There are so many variables here (the nature of your injury, how much you've
recovered in terms of strength and flexibility, if you've developed other
weaknesses as a result of over-compensating for the original injury, whether
you're an over-pronater or have one leg slightly longer than the other, if
you're running on a cambered track or the side of slanted roads, the types
of shoes you're wearing, how many miles you run per week, how long you've
been running, etc) that any suggestions, including mine, have all the
validity of answers given on radio call-in doctor shows.  But here goes --
and my apologies up front if I'm telling you things you already know.

Different running shoes are designed for different things. Some provide
stability for over-pronators, some provide cushioning to ease impact, some
are lightweight for racing. From your description of having pain with shoes
on but none with them off, it might be that you are not an over-pronator but
are wearing shoes for an over-pronator that keep you from pronating at all.
If so, the shoe could be preventing your foot from moving in a natural,
non-injurious way, thus stressing your knee.  When you take the shoes off,
your feet move naturally and there's no stress.

If this is the case, you could try wearing a cushioned shoe that provides
little stability. This will allow your feet to move naturally while also
decreasing the possibility of impact-injuries over time.

As for your question about running barefoot, your better half is wrong on
this one. Not long ago, researchers at the Stanford Sports Medicine Clinic
conducted a study and found that most running shoes provide so much support
that they cause the foot muscles to weaken, making you susceptible to a
whole range of injuries up and down the leg.  Kenyan runners, for example,
train barefoot almost exclusively when they're young and rarely develop the
types of leg injuries that we do, despite their tremendous mileage.
Their recomendation was to wear shoes that give you only the support you
need -- not shoes that give you extra support. They also suggested doing a
certain amount of barefoot running. 

If barefoot running is working for you, you could just stick with it,
provided you're running on a forgiving surface like grass or dirt (pavement
is 30 times harder than dirt, and concrete 50 times harder) and are not
racking up too much milage. Stretching and strengthening exercises for your
leg would probably help out as well.
Switching to cycling may or may not be the answer. If the problem is in your
illiotibial band (pain on the outside of the knee, felt more when you're
running downhill), then cycling will probably hurt as well.  My advice is to
go to a specialty running shoe store with your old shoes, have them analyze
your gait and the wear on your old shoes and hopefully they'll come up with
a better pair for you. And go barefoot when you feel like it.
