Of 197 respondents, 160 completed the survey, forming the basis for the descriptive statistical analysis. The primary indications for polyacrylamide gel use were chronic synovitis/osteoarthritis (87.1%) and failure of prior joint treatment (83.6%). Treatment protocols, post-treatment rehabilitation plans, and clinical outcomes varied among practitioners and respondent groups based on experience and disciplinary focus (assessed using automated A/B or Kruskal-Wallis with post-hoc Dunn’s test). Most respondents reported return to full exercise from week 4 post-treatment. Complications, worsening, or lack of improvement following treatment were rare, while complete recovery, partial improvement, or transient improvement were commonly observed. Median satisfaction score among respondents was rated 8/10. As expected with the study design, the responses limited detailed insights into individual experiences and may reflect response bias, with most respondents being specialized or focused on equine orthopedics. Despite these limitations, the survey highlights a general good satisfaction with intra-articular polyacrylamide gel, mainly for chronic synovitis/osteoarthritis and use after failure of prior joint treatment, with low reported complication rates and favorable outcomes.
