Tendinopathy: what actually helps and what to avoid
Tendinopathy is a field where the language was contested for years, and getting the words right turns out to matter for reading the evidence honestly. This guide starts with the ICON consensus that settled on tendinopathy as the preferred term for persistent, load-related tendon pain, then turns to the guidelines that agree progressive loading is the core treatment while most adjuncts remain uncertain. It draws on condition-specific guidance for the Achilles as a worked example, and on the studies we have appraised, from PRP mechanism reviews to lipid associations in plantar heel pain, to show how often promising ideas outrun the clinical evidence. It defines the key terms and answers the questions clinicians hear most. The recurring theme is that loading and patience have the strongest support, and that passive quick fixes tend to be oversold.

Foundations: consensus & guidelines
The international consensus statements this topic is built on. Start here, then read the appraised studies below against them.
A graded clinical practice guideline, linked to the ICF, on the assessment and management of midportion Achilles tendinopathy characterised by pain, stiffness and muscle power deficits.
- Supports clinical diagnosis and outcome measurement rather than routine imaging.
- Grades mechanical loading exercise, including eccentric and heavy slow resistance, as the best-supported core treatment.
- Recommends patient education and load management, with many adjunct treatments carrying weaker evidence.
Our appraisal: A rigorously constructed guideline that grades the strength of each recommendation, which is its main value; the strongest recommendations sit behind loading exercise, while many popular adjuncts are graded on lower-certainty evidence and should be treated as optional.
Read the statement ↗An evidence-based multidisciplinary guideline covering risk factors, diagnosis, imaging, treatment and prognosis of Achilles tendinopathy, developed with patient involvement.
- Midportion Achilles tendinopathy is a clinical diagnosis based on load-related pain localised about 2 to 7 cm above the insertion, local thickening and pain on palpation, and imaging is not required to make it.
- Progressive exercise, or loading, is recommended as the core first-line treatment.
- Injections and surgery are reserved for cases that do not respond to an adequate course of loading.
Our appraisal: A formal multidisciplinary guideline with patient participation, so its diagnostic framework is trustworthy; many of its treatment recommendations rest on low-certainty evidence, so it is firmer on how to diagnose and structure care than on the comparative efficacy of specific protocols or adjuncts.
Read the statement ↗International consensus (ICON) standardising terminology for tendinopathy in research and practice.
- Recommends tendinopathy as the preferred term for persistent tendon pain and loss of function related to mechanical loading.
- Discourages routine use of tendinitis and tendinosis, since inflammation is not the dominant feature of most chronic presentations.
- Calls for consistent terminology to make research and clinical communication comparable.
Our appraisal: A terminology consensus reached by expert agreement, so it standardises language rather than validating any treatment; its practical value is that it lets you read the tendon literature consistently and steers management away from an inflammation-first framing towards loading.

Key terms in this topic
Frequently asked
Why does the terminology matter, tendinitis versus tendinopathy?
The ICON consensus recommends tendinopathy as the default term for persistent tendon pain and loss of function related to mechanical loading, and discourages tendinitis as a routine label because inflammation is not the dominant feature in most chronic cases. This is not pedantry: consistent terminology lets you compare studies that would otherwise be talking past each other, and it steers management away from an inflammation-first mindset towards loading.
What is the first-line treatment for tendinopathy?
Progressive mechanical loading. Guidelines across tendon sites converge on structured, graded exercise as the core intervention, with education and load management alongside it. Passive treatments and injections sit in an adjunct role with weaker and less consistent evidence. The specific loading recipe, eccentric versus heavy slow resistance for example, matters less than doing sufficient progressive load consistently over time.
Does platelet-rich plasma help tendinopathy?
The biological rationale is plausible, which is why PRP keeps being offered, but that is not the same as clinical benefit. Our appraisal of a widely cited PRP review made exactly this point: it explains the mechanism, not whether the injection helps your patient. PRP is not a first-line treatment for tendinopathy, and its clinical evidence remains weak and inconsistent.
Do I need a scan to diagnose tendinopathy?
Usually not. Tendinopathy is a clinical diagnosis based on load-related pain and local signs, and imaging findings correlate poorly with symptoms, so structural changes on ultrasound or MRI are common in pain-free tendons. Imaging is most useful to exclude other diagnoses rather than to confirm tendinopathy or to track treatment.
How long does tendinopathy take to settle?
Often longer than patients hope, typically weeks to months of consistent loading, and setbacks are normal. Managing expectations is part of the treatment. Be sceptical of any intervention promising a rapid cure, because the natural course is slow and the strongest evidence is for patient, progressive load rather than a passive shortcut.
