Background High volume injection (HVI) shows promising results in the treatment of chronic midportion Achilles tendinopathy (AT). HVI consists of a large volume of saline with a small amount of corticosteroid and local anesthetic. Objective To determine the effect of corticosteroid in HVI in AT. Methods A total of 28 men (18‐59 years) with chronic (>3 months) AT were included in a double‐blinded RCT and followed for 24 weeks. All performed eccentric training and randomized to either (a) HVI injection with corticosteroid or (b) HVI injection without corticosteroid. Outcomes included self‐reported function (VISA‐A score) and pain (VAS score) and ultrasound imaging (tendon thickness, Doppler flow). Results VISA‐A and VAS score improved in both groups at all time‐points ( P < 0.05). VISA‐A improvement was significantly greater in HVI with corticosteroid (mean ± SEM; 6‐weeks = 31 ± 3 points; 12‐weeks = 32 ± 5 points) vs HVI without corticosteroid (6 weeks = 14 ± 3; 12‐weeks = 17 ± 3) at 6 and 12 weeks ( P < 0.05), but not at 24 weeks. Decrease in VAS scores was significantly greater in HVI with corticosteroid (6 weeks = 55 ± 3 mm; 12 weeks = 53 ± 5 mm) vs HVI without corticosteroid (6 weeks = 16 ± 3 mm; 12 weeks = 25 ± 5 mm) at 6 and 12 weeks ( P < 0.05) but not at 24 weeks. Tendon thickness decreased significantly in both groups at all time‐points ( P < 0.05), but more in the HVI with corticosteroid vs HVI without corticosteroid at 6 and 12 weeks ( P < 0.05) but not at 24 weeks. Conclusion High volume injection with or without corticosteroid in combination with eccentric training seems effective in AT. HVI with corticosteroid showed a better short‐term improvement than HVI without corticosteroid indicating a short‐term effect of corticosteroid in HVI treatment of AT.
