Does anyone know why my knockout rose looks like this? 2 out of 3 look this way. Both were planted 10 yrs ago, and the 3rd was planted 1 year ago. The younger rose hasnt developed much, if any, of this. Should I remove them? If so, is it safe to plant more roses in same area? Any advice is appreciated. Thanks!

You could have rose rosette disease there. I have never experienced it, but that looks awfully red and thorny for a knockout. I hope someone with more experience will soon be along to advise you.

I had a branch appear on my Knockout that appeared to be Rose Rosette, I pruned out at the soil level. The rose is now fine 2 years later.

I thought it might be rose rosette after doing some research. I had a single branch like this come up last year and pruned it out. But almost every branch looks like this now. Thank you for the responses!
