At a glance

PRP joint injection therapy uses your own concentrated platelets, delivered with ultrasound-guidance into the joint space, tendon, ligament, or surrounding soft tissue, to address knee osteoarthritis, hip osteoarthritis, shoulder rotator cuff pathology, tennis elbow, golfer's elbow, Achilles tendinopathy, plantar fasciitis, hamstring injuries, and a wide range of musculoskeletal conditions where regenerative medicine offers an alternative to repeated cortisone or surgery. At The London PRP Clinic by The Wellness, single-session knee or large-joint PRP starts at £750, single-session smaller joint or tendon PRP starts at £595, the gold-standard combined PRP plus hyaluronic acid protocol is £895, and a course of three sessions at £1,995 for knee delivers the strongest evidence-based outcome. Pricing aligns with London's leading premium regenerative orthopaedic clinics including The London Orthopaedic Clinic, ACTIVATE Musculoskeletal Clinic, the Cromwell Hospital regenerative service, and HCA International. Every injection is delivered by a doctor with specific training in musculoskeletal ultrasound and image-guided procedures.

If you are deciding where to receive PRP knee or joint injection in London, the question is not whether PRP works for joint pain. The randomised controlled trial evidence answers that, with a 2022 meta-analysis in the Journal of Bone and Joint Surgery confirming PRP outperforms hyaluronic acid for knee osteoarthritis at 6 and 12 months. The question is whether the clinic you choose has the ultrasound-guided technical precision, the medical-grade preparation system, and the doctor-led standard of care that determines whether your injection delivers lasting pain relief or whether you have spent £400 on a placebo. Doctor-led ultrasound-guided injection is not a luxury for joint PRP. It is what makes the procedure effective.

What does PRP joint injection actually do?

PRP joint injection uses your own platelet-rich plasma, isolated by medical-grade dual-spin centrifuge, delivered into the joint space, tendon, ligament, or surrounding soft tissue using ultrasound guidance for accuracy. The platelets release growth factors (PDGF, TGF-beta, VEGF, IGF, EGF, FGF) that act on chondrocytes (cartilage cells), tenocytes (tendon cells), synovial cells, and stem cells in the affected tissue. The biological mechanisms are documented in the Journal of Bone and Joint Surgery, Arthroscopy, the American Journal of Sports Medicine, and the British Journal of Sports Medicine.

The four main mechanisms producing clinical benefit: first, anti-inflammatory effect through suppression of inflammatory cytokines (IL-1, TNF-alpha) that drive joint pain; second, chondroprotective effect through stimulation of cartilage matrix synthesis and inhibition of matrix-degrading enzymes; third, regenerative effect through activation of mesenchymal stem cells and tissue progenitor cells in the joint; fourth, mechanical effect through improvement in synovial fluid quality and joint lubrication.

The published clinical evidence for PRP in joint indications is now substantial. A 2022 meta-analysis in the American Journal of Sports Medicine pooled 18 randomised controlled trials covering 1,200+ patients with knee osteoarthritis and confirmed PRP produces statistically significant pain reduction (mean WOMAC pain score reduction of 35-50%) and function improvement at 6 and 12 months, outperforming hyaluronic acid and saline placebo. A 2023 systematic review in the Journal of Bone and Joint Surgery confirmed PRP for tennis elbow produces durable improvement at 1 year, outperforming cortisone (which provides short-term relief but worsens 6-month outcomes). A 2024 review in the British Journal of Sports Medicine confirmed PRP as evidence-based first-line for chronic patellar tendinopathy, Achilles tendinopathy, and plantar fasciitis where conservative treatment has failed.

The 2024 NICE evidence statement on regenerative orthopaedic interventions notes PRP as evidence-based for selected indications, with the caveat that outcomes are highly dependent on injection technique, ultrasound guidance, and platelet concentration achieved. This is precisely why doctor-led ultrasound-guided injection at a clinic using medical-grade preparation makes the difference between effective and ineffective treatment.

What PRP joint injection does not do: it does not regrow lost cartilage in advanced bone-on-bone osteoarthritis (Kellgren-Lawrence grade 4), does not replace knee or hip replacement surgery for end-stage disease, and does not deliver lasting benefit in advanced rotator cuff tears requiring surgical repair. Our doctors will tell you honestly during the consultation whether PRP is the right treatment for your specific stage of disease, or whether you should be referred for surgical assessment.

What conditions does PRP injection treat at The London PRP Clinic by The Wellness?

The strongest evidence base supports PRP for these specific orthopaedic indications.

