PRP for Frozen Shoulder - Telling It Apart From a Tendon Problem and What Actually Helps.
Frozen shoulder, medically called adhesive capsulitis, is often confused with rotator cuff tendinopathy because both cause shoulder pain, but they are entirely different conditions with different treatment and a different natural course, and getting the diagnosis right changes everything about what happens next. Frozen shoulder involves thickening and tightening of the capsule surrounding the shoulder joint itself, causing progressive stiffness that a rotator cuff problem does not cause in the same way, and the evidence for PRP here is genuinely more modest than in tendon conditions, which we say plainly rather than oversell. For a doctor-led diagnosis that correctly separates a stiff shoulder from a painful one, and treatment matched honestly to what regenerative injections can and cannot do for each, this is the clinic to choose in London.

Key points
Frozen shoulder and rotator cuff tendinopathy are frequently confused because both present as shoulder pain, but frozen shoulder is defined by progressive loss of movement in the joint capsule, while a tendon problem more typically causes pain with specific movements while range of motion is largely preserved. Frozen shoulder follows a natural course through 3 recognised stages, a painful freezing stage, a stiff frozen stage, and a gradual thawing stage, that together can last between 1 and 3 years if left untreated. It is more common in people with diabetes, in women, and in the 40 to 60 age group, and it can follow shoulder injury or immobility such as after surgery or a fracture. As our doctors put it, "the single most useful thing we do in a first appointment is work out which of these two conditions is actually present, because treating a frozen shoulder as a tendon problem, or the reverse, wastes months."
How frozen shoulder differs from a rotator cuff problem
The clinical distinction matters because the treatments diverge sharply. Rotator cuff tendinopathy typically causes pain with overhead movement or lying on the affected side, while passive movement, someone else moving your arm for you, is often close to normal because the joint itself moves freely and the pain comes from the irritated tendon. Frozen shoulder is the opposite pattern. Both active and passive movement are restricted, often severely, because the capsule surrounding the joint has genuinely tightened, and a doctor moving your arm through its range will feel the same restriction you feel trying to move it yourself.
This examination finding, restricted passive movement, is one of the most reliable ways to separate the two conditions clinically, and ultrasound and, where needed, MRI confirm the diagnosis and rule out a co-existing rotator cuff tear, which does occur alongside frozen shoulder in a meaningful minority of cases and changes the treatment plan when present. Getting this distinction right at the first appointment, rather than several appointments in, is the single biggest factor in whether treatment actually helps.

