hock injuries

My 16 year old ottb had a hock injury on the track which has created arthritis and some lameness. We have done hock injections and he didn’t really respond as much as we hoped for. Does anyone know of a way to keep his arthritis less inflamed and a little more comfortable for him? I was looking into the vibe hock boots, does anyone know if those help?

That may be better addressed if you post it in the Horse Care forum, where horse health is discussed.
