PRP for Tendon and Sports Injuries in London: Evidence, Safety and What to Assess First

If you want a clear decision rather than another injection, an assessment should establish what is causing the pain, what treatment you have already tried and what improvement would matter to you. The London PRP Clinic can discuss whether PRP belongs in that plan. It should also be possible to explain why an injection is not the right next step.

Ask about a tendon assessment on WhatsApp or email team@thewellnesslondon.com. Joint PRP is £750 per session. For a tendon-specific assessment and treatment plan, request the full written fee before deciding; do not assume the joint price covers every injury or investigation.

What PRP means, and what it does not prove

Platelet-rich plasma is prepared from a sample of your own blood and injected into the treatment area. The biological rationale is not the same as proof that patients recover better. An injection can be technically well performed and still offer little benefit for a particular condition. The relevant question is whether trials show a worthwhile improvement in pain, function or activity for people with your diagnosis.

NICE describes PRP within its guidance on autologous blood injection for tendinopathy. Its recommendation is explicit: efficacy evidence remains inadequate, and the procedure should be used only with special arrangements for clinical governance, consent and audit or research. This is not a routine endorsement or a guarantee of recovery.

Tennis elbow: compare the strongest evidence, not the most attractive percentage

The 2021 Cochrane review of autologous blood and PRP for lateral elbow pain found moderate-certainty evidence of little or no clinically important benefit in pain or function compared with placebo. Its main comparison was at three months. The review also found no clinically important pain or function benefit at six or twelve months.

This matters if you have seen a headline saying PRP is better than cortisone. The choice of comparison changes the conclusion. A better result than a particular steroid protocol does not answer whether an injection adds enough benefit to justify its cost and risks. Ask for the relevant evidence and the expected absolute improvement, not only a success rate without a definition.

Achilles tendon pain: a large trial did not show the promised advantage

A 2021 JAMA trial studied 240 adults with chronic midportion Achilles tendinopathy. A single PRP injection did not reduce tendon dysfunction compared with a sham injection at six months. Mean VISA-A scores, which measure symptoms and activity on a 0 to 100 scale, were 54.4 after PRP and 53.4 after sham; the difference was not statistically significant.

The finding applies to the condition and single-injection protocol tested. It should not be stretched into a claim about every tendon or every PRP preparation. Equally, it is not reasonable to promise that an Achilles tendon will heal faster because the injection contains growth factors.

Patellar tendon, shoulder and other sports injuries need their own decision

Jumper's knee, shoulder pain, a tendon tear and pain around a joint are not interchangeable diagnoses. Evidence from knee osteoarthritis does not establish that PRP works for a patellar tendon. Nor can results from one tendon be used to promise an outcome in another.

For an injury outside the conditions discussed above, ask the clinician to show you the evidence for that exact diagnosis and proposed protocol. If the answer relies on a small study, a different condition or a biological explanation, that uncertainty belongs in the discussion before you pay. There is no universal tendon success figure on this page.

Discuss your injury and previous treatment. Include where the pain is, how long it has been present, what activities you want to return to and whether you already have a report or scan.

What a useful assessment should leave you with

Before choosing an injection, ask for a plan that covers:

• The working diagnosis and whether the pain could have another cause.
• Whether imaging would change the decision, rather than ordering a scan automatically.
• What rehabilitation has been tried, for how long, and what should change next.
• Alternatives to PRP, including continuing rehabilitation or obtaining a specialist opinion.
• The proposed injection protocol, its evidence and its risks.
• A practical activity plan and a named follow-up point.
• The total fee and what happens if the expected improvement does not occur.

A concrete goal is more useful than a vague promise to regenerate a tendon. Examples to discuss include tolerating a normal working day, walking a usual route or returning gradually to a particular activity. Agree how pain and function will be recorded before treatment so follow-up measures something that matters to you.

Rehabilitation, medicines and safety come before a treatment promise

The NHS tendonitis guidance describes physiotherapy for persistent or limiting symptoms, with specialist referral when appropriate. It also describes steroid injections as a possible source of short-term pain relief in some severe cases. That does not make one treatment automatically right for every tendon.

Bring your medicine list to assessment, including aspirin, anticoagulants, anti-inflammatory tablets and supplements. Do not stop prescribed medicine because a blog or clinic checklist says to do so. Any change must be agreed with the clinician responsible for it. Our PRP and medicines guide explains the questions to discuss.

Injections cause discomfort and carry risks, including infection. Cochrane notes these risks even when trials do not show a higher adverse-event rate than placebo. Your consent discussion should cover the specific risks of the proposed procedure and the uncertainty about benefit.

Sudden severe pain during activity, especially with a popping or snapping sensation, may indicate a ruptured tendon. Seek urgent advice rather than waiting for a routine PRP appointment. The NHS advises contacting 111 if you are in a lot of pain or think you have ruptured a tendon.

Cost and the questions worth asking before you commit

Joint PRP at The London PRP Clinic is £750 per session. Tendon plans need a written quote for the specific assessment, procedure and follow-up proposed. Ask whether imaging, any further appointments and additional injections are included. A package should not replace a discussion about whether any injection is appropriate.

There is no reliable promise on this page that PRP avoids surgery, regenerates torn tissue or gets you back to sport by a fixed date. The value of an assessment is a defensible next decision, including the decision not to inject.

Arrange a tendon assessment in London

The London PRP Clinic is a doctor-led regenerative medicine practice in Marylebone, adjacent to Harley Street. It is part of The Wellness. This article is general information, not a diagnosis or an individual treatment recommendation.

Enquire on WhatsApp, email the team or use the contact page. Ask for an assessment, the evidence for your injury and a full written treatment quote before deciding.
