FAQs

Arthramid® Vet

• Have you seen any adverse reactions following the intra-articular injection of Arthramid® Vet?

  We have not seen any abnormal reaction in the joints in the research population. However, we allow the veterinarians involved in the field trial to use antibiotics simultaneously with Arthramid ® Vet. There are a few reported cases of granulomatous reactions when PAAG has been used concurrently with corticosteroids. Horses in this study must have no other treatments within 4 weeks of administration.

• Does the articular treatment need to be repeated at a specific interval or 1 dose is enough?

  One dose is often enough but this is something we are wanting to find out. Anecdotally repeating the dose either at 4 weeks for partial responders or at 6 months has been beneficial.

• If horse does not improve, what is the course of action?

  We recommend trying to understand why it didn’t work (further imaging, synovial fluid, other factors ( e.g. foot imbalance, conformation, work surface)...etc...). This is different from horses that are partial responders. These horses should be re-examined at 4-6 weeks and another dose administered as there is strong evidence that the mechanical effect is dose-dependent. This is another aim of this study.

• Can horses have some NSAID or other anti OA medications concurrent with Arthramid® Vet?

  NO NSAID, corticosteroids or other anti-OA medication should be injected.

• Do you need synovial fluid from the joints, and if so, in any specific tube?

  The synovial fluid can be put into sterile EDTA tubes and frozen at -20 degrees for up to 6 months. If collected, please let us know as we can arrange testing at a later date.

• Is it ok to inject several OA joints in the same horse?

  In the field trial, several joints can be injected in the same horse.

• Any trials on horses with no visible arthritis but blocking to joint with suspicion of sub-chondral bone damage and or stress fractures?

  AV is indicated for horses with a proper diagnosis of OA. If these horses show signs of sub-chondral damage, we think that we can also treat such cases with Arthramid® Vet.

• Is Arthramid® Vet indicated for osseous cyst-like lesions?

  Practitioners have reported good results on cases with osseous cyst-like lesions in the stifle and fetlock.
