First of all, have the stitches held? If they are holding and the wound does not break open, I would leave it alone and wrap or bandage it according to what the Vet the sewed it up instructed. I would keep ALL topicals off of it as long as the stitches are holding.
That said, my experience with sewing up wounds below the knee or hock is that the stitches hold for a few days and then the wound breaks open and you have a bigger open wound to heal up that you would have had if you did not sew it up in the first place. It took me several years and several failed Vet stitching jobs to figure this out. I think I just wanted, so badly, for it to work. In reality, almost none of them did.
Wounds below the knee or hock tend to get a lot more proud flesh in them. You have to have some proud flesh to close up the gap in the skin on an open wound. Proud flesh is nature's band-aid. You have to have a little of it to fill in the gaps and to cover the exposed bones and tendons in a deep would.
So, in the beginning, I will thoroughly clean the wound ONE TIME an one time only. Then, I NEVER put water on it again -- ever.
When it is clean, I dry it with a paper towel and I put on some DMSO with a daubber and then I put Furacin Salve on the fresh wound and keep it wrapped. I will keep it wrapped, changing it daily for 2 or 3 days and then going to every 3 days.
When the gaps are filled in, I do not use Furacin any more. It promotes proud flesh and once there is enough of it to close the gaps and cover the underlying tissue, I work on getting it actually heal.
If it is summer and the flys are bad, I will use Underwoods' and baking powder because the flies stay off of it. Whenever I see any proud flesh protruding beyond the level of the skin I put 'Prouds Off' on it and let it 'eat' it back down to the skin level.
When it is dry and scabby, i put an unmedicated salve on it to keep it soft. I will alternate between the 2 or 3 things until the wound almost disappears and then I just keep a salve like 'Udderly Smooth' on it to help it hair back up.
When I started using DMSO on fresh wounds, I quit having any problems with infection. It also reduces the inflammation and swelling that can be so severe. Underwoods on a flesh wound also stops really huge wounds from getting infected. I do not know why, but bacteria cannot seem to be a toe-hold with either DMSO or Underwoods.
Deep wounds and puncture wounds always call for a Tetanus shot (anti-toxin). I keep a big bottle of it in the fridge.
