keep her LEASHED when she mets people. I'd have her leashed all the time at her age anyhow. step on the leash so she can not jump. praise her for not jumping.
OR don't let her met people until she is calmed down (still on a leash)
REMEMBER she is still a puppy.
Knee to the chest, is a hit or miss (no pun intended) correction. It is more important for you to not let the jump start. Give her an acceptable alternative. ie Sit. give no attention (greeting from people) until she is sitting. This is enforced by the leash.
