Purpose: To evaluate if High-volume Image-guided Injection (HVIGI)-treatment for chronic mid-portion Achilles tendinopathy (AT) improve function and reduce pain at 12-months follow-up. Methods: Patients with resistant mid-portion AT who failed to improve after a three-month eccentric loading program were included in the study. Maximal tendon thickness was assessed with ultrasound. All patients were injected with 10 mL of 0.5% Marcaine, 0.5 mL Triamcinolonacetonid (40 mg/mL) and 40 mL of 0.9% NaCl saline solution under real-time ultrasound-guidance and high pressure. All outcome measures were recorded at baseline and 12 months. A standardized eccentric rehabilitation protocol was prescribed after HVIGI-treatment. Clinical outcome was assessed with the Victorian Institute of Sports Assessment-Achilles tendon questionnaire (VISA-A) and statistically analyses were performed. Results: The study included 30 single treatment HVIGI procedures in AT in 28 patients (23 men, 5 women) with a mean age of 45.1 (range 16–63). The mean duration of symptoms before HVIGI was 37 months. The baseline VISA-A score of 50 ± 15 (range 14–74) improved to 61 ± 21 (range 31–94) after 1 year (p = 0.04). Of the 30 AT procedures 10 patients (11 AT) were not satisfied after the initial HVIGI procedure. Of these, 8 patients (9 AT) needed additional HVIGI and two patients needed surgery. Of the remaining 18 patients (19 AT), 10 patients had more than a 10-point improvement in the VISA-A score after 1 year. Conclusions: In this retrospective case-study, only 10 patients (33%) did benefit of a single HVIGI treatment at 12-months and an 11-point significant improvement was seen at on the VISA-A score.
