Sprain of the stifle joint proper may come from slipping and falling, or it may come from pulling in deep, sticky mud.

Symptoms. - The horse stands with the leg flexed and the stifle dropping forward and downward. There will be lameness in both walking and trotting, and the leg moves stiff and stilty, as if too long for its mate.

Treatment. - Reduce the inflammation with either hot or cold water, and then apply the ammoniacal liniment three times a day to both inside and outside of the stifle joint. The horse must have complete rest from work until entirely recovered.