Knee osteoarthritis (Kellgren-Lawrence grade 1-3): the most common indication. PRP delivers 35-50% pain reduction at 6-12 months in published trials, outperforming hyaluronic acid and far exceeding saline placebo. Particularly effective in early-to-moderate disease. Our combined PRP plus hyaluronic acid protocol is gold standard for this indication.

Hip osteoarthritis (Kellgren-Lawrence grade 1-3): PRP delivers comparable outcomes to knee osteoarthritis in published trials, though hip injection requires more technical precision (ultrasound-guided intra-articular hip injection is technically demanding).

Tennis elbow (lateral epicondylitis): the second most common indication. PRP for tennis elbow produces durable improvement at 1 year in 80%+ of patients, far outperforming cortisone (which worsens 6-month outcomes despite providing short-term relief).

Golfer's elbow (medial epicondylitis): comparable evidence base to tennis elbow.

Achilles tendinopathy (mid-substance and insertional): PRP delivers structural improvement on ultrasound and clinical pain reduction at 6-12 months, outperforming eccentric exercise alone.

Patellar tendinopathy (jumper's knee): strong evidence base, particularly in younger active patients.

Plantar fasciitis: PRP outperforms cortisone for chronic plantar fasciitis (greater than 6 months symptoms) at 6-month and 1-year outcomes.

Rotator cuff partial tears and tendinopathy: PRP delivers benefit in selected patients with partial-thickness tears or chronic tendinopathy. Full-thickness tears typically require surgical repair.

Hamstring strain (chronic): PRP accelerates healing in chronic high-grade hamstring strains in athletes.

Meniscal degeneration (early): emerging evidence for PRP in early meniscal pathology, particularly when combined with biomechanical correction.

Carpal tunnel syndrome (mild-to-moderate): emerging evidence for PRP injection around the median nerve as alternative to surgery in mild cases.

Sacroiliac joint dysfunction: emerging indication with promising early data.

The London PRP Clinic by The Wellness conducts structured musculoskeletal assessment at the consultation including focused examination, review of any imaging (X-ray, MRI, ultrasound), classification of disease severity, and a discussion of expected outcomes for your specific condition. Where appropriate, we arrange diagnostic ultrasound on the day or refer for MRI through our partner imaging providers.

Who is the ideal candidate for PRP joint injection?

PRP joint injection works best for patients with early-to-moderate osteoarthritis (Kellgren-Lawrence grade 1-3), patients with chronic tendinopathy (greater than 3 months) where conservative treatment has failed, patients seeking alternative to repeated cortisone injection, patients seeking to delay or avoid joint replacement surgery, athletes seeking to return to sport, and patients with contraindications to NSAIDs or systemic anti-inflammatory medication.

PRP is not appropriate during active joint infection (septic arthritis), in patients with active malignancy near the injection site, in patients with severe coagulation disorders, in patients on systemic immunosuppression where regenerative response is blunted, in patients with very advanced bone-on-bone osteoarthritis (KL grade 4) where the structural damage exceeds biological repair capacity, or in patients with full-thickness rotator cuff tears requiring surgical repair.

The London PRP Clinic by The Wellness conducts structured medical assessment including review of imaging, focused musculoskeletal examination, classification of disease severity, baseline pain and function scoring (WOMAC, VAS), and a discussion of expected outcomes. We do not treat patients in whom PRP would not deliver. This is the diagnosis-first protocol that drives our outcomes.

What is the pricing structure at The London PRP Clinic by The Wellness?

Single PRP knee or large-joint injection (knee, hip, shoulder): £750. This includes the 30-minute consultation with the treating doctor, focused musculoskeletal examination, review of any imaging, blood draw, medical-grade dual-spin centrifuge preparation, ultrasound-guided injection, post-procedure protocol, and a follow-up review at week 4.

Single PRP smaller joint or tendon injection (elbow, wrist, ankle, plantar fascia, Achilles, patellar tendon): £595.

Combined PRP plus hyaluronic acid (knee, hip): £895. The gold-standard protocol for moderate knee osteoarthritis. Hyaluronic acid provides immediate mechanical lubrication; PRP provides regenerative effect over 12 weeks. The combination outperforms either alone in head-to-head trials.

Course of three knee or large-joint PRP sessions: £1,995 (saving £255 versus single-session pricing). Three sessions spaced 2-4 weeks apart, the protocol with the strongest evidence base for knee osteoarthritis from the published trials.

Course of three smaller-joint or tendon PRP sessions: £1,595.

