management for a locking stifle is lots of room to move around in pasture and lots of walking under saddle. Just keep her relatively fit (not sure if possible with ringbone), and she shouldn't have much of a problem with it.


That's actually the recommended treatment for most cases of ringbone as well. So long as you keep them moving around they tend to remain servicably sound and functional for very light work.
