Achilles Tendon Rupture
Written by Dr Joshua Hatch, Musculoskeletal GP, RACGP Fellow, Diploma in Musculoskeletal Medicine (FSEM UK).
An Achilles tendon rupture usually occurs during a sudden, forceful push-off or landing. It is a disabling injury, and because the tendon begins to shorten and scar over time, prompt diagnosis and early treatment matter.
Assessment is largely clinical, using the calf-squeeze (Thompson) test and examination, with ultrasound to confirm the tear and guide management. It is important not to miss the diagnosis, as some people retain a little foot movement despite a complete tear.
Both non-surgical (functional bracing with a boot and wedges) and surgical pathways rely on starting early with the foot correctly positioned. Modern non-surgical rehabilitation gives results comparable to surgery for many people, while surgery may suit selected patients. Because immobilisation raises the risk of a blood clot, clot-prevention measures should be discussed. Treatment is coordinated with an appropriate specialist.
Common symptoms
- A sudden pop or snap at the back of the ankle, often with a feeling of being kicked
- Severe pain and swelling near the heel
- Difficulty walking or pushing off, and trouble standing on the toes
- Weakness of the calf on the injured side

Evidence for twelve treatment options in achilles tendon rupture
This is not a fixed ladder or a package of treatments. Every option is assessed independently against this diagnosis, including treatments with limited direct research that may still be reasonable for a clearly defined tissue target. The evidence level, likely benefit, risks, cost and alternatives are weighed at consultation.
Foundation: diagnosis, education and rehabilitation
The part of care with the broadest relevance. For many people it is enough on its own; other options are judged against it, not automatically added after it.
Diagnosis, education and progressive rehabilitation Working out what is driving the pain, explaining what your imaging does and does not mean, and building a graded loading plan you can actually follow. Core care
What it involves
Assessment to identify the likely pain source, an explanation of what the diagnosis means, adjustment of the loads that aggravate it, and a progressive strength and conditioning plan, with weight management where that is clinically relevant.
What the evidence shows
For degenerative structural problems, exercise matches surgery. A trial of 321 patients found exercise-based physiotherapy non-inferior to arthroscopic partial meniscectomy for knee function at five years, with the same rate of radiographic osteoarthritis progression (Noorduyn, JAMA Netw Open 2022), confirming an earlier trial at two years that also found better thigh strength in the exercise group (Kise, Br J Sports Med 2016). Even in adults aged 18 to 40 with MRI-verified tears, traumatic or not, early surgery was no better than twelve weeks of exercise and education at one year (Damsted, J Orthop Sports Phys Ther 2024).

Where it fits
A tear on a scan is not automatically the thing to fix. Rehabilitation comes first, with surgical review where the history, examination and imaging together point to a problem that loading will not solve: mechanical locking, instability, or a failure to progress despite doing the work.
Muscle and symptom-modifying options
Useful only when the examination identifies the tissue they target or when short-term pain control creates a useful rehabilitation window.
Wet needling and trigger point injection (trigger point injection) A fine needle into a tender band of muscle, with a small volume of dilute glucose solution injected through it. Only if relevant
What it involves
The needle is placed into the tender muscle band and a small volume of 5% glucose with a very dilute local anaesthetic (0.02-0.08%) is injected. Often done in the same visit as your assessment, and usable where the tender area sits deeper. Dry needling (the same technique with nothing injected) is not offered here.
What the evidence shows
Trigger-point injection reviews address confirmed myofascial pain and find heterogeneous, generally low-certainty results; they do not establish the technique as treatment for the underlying diagnosis. Condition reviewed: achilles tendon rupture.
Evidence source: Debrosse et al., trigger-point injection systematic review (2022)
Pairing reviewed 2026-08-30.
Where it fits
For achilles tendon rupture, this may be considered only when examination finds a separate tender muscle band reproducing part of the pain. It does not treat the primary pathology and is used to help movement or rehabilitation.
Ultrasound-guided injections Guidance means the needle can be seen reaching the target. What goes into the needle depends on the diagnosis. Worth discussing
What it involves
The injection is performed under ultrasound so the needle can be watched into the target structure. What is injected is decided by the diagnosis, and corticosteroid is used sparingly, for the reasons set out below.