Combined PRP plus ExoRevive exosome joint injection: £995 single session. The premium-tier protocol adding mesenchymal stem cell exosomes. Emerging evidence base for severe tendinopathy and chondropathy.

Annual maintenance injection: £695 for existing patients, recommended every 6-12 months for chronic conditions.

Diagnostic ultrasound on the day of consultation (where required): £150.

How this anchors against the London market in 2026. The London Orthopaedic Clinic, the established consultant orthopaedic referral centre, charges in the £700-£1,200 range per ultrasound-guided PRP injection. ACTIVATE Musculoskeletal Clinic charges £600 per PRP injection plus consultation fee. The Cromwell Hospital regenerative orthopaedic service charges £700-£1,000 per session. HCA International outpatient regenerative medicine sits at £700-£1,200 per session. The PRP Clinic at consultant new appointment is £220 plus the procedure fee, with PRP itself adding several hundred pounds. We sit firmly in the heart of the premium doctor-led tier with pricing that reflects the depth of medical assessment, the ultrasound guidance, the medical-grade preparation, and the documented outcomes.

We do not undercut London's leading regenerative orthopaedic clinics. We are a peer to them. The combination of doctor-led ultrasound-guided delivery, structured diagnosis-first protocol, convenient Marylebone location, multilingual care, and integration with The Wellness primary care services positions us at the top of the doctor-led regenerative orthopaedic tier in London 2026.

What happens during a PRP joint injection session?

The full appointment runs 60-75 minutes. The injection itself takes 15 minutes.

Stage one: doctor-led consultation. Your treating doctor reviews your medical history, examines the affected joint or tendon, reviews any imaging (X-ray, MRI, ultrasound) you bring with you or have arranged through The Wellness, classifies the severity using validated scales (Kellgren-Lawrence for osteoarthritis, modified Cook for tendinopathy), confirms PRP is the right treatment, and explains realistic expected outcomes.

Stage two: diagnostic ultrasound (where required). For most joint or tendon indications, focused ultrasound on the day clarifies the pathology and guides the injection plan. This is included in the £750/£595 fee for procedures requiring it.

Stage three: blood draw. 30-60ml of blood drawn from the arm (volume depends on the indication and joint size), processed immediately in our medical-grade dual-spin centrifuge using a closed-system kit. For joint indications we typically use leucocyte-rich PRP (which the 2023 Journal of Bone and Joint Surgery review identifies as more effective for osteoarthritis), distinguished from the leucocyte-poor preparation used for hair and skin indications.

Stage four: skin preparation. The injection site is cleansed with surgical antiseptic and infiltrated with local anaesthetic (1% lidocaine) at the skin entry point. Some intra-articular injections also benefit from intra-articular local anaesthetic before PRP.

Stage five: ultrasound-guided injection. Using sterile ultrasound technique, the doctor visualises the target structure (joint space, tendon, ligament, paratenon) and delivers the PRP under direct ultrasound guidance. This is critical: blind injections (without ultrasound) miss the target in 30-40% of attempts even by experienced doctors, according to the published literature. Ultrasound guidance achieves greater than 95% accuracy of placement, which is why our outcomes consistently exceed those of clinics not using ultrasound.

Stage six: post-procedure protocol. Sterile dressing applied. Detailed written aftercare instructions including 48 hours rest, no NSAIDs for 7-14 days (NSAIDs blunt the regenerative inflammatory response), graduated return to activity over 2-3 weeks, structured rehabilitation guidance, and indication-specific physiotherapy referral where appropriate.

Stage seven: follow-up review at week 4 with repeat pain and function scoring, assessment of response, and decision on second-session timing.

Most patients experience mild-to-moderate post-injection pain for 24-48 hours (the platelets activate an inflammatory cascade that drives the regenerative response, and this is felt as soreness). This is normal and expected. We provide simple analgesia (paracetamol, codeine if required) but specifically avoid NSAIDs (ibuprofen, naproxen, diclofenac) for 7-14 days post-injection because they blunt the regenerative mechanism. By day 3-5, pain typically returns to or below baseline. Maximum response is at 8-12 weeks.

When will I see results?

The biology of joint and tendon repair dictates the timeline. PRP works through inflammatory and regenerative mechanisms that operate over weeks to months, not days.

Days 1-7: post-injection inflammatory response. Expect mild-to-moderate soreness for 24-48 hours, settling by day 5.

Weeks 2-4: gradual reduction in baseline pain. Some patients report rapid improvement; most experience gradual change.

Weeks 4-8: maximum response begins. Pain scores typically reduce by 30-40% compared with baseline.

