    In a randomised, controlled, clinical trial comparing corticosteroid injection, eccentric training and heavy slow resistance training for patellar tendinopathy, heavy slow resistance training had both (1) good clinical effects and (2) pathology improvement and increased collagen turnover

    Background

    There are a number of treatment modalities for patellar tendinopathy, including corticosteroids, eccentric training and heavy slow resistance training

    Research question/s

    What are the clinical, structural and functional effects of three treatment modalities (peritendinous corticosteroid injections (CORT), eccentric decline squat training (ECC) and heavy slow resistance training (HSR)) in patients with patellar tendinopathy?

    Methodology

    Subjects 37 patients with patellar tendinopathy (males)

    Experimental procedure All the subjects were assessed (including (1) function and symptoms—VISA-p questionnaire, (2) tendon pain during activity (VAS), (3) treatment satisfaction, (4) ultrasonography—tendon swelling and vascularisation and (5) tendon mechanical properties and collagen crosslink). Thereafter, subjects were randomised to one of three treatment modalities (CORT, ECC, HSR) for 12 weeks. Repeat measures were done at 12 weeks and at a 6-month follow-up

    Measures of outcome VISA—p score, pain (VAS), swelling (%), mechanical properties, collagen crosslink, treatment satisfaction

    Main finding/s

    Mechanical properties Mechanical properties were not affected by treatment

    Collagen crosslink An elevated collagen network turnover was demonstrated in the HSR group …
