Methods
Twenty-five osteoarthritic hip joints in 22 patients were selected for study from the patient population at the rehabilitation clinic at our institution from 1998 to 2000. The demographics included 14 men and 11 women, with a mean age of 56.4 years (range, 39–72y). Inclusion criteria were demonstration of hip OA on plain radiography and magnetic resonance imaging (MRI) and failure of all conservative methods, including physical therapy, anti-inflammatory medications, and fluoroscopically guided
Results
The mean AAOS Lower Limb Core Scale score improved from a preinjection mean of 44.2 (range, 29.1–57.2) to a follow-up mean of 86.1 (range, 71.3–99) (P<.05). Mean visual numeric pain score improved from a preinjection mean of 8.7 (range, 6.4–10) to a follow-up mean of 2.3 (range, 0–7.2). The overall success rate was 84%.
In patients with mild to moderate OA, the mean pain score decreased from a preinjection value of 7.8 to a follow-up value of 1.7. The success rate was 90.5%.
In patients with
Discussion
Hyaluronic acid is an integral part of the connective tissue system. In synovial joints, it forms an important component of the synovial fluid, which contributes to its viscosity, protection of the superficial layer of articular cartilage, and mechanical shock absorption.5
These properties led to the favorable results of intra-articular injections of hyaluronic acid in osteoarthritic knees.2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 Results of hyaluronic acid substitutes like hylan G-F 20 have been quite
Conclusion
Hyaluronic acid compounds such as hylan G-F 20 may benefit select patients with mild to moderate OA of the hip joint, when combined with a structured exercise regimen. More studies, including randomized controlled trials, are required to further substantiate the efficacy of this form of treatment.

Is Intra-Articular Hyaluronic Acid Effective in Treating Osteoarthritis of the Hip Joint?
2015, Journal of ArthroplastyCitation Excerpt :Twenty-three of 286 manuscripts met the overall inclusion criteria for this study (Fig. 1). Overall there were six prospective randomized controlled trials [3–8] (Level 2), fifteen prospective studies [9–23] and two retrospective studies [24,25] (Table 1). We assessed each study to determine if they were either retrospective or prospective and we assessed the overall power of each study to determine quality.

2009, PM and RCitation Excerpt :Intra-articular administration of HA has been used for degenerative osteoarthritis for more than 35 years. Injection of HA has demonstrated safe and effective results in the hip [28], knee [29], ankle [30], sacroiliac [31], and, more recently, patellofemoral joint [32]. However, other than in the arthritic knee, its use in these joints is off-label.
