What is the most appropriate treatment for patellar tendinopathy?

Two further studies on pharmacological interventions for tendinopathies were found. These studies compared the injection of tropisetron (a highly selective inhibitor of the 5HT3 receptor which may inhibit release of substance P and other neurokines) with corticosteroid injection (no patellar tendinopathy cases included) (1) and local anaesthetic (2). It is unclear if the study that compared local anaesthetic to tropisetron included subjects with patellar tendinopathy, as the category reported was ‘tendopathies and periarthritis genu’. Both studies were randomised, tropisetron showed better pain reduction at 3 days compared to local anaesthetic and similar outcome to corticosteroid injection at 3 months. The followup period for both studies was very short, and needs to be extended especially if comparing results to corticosteroid injection.
