Abstract: Purpose: The purpose of this work was to investigate the efficiency of intra-articular injection of hyaluronic acid (HA) under ultrasound (US) guidance as a symptomatic treatment of hip osteoarthritis (OA).
Methods: This prospective clinical work was performed on 21 individuals aged more than 35 years old, both sexes, with clinical criteria of OA hip, failed medical treatment for pain after one month using nonsteroidal anti-inflammatory drugs (NSAIDs) for primary hip OA and secondary hip arthritis in avascular necrosis and Kellgnen-lawrence criteria I – II – III classification of hip OA. All patients in the study were subjected to radiological investigations (x-ray pelvis antro-posterior view) showing both hips.
Results: Cases were categorized into excellent group (n = 17) and good group (n = 4). The results were significantly affected by age, weight, and BMI and pre procedural times of NSAID consumption /day and not affected by sex, height, comorbidities, laterality, Kellgnen-lawrence criteria. NSAID consumption had been substantially decreased in the excellent group than good group. The number of patients who required NSAID and NSAID intake, In comparison to baseline, the amount of individuals with pain, the Harris Hip Score (HHS) and the visual analogue scale (VAS), had all been considerably reduced at the three- and six-month scores.
Conclusions: injection of HA intra-articular via ultrasound-guided is an effective and safe treatment for manifested hip OA.
