Core Tip

Core Tip: This study investigates, through network meta-analyses, the effectiveness of different sub-acromial injections for rotator cuff injuries. The main findings include that hyaluronic acid (HA) offers the best short-term pain relief, while HA combined with platelet-rich plasma shows the most significant functional improvement in the medium and long terms. None of the interventions sustained pain relief beyond three months. These results provide critical insights for optimising therapeutic strategies for rotator cuff injuries.
