Depends how serious the injury was, how it was caused, how long ago it occured, how well it had healed and whether or not there were any complications as a result of it!
But probably no to be honest! It would depend what you wanted the horse for and for me they would have to prove it was only a minor injury and the horse would have to pass a vetting.
Depends what you wanted it for.
Laid back hacking and a few local shows then yes.
Anything more no - Suspensory injuries are a b#tch, and very likely to reoccur.
you also need to consider that your insurance company (should you insure said horse ) will exclude that leg from your policy, so if it were to reoccur you would be responsible for the total vet bill.
