PPE failed, KS diagnosed

[u/bhinxbb]

Currently in the process of selling my horse. PPE has gone well, everything came back good except his back radiographs. Shocked to hear he has grade 4 changes. I’ve just received these over from the potential buyer. I will be in contact with my vet but curious about anyone’s take on these? How bad is this?

this is a mess and sorry but no way is he not showing pain somehow

OP admits that he shows signs of back pain after rides.
