THE EFFECTS OF INTRATENDINOUS AND RETROCALCANEAL INTRABURSAL INJECTIONS OF CORTICOSTEROID ON THE BIOMECHANICAL PROPERTIES OF RABBIT ACHILLES TENDONS

Abstract

Local injections of corticosteroid, both within the tendon substance and into the retrocalcaneal bursa, adversely affected the biomechanical properties of rabbit Achilles tendons. Additionally, tendons from rabbits that had received bilateral injections of corticosteroid demonstrated an additive adverse effect, with significantly worse biomechanical properties compared with tendons from rabbits that had received unilateral injections of corticosteroid.
