Intra-articular, single-shot co-injection of hyaluronic acid and corticosteroids in knee osteoarthritis: A randomized controlled trial.

ABSTRACT: The aim of the present study was to investigate whether the co-injection of hyaluronic acid (HA) and corticosteroids (CS) was superior to HA alone in the treatment of knee OA. A total of 120 participants with symptomatic knee OA were recruited and formed the intention-to-treat population for a 6-month follow-up. In the HA group, patients received a single-shot injection of 4 ml HA. In the HA&CS group, patients received a co-injection of 3 ml compound betamethasone solution and 4 ml HA. Visual analog scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and knee flexion motion were assessed as primary outcomes. Patients in the HA&CS group exhibited better pain relief and knee function at the time points of week 1, month 1 and month 3 (P<0.05). For the last follow
