Hello,Customer

 

Firstly, thanks for providing a needed home for this rescue horse. The need for good homes is increasing daily, and we certainly need more kind hearted people such as youself. Thank you.

 

In the case of your horse's swelling knee, I need to ask you a few questions in order to help.

 

1): Do you know how long the swelling has been present, and do you know what caused the problem?

 

2): On a scale of 1-5, with 5 being non-weight bearing, how lame would you judge the horse to be?

 

3): Just to clarify the location, as terms can sometimes be used interchangebly, is the swelling on the front leg?

 

4): Can the horse bend it's knee (or can you) fully?

 

5): What breed and sex is the horse?

 

6): Have you attempted any treatment for the swelling, and if so, with what, and was there any success?

 

Thanks, XXXXX XXXXX'm looking forward to your reply.

The large lump is on the front of her knee..she can still bend it fully...it is not hot...feels like a firm mass...its a quarterhorse mare..she was walking fine with no limp ..but it is getting larger and she has now started to limp...unfortunately at the moment where i am there is no vets that do house calls ....i have a vet that will start up in april ..as i live far out in the mtns..she had come from a cattle farm..where she wasnt being taken care of properly...she is on the thin side ...seems hard to get any weight on her at all..she eats fine ...her real age is really unknown ...i have given her some bute to help but i just started her on that..i didnt know if i should wrap it up or not....

HiCustomer and thanks for getting back to me.

 

Based on your description of what is occurring, there are several possibilities that could explain your mare's condition. My first thought was a condition known as a carpal hygroma, which is basically a buildup of joint fluid normally on the front of the knee (carpus). There is normally no lameness associated with this condition and it usually has no long term negative effects. I have an older quarterhorse mare that has had hygromas on both of her knees for years with no ill effects. However as it seems as if you are beginning to see some signs of lameness there could be other possibilities as well. There is a good possibility that the swelling has been caused by some sort of trauma to her knee, resulting in inflammation within the carpal joint capsule, which in turn results in a buildup of joint fluid in the capsule itself, along with sensitivity. Another possibility would be the existence of a fracture within the joint, which of course can only be diagnosed with an x-ray. Unfortunately in your mare's case, without some additional diagnostics (x-ray, ultrasound and/or vet exam) it is extremely difficult to say what the exact problem is. What I would recommend is a daily dose of cold water therapy, which consists of letting cold water from a garden hose run on the swelling for at least 10-15 minutes. Following that, application of DMSO directly onto the swelling may be beneficial as well. You should be able to obtain DMSO at either your local feed/supply or drug store. Be sure to wear gloves when applying. As far as the bute, as this is a prescription drug and I have no way of examining your horse, I can not legally give you a dosing regimen as there is no patient/doctor relationship. I can say, however, that if you are to administer it, not to exceed one gram twice daily. If you can get ahold of the doctor who is opening a clinic in the near future, she or he may be able to give you specifics over the phone. Again, without being able to examine the swelling, I can't recommend or discourage a wrap at this point. If there is active swelling, inflammation of the possibility of infection, a wrap can be counterproductive. Your best bet is to try and keep her confined to a stall or small paddock to limit the amount of activity on the knee.

 

As far as her weight problem, be sure that she is up to date on her deworming, and try to have her teeth examined as soon as you are able, as these two factors are the major causes of weight loss in the horse.

 

I hope I've been of some help, and please let me know if you have any further questions.

 

Thank you, XXXXX XXXXX of luck!
