Hyaluronic acid compared with corticosteroid injections for the treatment of osteoarthritis of the knee: a randomized control trial
Springerplus. 2016 Apr 12;5:442140 patients with Kellgren-Lawrence grade II-III knee osteoarthritis were randomized to a single intra-articular injection of either corticosteroid or hyaluronic acid.

All other measures at all time points demonstrated no significant difference between groups.
