PRP For Tennis Elbow In London. What The Randomised Evidence Actually Shows

Tennis elbow is the condition where the gap between what is offered and what the trials support is widest. Corticosteroid injection remains the commonest treatment given and performs worse than doing nothing at a year. A 2025 Level I meta-analysis of 26 randomised trials found PRP statistically and clinically superior to corticosteroid beyond 6 months. The order in which you try things matters more here than almost anywhere else in musculoskeletal medicine.

Key points

  • Lateral epicondylitis is a tendinopathy, a failed healing response in the common extensor origin, rather than an inflammatory condition, which is why anti-inflammatory treatment underperforms.

  • A 2025 Level I meta-analysis of 26 randomised trials found PRP statistically and clinically better than corticosteroid beyond 6 months.

  • Corticosteroid reliably relieves pain for a few weeks and is associated with worse outcomes and higher recurrence at 12 months than placebo or exercise.

  • Most cases settle with load management and progressive strengthening. PRP is for the ones that do not.

What tennis elbow actually is

Pain over the bony point on the outside of the elbow, worse gripping, lifting a kettle, shaking hands or turning a door handle. The structure involved is the common extensor origin, and in particular the extensor carpi radialis brevis tendon where it attaches to the lateral epicondyle.

The suffix in epicondylitis implies inflammation, and biopsy studies have consistently shown something else. The tissue shows disorganised collagen, increased ground substance and new blood vessel and nerve ingrowth, with inflammatory cells largely absent. It is a tendon that has failed to heal rather than a tendon that is inflamed, which is the whole argument against reaching for an anti-inflammatory first.

Most people who get it have never played tennis. It is an overuse condition of gripping and wrist extension, and it appears in tradespeople, desk workers, new parents and anyone who has recently changed what their hands do.

Who gets it and why it lingers

Peak incidence sits between 35 and 55. In women in their 40s and 50s it frequently arrives alongside other tendon problems, because oestrogen receptors are present in tendon and falling oestrogen is associated with the connective tissue changes that make tendinopathy more likely. Someone who develops a frozen shoulder, then a tennis elbow, then plantar fasciitis inside 3 years is usually not unlucky.

Diabetes and smoking both impair tendon healing and both predict a slower course.

What the evidence supports, in order

Load management and waiting

Tennis elbow has a strong natural history. A substantial majority of cases resolve within 12 months with load modification alone, and this is the honest starting point for anyone in the first few weeks.

Load modification means reducing the specific provocations rather than resting the arm. Change the grip size on tools and rackets, move gripping tasks to the other hand where possible, and stop the repeated wrist extension that triggers it.

Progressive strengthening

Eccentric and heavy slow resistance loading of the wrist extensors is the best-evidenced active treatment, and it is the intervention that changes the tendon rather than the symptoms. It is done with a light weight, a resistance bar or a band, slowly, several times a week, over months.

As with every tendinopathy, the guide is the morning after. Mild discomfort during loading is acceptable. Worse pain the next morning means the load was too high.

Corticosteroid injection, and why we generally advise against it

Steroid works quickly. At 4 to 6 weeks the pain is usually much better, which is why it stays popular with both patients and prescribers.

The problem appears later. Randomised evidence has repeatedly found that by 12 months the corticosteroid group does worse than placebo or physiotherapy, with higher recurrence rates. Steroid injected around a tendon can also leave it more vulnerable to tearing and can cause subcutaneous fat atrophy and skin depigmentation at the site, which is visible and permanent.

PRP

PRP is autologous, meaning it is made from your own blood. It is prepared by centrifuging a sample to concentrate platelets, which carry the growth factors involved in tissue repair, and injecting that concentrate into the tendon under ultrasound guidance.

The 2025 Level I meta-analysis of 26 randomised trials found PRP statistically and clinically better than corticosteroid beyond 6 months. The pattern across the literature is consistent. Steroid wins early, PRP wins late, and the crossover typically sits somewhere between 3 and 6 months. If your problem is a wedding in 3 weeks, that is a different conversation from a problem you have had for a year.

The honest caveats. PRP preparation is not standardised between clinics, which limits how well trials can be pooled. It is more painful than a steroid injection for the first few days, because the intended response is an inflammatory healing response. And it is not a substitute for the loading programme that follows it.

What treatment costs in London

Image-guided joint and tendon PRP at specialist central London clinics commonly costs from around £780 to £900 or more per injection including assessment, with a course frequently exceeding £2,000. Outside central London the range is roughly £250 to £500, where injections are often performed without image guidance.

PRP is not routinely commissioned by the NHS for tendon conditions and private insurance rarely covers it, so this is self-pay. Physiotherapy and corticosteroid injection are both available on the NHS.

Our care is doctor-led and priced below flagship central London rates, with the figure confirmed after your free suitability review.

The suitability review

Every enquiry begins with a free doctor-led suitability review rather than a booking. A GMC-registered doctor takes your history, examines the elbow, and scans it with ultrasound to confirm tendinopathy and exclude the alternatives, which matter here. Radial tunnel syndrome, referred pain from the neck, a partial tear and posterolateral elbow instability all present as lateral elbow pain and none responds to an injection into the tendon.

Then one of two answers. Approved, with the plan, the loading work that runs alongside and the cost before you commit. Or not approved, which for elbow pain of less than 3 months usually means load modification and a strengthening programme first, because the natural history is good and most people do not need us.

Frequently asked questions about tennis elbow

Does PRP work for tennis elbow?

A 2025 Level I meta-analysis of 26 randomised trials found PRP statistically and clinically better than corticosteroid beyond 6 months. The benefit appears late rather than immediately, so it suits persistent cases rather than new ones.

Is a steroid injection better for tennis elbow?

Only in the short term. Steroid usually relieves pain within weeks, and randomised evidence has repeatedly found worse outcomes and higher recurrence at 12 months than placebo or physiotherapy.

How long does tennis elbow take to get better on its own?

A substantial majority of cases settle within 12 months with load modification and strengthening, which is why the first conversation should be about load rather than injection.

Is tennis elbow an inflammation?

No. Biopsy studies show disorganised collagen and new vessel and nerve ingrowth with inflammatory cells largely absent, which is why it is described as a tendinopathy rather than a tendinitis.

Does PRP hurt more than a steroid injection?

Yes, usually for the first few days, because the intended effect is a healing response rather than suppression of one. That settles, and the loading programme continues alongside.

Why do I keep getting tendon problems in different places?

In women in their 40s and 50s this commonly reflects the connective tissue changes of falling oestrogen, since oestrogen receptors are present in tendon. Diabetes and smoking also impair tendon healing.
