    • Abstract:
      Background: Osteoarthritis (OA) is the most prevalent form of joint disease and commonly affects the hip. Hip OA is associated with a high socioeconomic burden. Intra-articular hyaluronic acid (HA) injection may be of benefit but quality evidence for HA use in hip OA is lacking. The purpose of this study was to assess the safety and efficacy of ultrasound guided injection of a high molecular weight, non-animal derived, stabilised HA (NASHA) in patients with mild to moderate hip OA.
      Methods: This single site study is an analysis of prospectively collected outcome data for 87 consecutive patients over a 2-year period who received a single HA (Durolane) injection for symptomatic hip OA. Inclusion criteria were male or female patients over 18-years of age with mild to moderate hip OA on x-ray. Patients with severe hip OA were excluded. The primary outcome measure was a modified Harris Hip Score (mHHS) questionnaire at baseline and 6-weeks with a minimal clinically important difference (MCID) of 10 points. All adverse events were recorded and assessed.
      Results: Data from 87 patients, 49 women and 38 men with mean age of 54 (SD = 10.8) were analysed. At baseline, mean mHHS was 58.47 (SD 14.31). At the 6 week follow up, mean mHHS improved to 71.30 (SD 16.46), a difference of 12.83 (p < 0.01). This was greater than the MCID of 10. No significant adverse events were encountered. Five patients reported short-lived injection site pain.
      Conclusion: A single injection of HA (NASHA) in the setting of hip joint OA was both safe and efficacious in this 87 patient cohort. Improvement in pain and function as measured with mHHS was statistically significant and reached the MCID of 10.
      Trial Registration: The study was retrospectively registered on the 1st of February 2021 in the Australian New Zealand Clinical Trials Registry with registry number ACTRN12621000098831 . All research was performed in accordance with the Declaration of Helsinki.