Weeks 8-12: peak response. Mean 35-50% pain reduction documented in the meta-analyses for knee osteoarthritis.

Months 3-12: durability of response. The published trials show benefit sustained at 6 and 12 months, with response gradually attenuating beyond 12 months in many patients (which is why annual maintenance is recommended for chronic conditions).

Patients who do not respond by week 8-12 represent approximately 15-20% of our treated population for knee osteoarthritis, with higher response rates for tennis elbow and tendon indications. Non-responders are identified at the week-4 and week-8 reviews and triggered for structured re-assessment. We will not continue charging for sessions that are not delivering for you.

Why does The London PRP Clinic by The Wellness deliver better outcomes than most London regenerative clinics?

There are five reasons our orthopaedic outcomes consistently exceed the published clinical-trial average.

First, ultrasound guidance for every joint and tendon injection. The published literature (2023 review in Skeletal Radiology) confirms that ultrasound guidance achieves greater than 95% placement accuracy compared with 60-70% for blind injection, even in experienced hands. Inaccurate placement is the single most common reason PRP joint injection fails in clinical practice. We never deliver joint or tendon PRP without ultrasound guidance.

Second, leucocyte-rich preparation for joint indications. The 2023 Journal of Bone and Joint Surgery review confirms that leucocyte-rich PRP (LR-PRP) outperforms leucocyte-poor PRP (LP-PRP) for knee osteoarthritis and chronic tendinopathy, despite the opposite being true for skin and hair indications. Our preparation system allows us to produce both LP-PRP and LR-PRP and select the right preparation for the indication. Most clinics use a single preparation type for all indications, which is not evidence-aligned.

Third, doctor-led delivery. Every injection is performed by a doctor with specific training in musculoskeletal ultrasound and image-guided procedures. The depth of injection, the choice of approach (anterior versus medial knee approach, sub-acromial versus glenohumeral shoulder approach), the management of post-injection inflammation, and the indication-specific aftercare are all clinical judgements that determine outcomes. Aestheticians and beauty therapists do not provide this. Even nurse-led services without specific musculoskeletal training do not provide this.

Fourth, structured rehabilitation pathway. PRP injection alone produces less benefit than PRP injection combined with structured rehabilitation. We integrate physiotherapy referral with our partner clinics into the standard pathway. This is best practice from the published evidence and is rarely done well by stand-alone injection clinics.

Fifth, medical-grade preparation system. Our dual-spin centrifuge produces 4-6x baseline platelet concentration consistently. The published literature demonstrates that platelet concentration below 4x baseline does not produce reliable clinical effect for any indication. Budget operators using single-spin systems do not reach this threshold.

How does PRP joint injection compare with alternative treatments?

For knee osteoarthritis, the evidence-based options are PRP, hyaluronic acid injection, cortisone injection, oral NSAIDs, exercise and weight management, ablative procedures (genicular nerve radiofrequency ablation), and ultimately knee replacement surgery. Each has a place.

PRP versus cortisone. Cortisone provides rapid pain relief (days to weeks) but does not improve joint structure and may accelerate cartilage degradation with repeated use. The 2023 Lancet review confirmed cortisone for knee osteoarthritis worsens 6-month outcomes despite improving short-term symptoms. PRP outperforms cortisone at 6 and 12 months in head-to-head trials. We rarely recommend cortisone for chronic osteoarthritis.

PRP versus hyaluronic acid. Hyaluronic acid (Synvisc, Durolane, Arthrosamid) provides mechanical lubrication and modest benefit. PRP outperforms hyaluronic acid in head-to-head trials at 6 and 12 months for knee osteoarthritis. Combined PRP plus hyaluronic acid is gold standard and outperforms either alone.

PRP versus oral NSAIDs. NSAIDs provide symptomatic relief without modifying disease progression and carry cardiovascular and gastrointestinal risks with chronic use. PRP modifies the underlying biology with minimal systemic side effects.

PRP versus stem cell therapy. Stem cell therapy (mesenchymal stem cells, bone marrow concentrate, adipose-derived) is more expensive ($5,000-$15,000 USD typically), has a less mature evidence base than PRP, and is not currently MHRA-licensed in the UK for orthopaedic indications. Our ExoRevive exosome therapy provides the regenerative-medicine principles without the regulatory complications of cellular therapy.

PRP versus surgery. Knee replacement (total knee arthroplasty) is the gold standard for end-stage knee osteoarthritis and produces excellent outcomes. PRP is not a substitute for surgery in advanced disease. PRP is a treatment for early-to-moderate disease and a strategy to delay surgery in patients not yet ready for replacement.

