First question

Question: I bought a Hanoverian broodmare 3months ago. She has great conformation and an awesome attitude. The last owner said she had a stifle injury and could not be ridden. But after 5 months of feeding her MSM, glucosamine and herbs she seemed as good as gold, galloping around her 5 acre paddock like a lunatic with her paddock mate ( A donkey). So I began to lightly hack her and do ground work on her. I did notice after she was mildly lame in the paddock (sound again within 8 hours) The question is is there anything I can do to fix her injury permanently?

Answer:

Anon, the first thing you need to do is find out exactly what injury she had, and when.
Go back to the old owner and see what info he/she has. If appropriate, see if you can get veterinary notes and opinions, including x-rays from the vet involved. You will need the okay from the old owner to get these,but as they were obviously open with respect to the injury in the first place, I would not expect this to be a major problem.
Then, if appropriate, present your vet with all the relevant info, to get his/her opinion about what could be done to help, and what her prognosis is. It all depends on what was damaged and the degree of the damage.