What the evidence shows
Ultrasound improves needle-placement accuracy, but guidance is not a treatment in itself: benefit depends on a valid injectable target and what is injected. Condition reviewed: achilles tendon rupture.
Evidence source: Oo et al., ultrasound-guided injection systematic review (2024)
Pairing reviewed 2026-08-30.
Where it fits
For achilles tendon rupture, an ultrasound-guided injection is considered only when there is a specific diagnostic question or a separate joint, bursa, sheath or nerve target. The injectate and purpose are stated before treatment.
V-ACTOR vibration therapy (vibration therapy) Low-frequency vibration applied over tender muscle. Not a shockwave, despite sharing the machine. Not offered for this
What it involves
A vibration handpiece is moved over the tender muscle and fascia for a few minutes. It runs from the same STORZ MASTERPULS icon console as radial shockwave but is a separate handpiece delivering a different, gentler form of energy. No needles, no anaesthetic, no downtime.
What the evidence shows
Not appropriate over a systemic inflammatory process, healing bone, an area of osteonecrosis or a complete tendon or ligament rupture.
Pairing reviewed 2026-08-30.
Where it fits
Not offered for this.
Energy-based treatment options
Radial pressure wave, focused shockwave and EMTT have different targets and different evidence. They are assessed separately rather than treated as one category.
Radial or focused shockwave? Read the overviewRadial shockwave (radial pressure wave) Broad treatment across tender muscle and fascia, close to the surface. Not for the tear; rupture reported after
What it involves
A handpiece is moved over the tender tissue while ballistic pressure pulses are delivered, using a transmitter head chosen for the tissue, including heads shaped for fascia and for the muscle either side of the spine. The pulse is strongest at the skin and weakens with depth, so this is mainly a myofascial treatment, though it can reach deeper in some areas. No anaesthetic, no downtime, usually a course of sessions about a week apart.
What the evidence shows
No controlled study of radial shockwave for an acute or surgically repaired Achilles rupture was found. A search on 11 November 2026 of shockwave terms with Achilles rupture or repair returned 33 records, and a randomised-trial and systematic-review pass returned four, none of them in rupture. The radial reports run the other way. A 61-year-old man with ten years of mid-tendon pain had six radial sessions, became pain-free and returned to sport, then ruptured the tendon six months later stepping off a pavement; the authors note that feeling better may not mean the tendon has regained its strength (Briffa, Cureus 2026). An earlier case report also describes rupture after radial treatment (Argyropoulou, J Surg Case Rep 2025; read for the focused row on 22 October 2026). Case reports cannot show that the treatment caused the rupture.
Pairing reviewed 2026-11-11.
Where it fits
Not used on a ruptured or repaired tendon. Considered only for a separate tendon or muscle problem, once the rupture is being managed and a graded rehabilitation programme is under way.
Focused shockwave (ESWT) A true shock wave converging at depth: for tendon, joint, ligament and bone. No rupture trials; rupture reports
What it involves
A focused system generates an acoustic shock wave that converges at a focal point set at a defined depth, concentrating the energy where the target is. This is the form used for tendon, joint, ligament and bone. Typically four to six sessions about a week apart, no anaesthetic and no formal downtime.
What the evidence shows
No controlled study of shockwave for an acute or surgically repaired Achilles rupture was found. Search: PubMed, shockwave terms with Achilles or calcaneal tendon and rupture, repair or tear, animal work excluded (21 records), with a trial and systematic-review pass. The only rupture data are three cases, one a complete rupture repaired and re-ruptured twice, reported as recovered on MRI with no numbers and no device type (Ringeisen, Orthopadie 2026), and one partial tear treated with a focused device (Hsu, J Pain Res 2017). The harm signal runs the other way: two tendon ruptures in the treated group of a placebo-controlled trial in chronic Achilles pain (Costa, Clin Orthop Relat Res 2005), counted by a 2026 meta-analysis as ruptures after focused treatment (Korakakis, J Orthop Sports Phys Ther 2026), and case reports of rupture after radial treatment (Argyropoulou, J Surg Case Rep 2025; Briffa, Cureus 2026, whose authors could not infer a cause).
