Shockwave therapy is well studied in several lower-limb tendinopathies, but peroneal-specific evidence remains limited. That makes diagnosis particularly important. A patient with uncomplicated load-related tendinopathy may be a reasonable candidate for an adjunctive tendon treatment, while a split tear or dynamic subluxation raises a different management question.

For peroneal tendon problems, the research on diagnosis is considerably stronger than the research on shockwave itself.
Three levels of evidence
It helps to separate the research into three layers:
- Direct peroneal-specific shockwave evidence. Sparse, consisting mainly of individual case reports in which shockwave was combined with other treatments.
- Broader lower-limb tendinopathy evidence. Supports shockwave as a class of treatment for tendon pain, but not a peroneal-specific effect size.
- Diagnostic and structural evidence. Much stronger for peroneal disorders, and it shows how often tendinopathy, tears and instability overlap.
The practical consequence is that correct diagnosis matters more than pretending the condition-specific shockwave literature is mature.
What broader tendinopathy research shows
Broader tendinopathy literature supports ESWT as a treatment class, but those findings cannot be directly converted into a peroneal-tendon-specific effect size.
A 2018 meta-analysis of 29 randomized trials found that shockwave had a positive overall effect on pain and function in lower-limb tendinopathy, with effects seen at short-term follow-up and at 3, 6 and 12 or more months. Shockwave type and dose appeared to influence results.
Trials in Achilles tendinopathy, plantar fasciitis, patellar tendinopathy and greater trochanteric pain syndrome cannot simply be transferred to the peroneal tendons. Those tendons differ in anatomy, loading and how often their problems involve tears or instability.
A 2026 case report: peroneus longus tear in a professional footballer
A 2026 case report described successful nonoperative management of an isolated peroneus longus tear in a professional football player using a combined program of focused ESWT, physiotherapy and custom orthotics. The result is clinically interesting but cannot establish that shockwave caused the recovery.
The player, in his late twenties, had an isolated longitudinal peroneus longus tear. Treatment included eight sessions of ultrasound-guided focused shockwave at 2,500 to 4,000 impulses per session and energy levels reported between 50 and 550 µJ/mm², alongside physiotherapy with progressive loading and custom orthotics. Pain fell from 7 to 1 on a 10-point scale and the AOFAS ankle-hindfoot score rose from 57 to 95, maintained at 18 months. MRI after six weeks showed reduced signal change and a shorter lesion. He returned to training at eight weeks and full competition at 12 weeks.
Limitations. This is a single case in an elite athlete with access to intensive rehabilitation. Shockwave was one part of a combined program, there was no control, and the condition was a tear rather than straightforward tendinopathy. The authors described the injury as acute, and some acute tendon injuries improve with conservative care alone. The case cannot show how much shockwave contributed, and it is not evidence that shockwave routinely heals peroneal tendon tears.
A painful os peroneum case
Shockwave has also appeared in isolated case literature involving painful os peroneum syndrome, but these reports are multimodal and should not be treated as evidence for routine peroneal tendinopathy.
A 2023 case report described a 59-year-old man with severe load-dependent pain from painful os peroneum syndrome, with inflammation of the peroneus longus tendon and its sheath attributed to a flat, outward-rolling foot posture. Multifactorial conservative care, including injection therapy and shockwave, restored his condition. As with the football case, the individual contribution of shockwave cannot be separated from the other treatments.
What shockwave cannot do
It cannot stabilize a subluxating tendon. Shockwave may be directed to symptomatic tendon tissue. It does not mechanically stabilize a subluxating tendon. It cannot correct retinacular failure, the shape of the fibular groove, intrasheath tendon switching or recurrent dislocation. When snapping or instability dominates, dynamic imaging and an orthopedic pathway may matter more.
It has no robust evidence for repairing tears. There are case-level reports of good outcomes when shockwave was part of conservative care for a peroneal tear, but no robust trial evidence showing that shockwave can repair or regenerate split tears or other peroneal tendon tears. Suspected tears are assessed with imaging first.
Why diagnosis comes first
Peroneal disorders span tendinopathy, tenosynovitis, tendon tears, stenosis and intrasheath subluxation. A recent systematic review of peroneal tendoscopy found these overlapping problems in patients with similar lateral ankle symptoms, and noted that some structural causes were under-recognized before surgery.
Imaging research is also more developed than the shockwave research. A 2025 meta-analysis of 12 studies found pooled ultrasound sensitivity of 93% for peroneus brevis tears and 94% for peroneus longus tears, although the studies were heterogeneous and at high risk of bias. Dynamic ultrasound can also show subluxation that static imaging misses. The full comparison is covered in peroneal tendinopathy vs. tendon tear or subluxation.
In practice, that means a patient with load-related pain, preserved strength and no snapping is in a very different position from one with reduced strength, persistent swelling or a reproducible click. Only the first fits the profile for an adjunctive tendon treatment without further investigation.
Who may be a candidate?
Shockwave may be considered when:
- The exam points clearly to peroneal tendinopathy as the pain generator
- Symptoms have persisted despite load management and progressive peroneal loading
- There are no features suggesting a substantial tear, or imaging has excluded one
- There is no snapping or subluxation, or instability has been assessed and managed
- There are no signs of nerve, ligament or bone pain that better explain the symptoms
It is used alongside progressive loading of eversion strength, plantarflexion control, single-leg balance and running or sport demand, not as a replacement for it.
What loading looks like alongside shockwave
Rehabilitation should progressively rebuild the peroneal tendons' ability to tolerate eversion, plantarflexion, single-leg loading and higher-speed lateral demand. Early on, that may mean resisted eversion and calf raises at a tolerable load, with temporary changes to the most provocative activities, such as cambered roads, technical trails or cutting drills. As symptoms settle, single-leg balance, hopping and running progress, followed by lateral movement, changes of direction and sport-specific drills. Pain during and after loading, and how the tendon feels the next morning, guide the pace. Complete rest is rarely the best default, because the goal is to restore the tendon's capacity rather than simply quiet it down. If shockwave is used, it sits within this program rather than replacing any part of it.
Radial or focused?
The 2026 football case used focused shockwave. No study has compared radial and focused shockwave for peroneal tendon problems, so neither is established as superior. Device choice depends on the location of tenderness and tissue depth. More on the general differences is in radial vs. focused shockwave.
What better evidence would look like
Useful future studies would compare progressive loading alone with progressive loading plus shockwave in patients with confirmed peroneal tendinopathy, use sham-controlled designs, and clearly separate tendinopathy from tears and instability. They would also report protocols in enough detail to be reproduced. Until then, shockwave for the peroneal tendons rests on biological plausibility, evidence from other tendons and a small number of case reports.
Where shockwave fits
Shockwave therapy is a reasonable adjunct to consider for selected persistent peroneal tendinopathy when the diagnosis is clinically convincing and major tear or instability has been excluded. The direct peroneal-specific evidence is still limited, however, and ESWT should not be presented as a substitute for progressive loading or as a treatment for mechanical tendon subluxation.
How Novo uses this evidence
We first decide whether the peroneal tendons are the source of pain and whether the picture fits tendinopathy, a tear or instability. Shockwave is one option for persistent tendinopathy within a plan built on progressive loading, with imaging or referral when a tear or instability is suspected. See how we approach peroneal tendinopathy, learn about radial shockwave and focused shockwave, or book a new patient exam.
