Joint injection
Intra-articular hip injections have both a therapeutic and diagnostic utility in the management of hip disorders. Intra-articular local anaesthetic injections, especially with image guidance, can help delineate an intra-articular versus extra-articular versus spinal source of hip symptoms and has a high positive predictive value for successful surgery. With respect to intra-articular hip biologics, the most widely studied medications are corticosteroids, HA and PRP. In the setting of OA, corticosteroids appear to be the most effective, providing significant pain relief for up to 12 weeks.