Pairing reviewed 2026-10-22.
Where it fits
Considered only for a coexisting tendinopathy, not for the tear.
EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Usually painless, no contact. Only if relevant
What it involves
You sit with the applicator positioned over the area for a short session. It is usually painless and needs no gel or skin contact. It is usually given as a course, commonly alongside shockwave.
What the evidence shows
No evidence in this condition, and the rationale offered for EMTT (an effect on tendon and soft-tissue cell behaviour) does not apply to a systemic, bone or complete structural problem.
Pairing reviewed 2026-08-30.
Where it fits
Not part of the plan here.
Biologic and joint injection options
Each injection is assessed independently for the named diagnosis. Cost, uncertainty, likely benefit, risks and alternatives are part of the decision.
Platelet-rich plasma (PRP) Your own blood, concentrated and injected under ultrasound guidance. Not offered for this
What it involves
Blood is taken from your arm, spun to concentrate the platelets, and injected into the target under ultrasound guidance in the same appointment.
What the evidence shows
PATH-2 settled this. 230 adults with acute Achilles rupture managed non-surgically were randomised to platelet-rich plasma or a placebo injection, and at 24 weeks there was no difference in tendon function, patient-reported function, quality of life or adverse events (Keene, BMJ 2019). The two-year follow-up found the same (Keene, Bone Joint J 2022). This is not an absence of evidence. It is good evidence of absence.
Pairing reviewed 2026-08-30.
Where it fits
Not offered for a ruptured Achilles. The plan is the rehabilitation protocol and, where indicated, surgical review: an injection adds cost and a needle without adding recovery.
Prolotherapy (dextrose) A course of dextrose injections into and around the structure and its attachments. No study in a ruptured tendon
What it involves
Hypertonic dextrose is injected at the tender ligament and tendon attachments, and into the joint where relevant, usually as a series of treatments a few weeks apart.
What the evidence shows
No study has tested prolotherapy for a ruptured Achilles tendon. PubMed searches on 17 October 2026 (prolotherapy, dextrose injection, hypertonic dextrose or hypertonic glucose with Achilles rupture or tendon rupture, then randomised-trial and systematic-review passes) found no clinical study in rupture. The human prolotherapy studies at the Achilles are all in tendinopathy, a different condition, and the largest of them excluded anyone with a past rupture (Pham, J Am Podiatr Med Assoc 2025, 132 people, retrospective). The only rupture-related work is in rats: 12.5% dextrose injected into healthy rat Achilles tendons did not weaken them (Martins, Knee Surg Sports Traumatol Arthrosc 2012). That is animal work on an intact tendon and says nothing about healing a tear.
Pairing reviewed 2026-10-17.
Where it fits
A ruptured tendon is not something an injection can repair. The plan is the functional rehabilitation protocol, with surgical review where indicated. Prolotherapy is considered only for a separate ligament or tendon problem later in recovery, assessed on its own evidence.
Viscosupplementation (hyaluronic acid) A gel-like injection into an arthritic joint. Widely used, and genuinely contested. Only if relevant
What it involves
One or a short series of hyaluronic acid injections into the joint under ultrasound guidance.
What the evidence shows
Hyaluronic acid evidence is concentrated in osteoarthritis (especially the knee) and remains contested; it cannot be extrapolated to a non-arthritic tissue or a different diagnosis. Condition reviewed: achilles tendon rupture.
Evidence source: Pereira et al., large-trial injection review (2024)
Pairing reviewed 2026-08-30.
Where it fits
For achilles tendon rupture, this is relevant only when a symptomatic arthritic peripheral joint is the actual target. It is not used for muscle, tendon, ligament, nerve, fracture or spinal pathology.
Nerve-targeted options
Relevant when examination identifies a superficial neuropathic pattern or a compressed peripheral nerve, not simply because pain is present.
Lyftogt perineural therapy (perineural injection therapy) A series of small dilute dextrose injections just under the skin, over tender superficial nerves. Only if relevant
What it involves
Small injections of low-concentration dextrose, usually 5%, placed just beneath the skin along tender superficial nerves. Given as a series of short sessions.
