You may just have to skip max jerks for the time being and push it in other ways. If you're doing max triples, for example, even if you miss the last rep, the weight may be one that you can still bring back down to your shoulders.
You can also do a lot of other exercises for the jerk during this time. For strength, jerk dip squats, split squats or split walks and push press. You can also do variations like pause jerks (pause in the bottom of the dip for 2-3 sec), jerks behind the neck, power jerks, etc. And complexes like push press + jerk, multiple dip squats + jerk, etc. In that way you can still push toward maximal effort, but with weights you won't need to drop in the case of a failed rep.
