The human body is a remarkable " machine"
It's able to compensate for muscle weakness and some injuries.
Before your surgery, you had a bad knee that lacked stability. Your body responds by tightening your hamstrings to help limit your range of motion, in effect helping stabilize your weak knee.
The Yoga by stretching out your hamstrings didn't cause instability, it just exposed the weakness.
If your knee is fixed, Yoga can only help if done correctly. Their are a myriad of home yoga tapes that target specific problem areas. I know theres a number for lower back issues.
Nothing the matter with home exercise tapes, but I would recommend a few lessons with a certified yoga instructor to make sure your doing things properly.
Proper form is the key to any exercise you do.
Sometimes the home DVDS are lax in emphasizing that or the camera angles/edit doesn't give you a proper view of what you should look like in a given pose.
Doing your workout with a couple of mirrors for front and side views is a big plus for making sure your body is aligned properly

[quote]Yoga is awesome.  The best exercise around. [quote]

Awesome, yes it is.
Best Exercise, that depends on what your looking for in a workout program?

Flexibility/ muscle tone/ increased lung capacity/ overall body health, yes to them all.

However if your into a sport that requires long term muscle endurance like cycling/rowing/ cross country asking etc, it will help on your off training days but it won't get you in shape for those activities.
The best exercise for you sport(s) is actually doing that activity. If you can't do the activity you want a workout or exercise machine that can mimic the muscles used and body movements as closely as possible.

The best workout regime is one that combines the Big 3, Cardio/ Resistance work/Flexibility.
You can emphasis one or more for the specific needs of your given activity, but there all important and far to often one or more are overlooked.

Even the best exercise machines have there limitations.
Rowing is a great exercise but it does have a drawback?
Like cycling, rowing doesn't put a load on the skeletal system.
Not an issue until you swing that heavy portage pack/canoe/backpack and head off down the trail.
Cross training is the key. Find cardio/resistance workouts that mimic as close to possible the muscles/movements( if possible) of your chosen activities and you'll be on your way.

WOW.........how cool is that! Who would of thunk it? Thanks PG.
