Viscosupplementation for Hip Osteoarthritis: A Systematic Review and Meta-Analysis of the Efficacy on Pain and Disability, and the Occurrence of Adverse Events.
This Systematic Review was published in 2018 in Journal of Arch Phys Med Rehabil. (IF 2018: 1.93) by Brazilian specialists. The aim of this study was to assess the efficacy of viscosupplementation (hyaluronic acid [HA]) on the pain and disability caused by hip osteoarthritis, and to determine the occurrence of adverse events.
We do not recommend viscosupplementation for hip osteoarthritis. Compared with placebo, data show scarce evidence of its efficacy up to 3 months, and suggest no difference at 6 months. However, future RCTs could present HA as an alternative to methylprednisolone for short-term symptom relief.
