I dont bend the knees but on the last 1-2 reps when I am struggling, it seems to bring in the erectors more because it is closer to a regular deadlift that way, but I dont bend them normally. The more you bend your knees the more its going to be leg movement as well, which again goes back to a regular dead. I have no knee problems right now so I dont believe for the moment anything adverse is happening to me because I dont bend them.
This is the only deadlift movement I do right now, and I do it on leg day.
