This is a big 'it depends'. If the other grout is good, just clean out
a bit beyond the damaged area and give it a shot. I did this on a
tub/shower several years ago and it worked fine. I was also able to
feather in the replacement grout a bit by rubbing a wet finger of the
new grout over the old grout.
Remember that transitions from wall to floor/tub/other walls should be
caulked. My new house has a good amount of floor damage because the
person that renovated the bath and tile shower for the previous owner
didn't believe in caulk.
If you have a bunch of grout to remove, the HF oscillating cutter with a
grout blade works well. Just plan for the dust and noise - hearing
protection, mask, glasses, and plastic to contain the dust.
