CLINICAL EXPERTISE
Transarterial Microembolization for Musculoskeletal Pain (TAME)
Minimally invasive embolization for selected chronic musculoskeletal pain conditions
TAME is an endovascular intervention developed for selected patients with chronic, refractory musculoskeletal pain. Clinical history, physical examination, and imaging are integrated before angiography is used to identify abnormal microvascular signals around the symptomatic lesion. TAME is not a first-line treatment for every pain condition, and eligibility should never be decided from a single image alone.
KEY TAKEAWAY
Bottom line
Current evidence suggests potential benefit for knee osteoarthritis, adhesive capsulitis, and selected tendinopathies, but much of the literature still consists of single-arm studies or case series. The key question is not simply whether embolization can be performed; it is whether the patient’s symptoms, target lesion, and abnormal vascular signal are concordant, while infection, fracture, tumor, instability, and conditions requiring surgery have been appropriately excluded.
Who may benefit from further assessment?
- Persistent pain that interferes with activity, sleep, work, or daily function.
- Limited response to appropriate medication, rehabilitation, activity modification, or injection therapy.
- Concordance among symptoms, focal tenderness, and imaging findings.
- A clinical and imaging pattern suggesting chronic inflammatory neovascularity around the pain generator.
- Willingness to attend follow-up and continue rehabilitation or other treatment when indicated.
What is integrated during assessment?
- Define the primary pain location, provoking movements, disease course, and response to previous treatment.
- Use radiography, ultrasound, MRI, or MRA according to the anatomical region and clinical question.
- Determine whether pain is predominantly related to a joint, tendon, ligament, bone marrow lesion, nerve, or postoperative tissue.
- Discuss conventional angiographic treatment, simplified approaches, and nonvascular alternatives when appropriate.
Situations requiring individualized assessment or a different priority
This list is not intended for self-diagnosis. Acute or rapidly worsening symptoms should be evaluated promptly so that urgent causes can be excluded.
- Uncontrolled local wound infection, acute infection, or systemic infection.
- Coagulopathy or antiplatelet/anticoagulant therapy that has not undergone individualized risk assessment.
- Severe renal impairment, contrast allergy, or peripheral arterial disease requiring a modified strategy.
- Pregnancy or possible pregnancy, requiring assessment of radiation and contrast-related risks.
- Fracture, tumor, infection, marked instability, or another condition that should be treated first.
From diagnosis to follow-up
- 01Clinical assessment: establish the pain generator and review prior imaging and treatment.
- 02Procedure planning: select the vascular access, image-guidance method, and embolization strategy.
- 03Targeted treatment: identify and selectively treat abnormal microvascular signals.
- 04Follow-up: document pain, function, imaging changes when relevant, and adverse events.
How should the evidence be interpreted?
| Source | Study or data type | Practical interpretation |
|---|---|---|
| 2021 systematic review | 7 studies and 4 abstracts | Signals of pain and functional improvement were reported for knee osteoarthritis, adhesive capsulitis, and several tendinopathies. Study heterogeneity was substantial, and randomized trials remain necessary. |
| 2025 adhesive capsulitis meta-analysis | 12 single-arm studies; 329 shoulders | Pain, range of motion, and functional outcomes improved during follow-up. Technical success was 100%, and no major adverse events were reported in the included literature. |
| Bow Wang research team, 2026 | TAME compared with arthroscopic capsular release | Some pain and clinical improvement measures favored TAME at three months; between-group differences were not evident at six months, supporting individualized treatment selection. |
| 2024 complications review | Review of clinical challenges and management | Potential complications include vascular perforation or dissection, access-site bleeding, arterial injury, and tissue ischemia. Pre-procedure planning and follow-up are essential. |
Published results describe group-level outcomes under specific eligibility criteria and do not predict an individual result. Disease type, embolic material, technique, and follow-up duration can all influence outcomes.
