Efectividad y seguridad de la viscosuplementación con dosis única de ácido hialurónico estabilizado de origen no animal (NASHA) para el tratamiento del dolor secundario a gonartrosis

摘要

Objective: to evaluate the effectiveness and safety of single-dose injection of stabilized hyaluronic acid of non-animal origin (NASHA) for the treatment of pain related to knee osteoarthritis. Material and methods: we included a total of 37 patients with previously diagnosed gonarthritis by the Orthopedist/Rheumatologist in which conservative treatment has failed and/or who are not candidates for surgery. They carried out a single-dose injection of non-animal stabilized hyaluronic acid (Durolane?). We collected demographic data, adverse effects and pain intensity (assessed by verbal numeric scale) and scores on the questionnaires Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Barthel -baseline, at 2 weeks, at 3 months and 6 months of infiltration-. It has been considered effective a decrease ≥ 30% for more than 3 months at baseline scores. Results: patients are predominantly female (83.8%) with a mean age of 72.8 years (standard deviation = -S-8.4) and mean body mass index (BMI) 31.9 (S = 6.9). The left knee is infiltrated in 51.7%, 41.4% right and bilateral in 6.9% of patients. Adverse effects have occurred as well tolerated arthralgia 11.1% of patients. Based on the results, the infiltration with single dose of stabilized hyaluronic acid of non-animal origin for osteoarthritic source gonalgia caused a statistically significant reduction in pain intensity (numerical verbal scale and WOMAC) and functional capacity (WOMAC) at all measured intervals. There has been a ≥ 30% reduction in pain intensity in 54% (value that matches the reduction in WOMAC pain score) in 62.1% stiffness and functional capacity in 48.6% of patients. Conclusion: in our patients, intra-articular viscosupplementation single dose of stabilized hyaluronic acid of non-animal origin (NASHA, Durolane?) for the treatment of pain related to gonarthritis has been effective and safe and is a weapon for the management of pain and disability gonarthritis generated.
