An assessment of the effectiveness of hyaluronic acid and polyacrylamide hydrogel in horses with osteoarthritis: Systematic review and network meta-analysis.
Abstract: For several years, hyaluronic acid (HyA) and, more recently, polyacrylamide hydrogel (PHyd) have been used to reduce lameness and pain caused by osteoarthritis. However, there is still a lack of scientific evidence of the efficacy of these substances to allow veterinary experts to make decisions about their use in horses. The objective of this study was to evaluate, through a systematic review and network meta-analysis (NMA), the efficacy of HyA, associated or not with other drugs, and PHyd in relieving lameness in horses with osteoarthritis. The searches for primary studies were conducted on four search platforms. The efficacy of HyA and PHyd was estimated through the relative risk difference method. Heterogeneity was observed in the efficacy of HyA, indicating long-term ineffectiveness of this drug when associated or not with anti-inflammatory drugs. In contrast, the results indicate that PHyd is an effective alternative therapy, with a long period of action in reducing lameness in horses with osteoarthritis. This study provides evidence that the application of PHyd and HyA is effective in reducing lameness caused by osteoarthritis in horses at different time periods, where PHyd has a longer time of action.

This research study evaluates the effectiveness of hyaluronic acid and polyacrylamide hydrogel in relieving osteoarthritis symptoms in horses. The study found that polyacrylamide hydrogel was a more effective long-term solution than hyaluronic acid.
Research Objective
- The main goal of this study was to analyze and compare the effectiveness of hyaluronic acid (HyA) and polyacrylamide hydrogel (PHyd) in relieving the lameness symptoms associated with osteoarthritis in horses. To do this, the researchers conducted a systematic review and network meta-analysis (NMA) on various studies available on four different platforms.
Methods
- The researchers estimated the efficacy of HyA and PHyd through the relative risk difference method. This involved comparing the risks associated with each treatment, measured as the difference in the proportion of horses that showed improvement after being treated with HyA or PHyd.
- Heterogeneity was examined within the study, indicating variations in the results of different studies on the effectiveness of HyA.
Findings
- The research found that both HyA and PHyd were effective in reducing lameness caused by osteoarthritis at different time scales.
- However, the effectiveness of HyA was found to be inconsistent, pointing out towards its long-term ineffectiveness, irrespective of it being administered alone or in conjunction with anti-inflammatory drugs.
- Conversely, the study found that PHyd acted as an effective alternative therapy, providing a longer period of effectiveness in reducing lameness symptoms in horses suffering from osteoarthritis.
Implications
- This study offers valuable scientific evidence on the efficacy of HyA and PHyd in treating osteoarthritis in horses, thereby aiding veterinary professionals in making more informed decisions regarding their use.
- The findings suggest that in terms of longevity and consistency of effectiveness, PHyd may be a more favorable treatment option compared to HyA for managing osteoarthritis symptoms in horses.
