What is the affiliation between KM and crossfit?

I am trying to understand the affiliation between some KM schools and crossfit. CF is hard core conditioning, a friend did it, but I have some previous injuries and when I have done P90X I almost couldn't walk because of my knee joint, one of the injured areas. From my understand CF and P90X both share high intensity training. Is this a requirement for all KM schools to do intense cardio. My cardio is good, but I am not looking to jack my knee joint on a regular basis or re-injure my lower back.

just do km you dont have to do cf ive tried to do cf but im too uncoordinated to do most the Olympic lifts it would take too long to get proficient at them so i figured my time would be better spent somewhere else but km likes cf for its short extreme bursts of workouts like in a fight

The only link I really see between the two is that KM warm ups are pretty cardio intensive. We do focus mitts/Thai pads combinations and CF would be a good way to supplement your training cardio wise. I would take CF in addition to KM but I do not have the time and the workout is not my priority... but my school does offer CF classes.
