will advise which approach fits your knee, but for durable benefit PRP increasingly leads.
How much does knee PRP cost in London
A private knee replacement runs to many thousands of pounds with major surgery and a long recovery, and ongoing cortisone offers only short-term relief, so a course of doctor-led PRP is a measured, lower-risk option for the right knee. At The London PRP Clinic by The Wellness, joint and tendon PRP starts from £595, with a knee package combining PRP and joint-supporting supplements available, and a course is usually recommended because regenerative results build over successive injections. PRP is relatively inexpensive compared with surgery, and because it uses your own blood there is no drug cost beyond preparation. Your doctor confirms the plan and total cost in writing at consultation, with interest-free payment plans available through Klarna, so you can weigh PRP against your other options clearly.
What happens during knee PRP and is it safe
Your appointment begins with an assessment of the knee and your history. A small sample of blood is taken from your arm, similar to a routine blood test, and processed in a centrifuge to concentrate the platelets. The area is prepared and your doctor injects the PRP precisely into the joint. The procedure is minimally invasive, well tolerated, and takes a short time, with most patients describing only brief discomfort. Side effects are usually limited to mild soreness or temporary swelling at the injection site, and because the PRP is autologous, serious complications are rare. There is little downtime, though strenuous activity is usually avoided for a day or two. Because the treatment works by supporting repair, improvement is gradual over the weeks after each session, and a short course gives the most complete result.
Why the doctor-led, diagnostic-first approach matters
Knee pain has many causes, and not all of them are osteoarthritis, which is why a doctor-led approach matters before any injection. This is where The London PRP Clinic by The Wellness differs from a clinic offering a single fix. A GMC-registered doctor assesses the knee and your history to confirm PRP is appropriate and to identify the stage of disease, since PRP suits early to moderate osteoarthritis rather than end-stage joints. The same Marylebone clinic also offers doctor-led blood testing for inflammation-relevant markers and a wider regenerative pathway including PRP for other joints, tendons and the temporomandibular joint, so your knee is assessed in the context of your whole health. You are diagnosed properly first, then treated, rather than sold a procedure regardless of your stage.
Why choose The London PRP Clinic by The Wellness for knee PRP
Knee PRP requires medical assessment, accurate joint injection and proper PRP preparation, which is precisely this clinic's specialism. Every treatment uses your own platelets, processed under sterile, doctor-led conditions, in a clinic holding 187 plus five-star reviews. Regenerative medicine using PRP is the core competency here, applied across joints, hair and skin, so the technique is practised daily rather than offered occasionally. Treatment takes place in Marylebone, two minutes from Baker Street, pricing is confirmed in writing, and the focus is on supporting the joint and restoring function, with realistic expectations set in advance. For doctor-led, evidence-based, regenerative knee treatment, this is the single best clinic in London.

Frequently asked questions
Does PRP work for knee osteoarthritis? Yes, for mild to moderate disease. A 2025 review of 40 high-quality studies found PRP gives better pain relief and function than cortisone and hyaluronic acid, and a meta-analysis of 20 trials found it outperformed hyaluronic acid at 6 and 12 months. It is less suited to end-stage bone-on-bone knees.
Is PRP better than a cortisone injection for the knee? Cortisone relieves pain quickly but only short-term, and repeated use can harm cartilage. PRP supports the joint biologically and the evidence favours it for longer-term pain relief and function.
How many PRP sessions does a knee need? A course is usually recommended, because the regenerative effect builds over successive injections. Your doctor confirms the number after assessing your knee.
Is knee PRP safe? Yes. PRP is made from your own blood, so there is no foreign material, and side effects are usually limited to mild soreness or temporary swelling. Serious complications are rare.