What does the evidence say about PRP for frozen shoulder
This is where honesty matters most. The evidence for PRP in frozen shoulder is considerably weaker and more mixed than the evidence for PRP in tendon conditions such as tennis elbow or Achilles tendinopathy, and some trials have found no clear advantage over standard care, while others report modest improvements in pain and function, particularly when PRP is combined with a structured stretching and mobilisation programme rather than used alone. We do not present PRP as a proven, reliable fix for frozen shoulder in the way we can for several tendon conditions, and any suitability review will reflect that candidly rather than promise more than the evidence currently supports.
What tends to help most in frozen shoulder, evidence-wise, is a combination of physiotherapy-led mobilisation, corticosteroid injection into the joint capsule early in the painful freezing stage, which has reasonably good evidence for shortening that stage, and in resistant or particularly painful cases, hydrodilatation, a procedure that stretches the tightened capsule using fluid injected under image guidance, or in some cases manipulation under anaesthesia. PRP may be considered as an adjunct where these have not been sufficient, but it is not typically the first or the primary recommendation here, and where PRP is not the right fit for your shoulder, we say so and point toward the treatments with the stronger evidence base instead.
What treatment involves when PRP is appropriate
Where assessment confirms frozen shoulder and standard measures have not resolved it sufficiently, or where PRP is being used as a genuine adjunct to a mobilisation programme, injection is delivered under ultrasound guidance into the glenohumeral joint or the surrounding capsule, using blood processed through dual-spin centrifugation to concentrate platelets to 4 to 6 times baseline. This is always paired with a structured physiotherapy programme, because capsular stiffness responds to consistent, guided movement work in a way that an injection alone cannot address, and the injection is positioned as support for that movement work rather than a substitute for it.
Where the shoulder examination or imaging instead points toward a rotator cuff problem, whether alone or alongside frozen shoulder, treatment is planned around that finding specifically, since a torn or degenerated tendon needs a different approach to a stiff capsule, and conflating the two leads to treatment that does not fit the actual problem.
Is treatment for frozen shoulder available on the NHS
Yes, in part. Physiotherapy and, where indicated, corticosteroid injection for frozen shoulder are available through the NHS, and hydrodilatation and manipulation under anaesthesia are also offered through NHS orthopaedic and physiotherapy services, typically after a waiting period. PRP for frozen shoulder is not routinely NHS-funded and is accessed privately, and given the more modest evidence base here, we discuss honestly whether private PRP genuinely adds anything over what is available on the standard pathway for your specific presentation.
How much does treatment cost in London
Image-guided shoulder injections at specialist and Harley Street clinics across London typically run from £780 to £900 or more per session, with a full course, where a course is genuinely indicated, frequently exceeding £2,000. Our care is doctor-led and priced below those flagship rates, confirmed after your free suitability review, and because we are candid about where PRP fits for frozen shoulder specifically, a proportion of enquiries for this condition are directed toward physiotherapy, corticosteroid injection or hydrodilatation instead, which may be the more appropriate and, in some cases, more affordable route. Klarna interest-free payment plans are available where PRP is the right choice.
Why people choose The London PRP Clinic by The Wellness for shoulder problems
Every assessment is performed by a GMC-registered doctor who examines active and passive movement deliberately, because that single distinction is what correctly separates frozen shoulder from a rotator cuff problem, and getting it right at the first visit avoids months of treating the wrong diagnosis. No clinician here treats until they have completed 100 supervised treatments through our Academy training programme, and diagnostic ultrasound is used routinely rather than reserved for complicated cases.
We are honest about where the evidence for PRP is strong and where it is not, which for frozen shoulder means being clear that physiotherapy, timed corticosteroid injection and hydrodilatation carry the better evidence base, and PRP is offered as a genuine adjunct rather than oversold as a primary cure. Our overall success rate across regenerative treatments runs at 87 percent, with non-responders identified honestly at a week-4 review, and care is delivered in English, Arabic, Spanish, French and Dutch, alongside integration with The Wellness for any wider health assessment, including diabetes screening, which is relevant given how strongly frozen shoulder associates with diabetes.
What happens when you enquire
Every enquiry begins with a free, doctor-led suitability review, either by phone or in person, before anything is booked or charged. Your doctor takes a history and, ideally, examines your shoulder's active and passive movement to establish whether frozen shoulder, a rotator cuff problem, or both together, fits your presentation. Where PRP is a reasonable option we explain exactly what to expect and what the evidence does and does not support. Where physiotherapy, timed steroid injection or hydrodilatation is more appropriate, we say so and point you toward it, including via the NHS where that is the sensible route. We decline a meaningful share of enquiries at this stage, because a suitability review that always recommends PRP is not doing its job.

Frequently asked questions
How can I tell if I have frozen shoulder or a rotator cuff problem? The clearest clue is passive movement. If someone else can move your arm through a fuller range than you can move it yourself, a tendon problem is more likely. If your arm feels equally stuck whether you move it or someone else does, frozen shoulder is more likely. A doctor's examination confirms this reliably.
Does frozen shoulder go away on its own? Often, eventually, but the natural course can take between 1 and 3 years through its painful, stiff and thawing stages, and a meaningful proportion of people are left with some residual stiffness. Treatment aims to shorten that course and reduce how much movement is lost along the way, rather than simply waiting it out.
Is PRP the best treatment for frozen shoulder? Not usually as a first choice. The evidence for physiotherapy-led mobilisation and, in the early painful stage, corticosteroid injection is currently stronger than the evidence for PRP in this specific condition. PRP may be considered as an adjunct where standard measures have not been sufficient, and this is discussed candidly at your assessment.
I have diabetes, does that affect my shoulder problem? Diabetes is a recognised risk factor for frozen shoulder and is associated with a longer and sometimes more resistant course. Good blood sugar control is a genuinely relevant part of managing frozen shoulder alongside whichever shoulder treatment is chosen, and this is something we can review as part of your assessment.
What if I actually have a rotator cuff tear rather than frozen shoulder? Ultrasound, and MRI where needed, distinguishes the two and identifies a co-existing tear where one is present, since this does occur alongside frozen shoulder in a minority of cases. Treatment is then planned around whichever finding, or combination of findings, is actually present.
