Achilles tendon rupture vs tendinopathy: how to tell them apart and what each really means
Achilles tendon pain sits on a spectrum, and where you are on it changes everything about what happens next. At one end is tendinopathy: a grumbling, overloaded tendon that needs months of patient loading. At the other is rupture: a snapped tendon, a medical emergency, and a decision between surgery and a cast within days. Confusing the two, or hoping a rupture is just a bad strain, costs people their best chance of a full recovery. At The London PRP Clinic by The Wellness, tendon assessments are done by GMC-registered doctors, and part of that job is telling you quickly and plainly which problem you have, even when the answer is "you need a hospital, not us".
Key points
Tendinopathy is a gradual overload problem: morning stiffness, pain that warms up, thickening of the tendon. It is managed with loading programmes, and sometimes PRP, over months.
A rupture is sudden: a snap or kick sensation, immediate weakness, inability to push off or stand on tiptoe. It is a same-day emergency.
Ruptures are treated with surgery or structured conservative management in a boot, decided urgently with a specialist.
PRP has no role in treating an acute rupture; anyone offering it for that should be questioned hard.
Long-standing tendinopathy and steroid injections around the tendon both raise rupture risk, which is why proper tendinopathy care matters.
Joint and tendon PRP at The London PRP Clinic by The Wellness starts from £750 per treatment area, for suitable chronic tendon problems.
What tendinopathy feels like
Tendinopathy builds gradually. The classic pattern is stiffness and pain at the back of the heel first thing in the morning or at the start of a run, easing as the tendon warms up, then returning after activity or the next day. The tendon may be visibly or palpably thickened, and the story usually stretches over weeks or months, often with a training change or a period of extra load at the start. Tendinopathy is not a tear and does not become a rupture overnight, but it does weaken the tendon over time if ignored, and it deserves proper treatment rather than bargain management.
What a rupture feels like
A rupture is unmistakable in most cases: a sudden sharp pain in the back of the ankle, often described as being kicked or hit, sometimes with an audible snap, during a push-off, sprint, jump or even a mis-step. Walking becomes immediately difficult, pushing off is weak or impossible, standing on tiptoe on that leg fails, and there may be a gap you can feel in the tendon. Occasionally the pain settles quickly and people persuade themselves it was a strain; the weakness does not lie. If any of this sounds familiar, stop, keep weight off it, and get assessed the same day, because the treatment window matters.
How each is treated
Tendinopathy is treated with a progressive loading programme over twelve weeks or more, with options like shockwave or PRP considered when a well-run programme has plateaued, as covered in our articles on PRP versus steroid for Achilles pain and insertional versus midportion tendinopathy. A rupture is treated either surgically, with the tendon repaired, or conservatively in a boot with a structured rehabilitation protocol, a decision made urgently with a specialist based on the tear, your age, activity and health. Both rupture routes take months, and both are orthopaedic territory, not ours.
Where PRP genuinely fits, and where it does not
PRP is a treatment for chronic tendon disease, not for a snapped tendon. In an acute rupture the priority is mechanical: the tendon ends need to heal in the right position under specialist care, and no injection substitutes for that. We will never offer PRP for an acute rupture, and if we suspect one at consultation, you will be redirected the same day with a clear explanation. Where PRP earns its place is the chronic end: tendinopathy that has plateaued despite proper loading, where supporting the tendon's repair with a favourable safety profile is a reasonable next step. That honest boundary is part of what a doctor-led clinic is for.
Protecting a vulnerable tendon
The best rupture is the one that never happens. The tendons most at risk are the ones already carrying tendinopathy, tendons in people in their thirties to fifties doing stop-start sport, and tendons that have had steroid injections nearby, which is one reason specialists avoid them around the Achilles. Treating tendinopathy properly, loading progressively, and taking sudden heel pain seriously are the practical protections. If you have had months of grumbling Achilles pain and keep meaning to get it looked at, that appointment is cheap insurance.
What it costs
At The London PRP Clinic by The Wellness, consultations are £59 by phone for 15 minutes, £150 by video and £220 in person at our Marylebone clinic, and joint and tendon PRP starts from £750 per treatment area for suitable chronic cases. If your tendon needs a hospital rather than an injection, the consultation is all you pay for, and you leave knowing exactly where to go and why.
Why people choose The London PRP Clinic by The Wellness
We are a doctor-led PRP clinic: every case is assessed and injected by a GMC-registered doctor, and the assessment comes before any treatment discussion. A clinic that only sells injections will always find a reason to inject; a doctor-led clinic will also tell you when the answer is a physiotherapist, a boot, or a surgeon.

Frequently asked questions
How do I know if I have ruptured my Achilles or just strained it?
A rupture usually involves a sudden snap or kick sensation during push-off, immediate difficulty walking, weak or absent push-off, and failure to stand on tiptoe on that leg. A strain or tendinopathy is milder and gradual. If there is any doubt, treat it as a rupture and get same-day assessment, because early decisions change outcomes.
Is Achilles rupture always treated with surgery?
No. Many ruptures are managed in a boot with a structured rehabilitation protocol, and surgical repair is the other main option. The choice depends on the tear, your age, activity level and health, and is made urgently with a specialist. Both routes take months of rehabilitation.
Can PRP heal an Achilles rupture?
No, and we will never offer it for one. An acute rupture needs the tendon ends to heal in the right position under specialist surgical or boot-based care. PRP's role is in chronic tendinopathy that has plateaued on loading, a completely different situation.
Does Achilles tendinopathy lead to rupture?
Not usually, but long-standing untreated tendinopathy weakens the tendon and modestly raises rupture risk, as do steroid injections near the tendon. Treating tendinopathy properly with a loading programme is the practical way to protect the tendon.
I am in my forties and play five-a-side. Should I worry?
Ruptures are most common in people in their thirties to fifties doing stop-start sports, particularly with a history of tendon pain. You do not need to stop playing, but a grumbling Achilles deserves assessment, and a proper warm-up and progressive loading genuinely reduce risk.
How much does an Achilles assessment cost at The London PRP Clinic?
Consultations are £59 by phone for 15 minutes, £150 by video and £220 in person. Joint and tendon PRP, for suitable chronic tendon problems, starts from £750 per treatment area.
