suspensory ligament injury

About 2 years ago, my 7 year old Canadian had a suspensory ligament injury because she got caught in a wire fence. She recovered, but can it recur? For the past week or so, she has been limping on the same leg that she had her injury on before. I can feel any heat and there is no swelling.

Also, after an injury like that, is it risky to jump her in the future?

Thank-you :)
