Editorial Commentary: Intra-articular Injection for Osteoarthritis-Is It Hip or Not?

Intra-articular injections are commonly used in the treatment algorithm for osteoarthritis of the hip. A number of different adjuvants can be used, such as corticosteroids, hyaluronic acid, and platelet-rich plasma, but there is no consensus regarding indications for or anticipated outcomes of each of these interventions. Recent data suggest that corticosteroids provide the best relief in the short term whereas platelet-rich plasma may be more beneficial in the mid term, but the results are variable. Ultimately, more rigorous studies are needed to evaluate these adjuvants, in particular biologics, while remaining fastidious with our indications for injection therapy.
