Comparison of efficacy of intraarticular polyacrylamide hydrogel and methylprednisolone acetate in patients with knee osteoarthritis

Purpose: The aim of this study was to compare and evaluate the efficacy of intraarticular methylprednisolone acetate and an intra-articular polyacrylamide hydrogel in patients with different stages of knee osteoarthritis. Materials and Methods: Patients with symptomatic knee osteoarthritis and history of failed pharmacotherapy or physiotherapy interventions were included in this study. The first 64 consecutive patients got intra-articular polyacrylamide hydrogel, the latter 79 consecutive patients got intra-articular methylprednisolone acetate. Patients were evaluated by WOMAC score and self-assessment questions. Results: There was no statistically significance difference between groups when WOMAC scores and answers of self-assessment questions were compared. Conclusion: Intra-articular use of polyacrylamide hydrogel was not superior to methylprednisolone acetate, for patients with knee osteoarthritis.
