PRP or cortisone for hip osteoarthritis
Cortisone is the more predictable option for hip osteoarthritis when the goal is short-term relief of a flare, with benefit usually lasting up to about 12 weeks and no clear advantage by 6 months. PRP sits outside routine care and is more often considered in earlier or mild-to-moderate disease; evidence is mixed, with some trials favouring it over hyaluronic acid while a placebo-controlled trial in grade 2 or 3 hips found no meaningful difference from saline. Neither injection is cartilage regrowth, neither reliably fixes advanced bone-on-bone arthritis, and the choice depends on speed of relief, stage of disease, tolerance for uncertainty and the recovery plan.