What the evidence shows
Perineural dextrose evidence is concentrated in diagnosed peripheral compression neuropathies, particularly the upper limb; no direct evidence was identified for this diagnosis itself. Condition reviewed: achilles tendon rupture.
Evidence source: Perineural dextrose for upper-limb entrapment neuropathy review (2025)
Pairing reviewed 2026-08-30.
Where it fits
For achilles tendon rupture, perineural treatment may be considered only if a separate superficial neuropathic pain pattern is found on examination. It is not treatment of the primary diagnosis.
Ultrasound-guided nerve hydrodissection Fluid placed around a nerve to free it from the surrounding tissue. Only if relevant
What it involves
Under ultrasound, fluid is placed in the plane around the nerve to separate it from the tissue that is tethering or compressing it.
What the evidence shows
Searched 10 November 2026 (PubMed: hydrodissection, hydrorelease or perineural injection with tendon rupture, Achilles, patellar tendon, quadriceps tendon, tendon repair or sural nerve, 23 records; Achilles rupture with sural nerve, nerve entrapment or neuroma and injection or ultrasound guidance, 8 records; a randomised-trial and systematic-review pass returned none). No study has tested hydrodissection for a torn Achilles tendon, and it cannot repair one. The rupture records are about surgical technique: in one comparison, 3 of 19 people repaired through an open incision had a sural nerve injury against none of 22 with a small-incision ultrasound-assisted repair, with no treatment of the nerve described (Wang, J Orthop Surg Res 2025). The nearest hydrodissection reports concern the same nerve after other surgery near the heel: a sural nerve caught in scar after a heel-bone fracture operation, with over 90% relief after two ultrasound-guided sessions of 5% dextrose (Yoon, Cureus 2025), and another where hydrodissection helped but the pain fully settled only after the plate was removed and the nerve freed surgically (Omodani, Cureus 2023). Both are single cases with no comparison.
Pairing reviewed 2026-11-10.
Where it fits
Not a treatment for the ruptured tendon, which is managed with a functional boot or surgery and a staged rehabilitation program. Considered only if burning, numbness or nerve pain along the outer heel and foot persists after healing, which points to the sural nerve rather than the tendon.
This is general information only and suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of the uncertainty, the expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
Every treatment above is described in full on the non-surgical treatments page, including what each one is used for and what the evidence supports. Ratings apply to the named diagnosis; an adjacent muscle, tendon, joint or nerve problem is assessed as a separate target. The method behind the ratings, and the treatments not offered, are set out on the evidence page.
Corticosteroid injection is reviewed separately for each diagnosis.
Cortisone reliably reduces pain in the short term, and that can be genuinely useful when pain is stopping you sleeping or moving enough to rehabilitate. Beyond that window the picture changes. A systematic review of 41 randomised trials and 2,672 participants found that corticosteroid injection reduced pain in the short term but that the effect reversed at intermediate and long term; in pooled analysis for lateral epicondylalgia the short-term effect was large (SMD 1.44, 95% CI 1.17 to 1.71) while no intervention was favoured at 26 weeks (-0.40, -0.67 to -0.14) and at 52 weeks (-0.31, -0.61 to -0.01) (Coombes, Lancet 2010). In a randomised trial in lateral epicondylalgia, 83 per cent of the corticosteroid group had completely recovered or much improved at one year against 96 per cent given a placebo injection, and recurrence ran at 54 per cent against 12 per cent; adding physiotherapy made no significant difference at one year (Coombes, JAMA 2013). In joints, repeated corticosteroid injections have been associated with cartilage loss. It does not repair anything.
So treatment plans are not built around it. Where an injection is the right call, the specific diagnosis and target are reviewed, what is being injected and why is discussed, the number is kept low, and it is paired with the loading work that changes the longer-term course.
When it might still be considered
- Pain severe enough to block rehabilitation
- A clear inflammatory or bursal target on imaging
- A specific short-term goal: a trip, a procedure, a return to work
- Diagnostic use, where the response shows where the pain is coming from
When a cortisone injection is worth doing, and when it is not
Other foot, ankle & lower leg conditions
Pain in the same area can come from more than one source, and the label matters less than what the examination and history point to. These are the other guides for this region.
