Resumen
GARCIA-BRAVO, AM et al. Single eco-guided intra-articular injection of hyaluronic acid in symptomatic coxarthrosis: retrospective study of the efficacy of two presentations. Rev. Soc. Esp. Dolor [online]. 2022, vol.29, n.3, pp.140-148. Epub 20-Mar-2023. ISSN 1134-8046. https://dx.doi.org/10.20986/resed.2022.4014/2022.
Introduction:
Ultrasound-guided viscosupplementation with hyaluronic acid in symptomatic hip osteoarthritis is widely used as a safe treatment with proven efficacy, although there is a lack of consensus on its use as routine practice. Few studies have compared the efficacy of two single injection products.
Objetive:
To evaluate the efficacy in infiltrated patients with two single injection hyaluronic acids comparing Adant One® (A) at six months with annual Hyalone® (H).
Material and method:
Restrospective observational study on a cohort of patients with symptomatic hip osteoarthritis, treated by ultrasound-guided intra-articular viscossuplementation with two types of single injection of hyaluronic acid. Its efficacy was evaluated according to the WOMAC and VAS scales at 6 and 12 months.
Results:
144 patients were treated with a single dose of A and 84 with H. At 6 months, those treated with A showed improvements in relation to pain reduction in the VAS (p < 0.001) and in the WOMAC pain (p = 0.003), as well as in global WOMAC (p = 0.027). There were no changes in WOMAC stiffness and function. At 12 months, those treated with H showed significant improvements in the VAS (p < 0.001) and global WOMAC (p = 0.010) parameters and in all their dimensions.
Conclusions:
A single injection of annual H was more effective in improving pain and function of the hip with osteoarthritis at 1 year compared to A at 6 months. It is possible to establish annual viscossuplementation protocols for hip osteoarthritis with hyaluronic acid using H.
