A close idea…
My first suggestion is search pubmed.com with said surgery name and read the abstracts…
Closest in my experience is a stabilization procedure. You made the comment about a debridement…that is a very different animal so I’ll go with the “what if” should they find something different when they open you up…
There is some loss of “plantar flexion/eversion strength”, which in the system of riding would bias you toward, heels down (which you are doing and should continue to do so after surgery) and ankle roll out. A good stiff boot and regular off horse balance/strength training should also help minimize.
Your rehab professional should be able to help you establish a sufficient program.
On horse consideration…
Wider stirrup with a cavalry foot position.
Outside branch of the stirrup going back or no worse than straight out from the horse.
Horse should be narrow…Meaning when sitting on your saddle that is on the horse, your hips should be no wider than say 25 degrees abducted.
Let your toes point out to where your hips put them. If they are at 10/2 for example, let them stay there. Turning them forward and or doing something that precipitates the sole of the foot turning up should be avoided.
No knee blocks, don’t want to promote knee gripping.
The time frame is generic. I would want to know how aggressive he will let the therapist be while you are in the boot. If he says straight from the boot to riding…weeeeeell, from a load perspective, IMO, that would be tough.
Now I would advise talking with your physician about getting on no stirrups…Remember it is not the riding that is the problem, it is hitting the ground in the event of a what if that creates the problem…Risk vs. Reward
