Percutaneous Electrolysis Techniques in Tendinopathy Management

Percutaneous electrolysis has emerged as a minimally invasive intervention for chronic tendon disorders characterised by pain, impaired function and degenerative change. Under ultrasound guidance, a fine‐gauge needle is introduced into the pathological tendon region and a controlled low‐intensity galvanic current is applied. This electrical stimulus induces a targeted microtrauma that triggers a local pro‐inflammatory cascade, cell apoptosis in degenerated tissue and subsequent modulation of extracellular matrix remodelling. The resulting environment synchronises collagen synthesis, neovascularisation and resolution of chronic degeneration. Clinicians often integrate percutaneous electrolysis with an eccentric exercise programme to optimise tendon loading and promote long‐term tissue adaptation. This combined approach has been translated to a range of sites including the lateral epicondyle, supraspinatus, patellar tendon and Achilles, demonstrating consistent improvements in pain thresholds, functional capacity and tendon morphology on imaging. Global adoption has been driven by its favourable safety profile, reproducibility under ultrasound and potential to reduce reliance on pharmacological or more invasive surgical interventions. Ongoing refinements in needle design, current dosage and guidance techniques aim to enhance precision and individualise treatment protocols for diverse clinical presentations.

Technical terms

Percutaneous electrolysis: An ultrasound-guided technique in which a needle delivers a galvanic current into targeted tendon tissue to induce controlled local inflammation and stimulate healing.

Galvanic current: A continuous direct electrical current used in electrolysis interventions to provoke cellular and extracellular responses.

Tendinopathy: A clinical syndrome of tendon pain, swelling and impaired function associated with microstructural degeneration and failed healing.

Eccentric exercise: A rehabilitative loading strategy in which the muscle-tendon unit lengthens under tension to promote tissue adaptation.

Extracellular matrix remodelling: The dynamic process of degradation and synthesis of collagen, proteoglycans and other matrix components during tissue repair.

Ultrasound guidance: Use of real-time sonographic imaging to visualise needle trajectory and anatomic structures for precise intervention.
