cardio exercise with a meniscus injury

Bx Belly Dancer,

I understand you want to keep on doing cardio.

Please consult with your ortho on the exercises. Meniscus, if it is of the healable type, can be reinjured.

I am bummed.. Im getting married in August and wanted to lose some weight.. i started taking step and kickboxing classes and it is there that I tore my meniscus.. i really dont want to stop working out if I dont have to.. What are the best cardio exercise machines or classes that I can have my work out and still heal?
