Efficacy of intraarticular hyaluronic acid injection through a lateral approach under fluoroscopic control for advanced hip osteoarthritis.

OBJECTIVES Hyaluronic acid (HA) is used for intraarticular treatment of hip osteoarthritis (OA). The objective of this study was to determine the efficacy of intraarticular injection of HA through a lateral approach under fluoroscopic control for advanced hip OA. METHODS The study included 21 patients with advanced hip OA. All patients received 2.5 ml HA injection once a week for 3 weeks by lateral approach under fluoroscopic control. Disability (Lequesne index), pain scores (visual analog scale-VAS) and analgesic use of patients were assessed before treatment and 1, 3 and 6 months after the treatment. RESULTS Lequesne index and VAS pain scores measured 1, 3 and 6 months after treatment were significantly lower compared to baseline scores (p<0.001). Although analgesic use was significantly reduced 1 and 3 months after treatment compared to baseline (p<0.05), no difference was determined in analgesic use at the 6th month (p>0.05). No side effect was observed. CONCLUSION In conclusion, intraarticular HA injection through a lateral approach under fluoroscopic control was shown to be a safe and effective method for patients with advanced hip OA.