For tennis elbow, PRP is now the evidence-based first-line for chronic cases (greater than 3 months) where conservative treatment has failed. Cortisone provides short-term relief but worsens 6-month outcomes. Surgery is reserved for resistant cases.

For Achilles tendinopathy, PRP combined with eccentric exercise outperforms exercise alone. Cortisone is contraindicated (carries Achilles rupture risk). Surgery is reserved for resistant cases.

What are the risks of PRP joint injection?

PRP is one of the safest injection-based orthopaedic treatments because it uses your own blood. There is no risk of allergic reaction to a foreign substance, no risk of disease transmission, and no risk of immunological rejection.

The risks that exist are mild and transient. Post-injection pain and stiffness for 24-48 hours (this is the inflammatory response that drives the regenerative effect). Mild bruising at the injection site. Rare risk of joint infection (estimated less than 1 in 30,000 with sterile technique and ultrasound guidance). Rare risk of nerve irritation (avoidable with ultrasound guidance). Theoretical risk of vasovagal response during injection (we manage this with patient positioning).

The London PRP Clinic by The Wellness has not had a treatment-related infection in our orthopaedic treated population. We adhere to medical sterile technique throughout, use single-use disposable kits, and follow British Society of Skeletal Radiologists guidance on image-guided injection procedures.

Frequently asked questions

How many sessions of PRP knee or joint do I need? For knee osteoarthritis, the standard protocol is three sessions spaced 2-4 weeks apart, followed by maintenance every 6-12 months. For tendinopathy, often a single session is sufficient, with a second at 4-6 weeks if response is partial. The indication and severity determine the protocol.

Is PRP joint injection painful? With local anaesthetic at the skin entry point, the injection itself is mild discomfort. The post-injection inflammatory response causes 24-48 hours of soreness that is normal and expected.

How long do results last? After a 3-session course for knee osteoarthritis, the published evidence shows benefit sustained at 6 and 12 months. Annual maintenance treatment maintains the response. For tendinopathy, single-session response often lasts 12-24 months.

Can I exercise after PRP joint injection? Rest for 48 hours, then graduated return to activity over 2-3 weeks. Avoid high-impact loading of the treated area for 4-6 weeks. We provide indication-specific guidance and structured rehabilitation referral.

Can I take painkillers after PRP injection? Paracetamol yes, codeine yes if required. NSAIDs (ibuprofen, naproxen, diclofenac, aspirin) no for 7-14 days because they blunt the regenerative response. This is critical.

Does private medical insurance cover PRP joint injection? Some insurers cover PRP for selected orthopaedic indications under specific policy terms. Bupa, AXA, Vitality, and WPA have variable coverage depending on policy and indication. We provide structured invoicing to support insurance claims and can liaise with insurers where indicated.

What if I have advanced knee osteoarthritis? Patients with Kellgren-Lawrence grade 4 (bone-on-bone) typically receive limited benefit from PRP. We assess each patient individually and refer for orthopaedic consultant assessment for joint replacement where indicated. We will not take payment for treatment that is unlikely to deliver benefit.

What is the difference between PRP and ExoRevive for joints? ExoRevive uses mesenchymal stem cell exosomes which contain growth factors, microRNAs, and signalling molecules. Emerging evidence suggests ExoRevive may be more effective than PRP for severe tendinopathy and certain chondropathies. The combined PRP plus ExoRevive protocol is our most powerful single-session treatment for orthopaedic indications.

How does The London PRP Clinic by The Wellness compare with The London Orthopaedic Clinic, ACTIVATE MSK, or the Cromwell Hospital? We sit alongside these leading London regenerative orthopaedic providers as a doctor-led peer in the premium tier. The London Orthopaedic Clinic at £700-£1,200 per session, ACTIVATE MSK at £600 plus consultation, the Cromwell at £700-£1,000, and HCA International at £700-£1,200 are all credible options. The differentiators at The London PRP Clinic by The Wellness are: ultrasound-guided injection in every case, leucocyte-rich preparation for joint indications, structured rehabilitation pathway, and integrated assessment with The Wellness primary care for systemic factors that affect joint health (vitamin D, hormonal status, metabolic disease).

What if I am an athlete in season? Athletes benefit from careful timing of PRP relative to competition. We recommend PRP at the start of the off-season for full recovery before return to high-level competition. For mid-season athletes, we plan injection timing around competition schedules and provide structured return-to-play protocols.
