<human>: Can you succinctly summarize the text in 1-3 sentences?

So, a few years ago I got big into running. Lost a bunch of weight, almost passed my wife as she was in the midst of gaining weight during pregnancy (guys, don't do this!).

But I was running for about a year and a half on the same old shoes. Entered a 10 miler race and hurt myself. Realized afterwards that my shoes were kind of shot and I needed new ones. Beginners error. Got new shoes, and started up again.

But every time I got around 3k, my knee would just seize up. Seemed to be the tendon under the knee cap. Confirmed with a physio. Did "electro shock" treatment to strengthen the tendon. Was given a number of stretches and exercises to do for the surrounding muscles. Mostly did them. But I still would have problems when I ran longer than 3k. 

Since then (this was about 2 years ago), I had stopped running really. Got lazy for the most part. But recently, I'm getting back into it again. But the knee is still sore afterwards and during. I'm keeping my runs to under 3k now. I've had a couple runs where I've pushed it past 3k. But then my knee is sore the next day. I have no problem with the distance, its just the knee. So, I'm getting a little bored not being able to push myself.

If you've read this far, thank you. My main question is with the right combination of stretching, exercises and slowly increasing my distance, will I be able to increase my distance?

Or should I just go for either the band around the knee to hold the tendon in place (Pro-tek thing) or should I try changing the way I run (pick up those Vibram shoes)?

Any advice would help
<bot>: Developed runner's knee a few years ago and it won't seem to go away with stretching and rest. Looking for other options.
