Abstract
OBJECTIVES: The aims of this study were to determine the risk of septic arthritis after intra-articular medication (IAM) and to identify potential risk factors for this complication. DESIGN: A retrospective and prospective descriptive study of prevalence, and matched case-control study for risk factors. RESULTS: Of 16,624 joints injected in 1103 horses at 6695 horse-visits, septic arthritis occurred as a complication in 13 joints (13 horses). The risk of septic arthritis following IAM was 7.8 cases per 10,000 injections or 1 case per 1279 injections. Veterinarian and type of corticosteroid were identified as risk factors. CONCLUSIONS: Septic arthritis is an uncommon complication of IAM in horses, yet the risk is substantially higher than that reported in humans. The risk was higher for some veterinarians; identifying the reason for this was beyond the scope of this study, yet we presume they may have paid less attention to strict aseptic technique. A larger study may be needed to clarify whether the risk is greater with certain types of corticosteroids and to identify additional risk factors.
