Hi All, I've signed up just to post this.
I suffered 6 months of knee agony and really sympathise. I hope this helps.

During my injured period (walking up and down stairs were a problem) I believed at first it was down to:
[ulist]
[li]Having young kids (on my knees most of time)[/li]
[li]Rapidly ramping up my riding (to 18 miles x 2 per day x 4 per week)[/li]
[li]A couple of knocks when falling off (off road).[/li]
[/ulist]
However, had consultation and x-rays. Docs said there was nothing wrong with my knees, I think they thought I was wasting their time, so I quickly gave up on professional opinion!

I have over the last few months worked out what's best for me:
[ulist]
[li]set seat height so that my leg is straight with heel of shoe on centre of pedal at bottom of stroke. Then raise seat an extra 5mm![/li]
[li]raise bars if you can. If you're not very flexible, this can help stop your tight tendons pulling your muscles/bones out of line if you've got a high saddle (see below *).[/li]
[li]set seat horizontal.[/li]
[li]set cleats on shoes so that weighting the shoes doesn't cause my foot to rock either inwards or outwards, for me that's slightly inboard of the centre line of my foot. I guess this depends on the width of your hips, and the type of pedals/shoes/cleats you have.[/li]
[li]set angle of cleats so that my heels can almost touch the chainstays (5mm away). My feet are slightly overpronating and stick out slightly. I believe this stops my knee coming too close to the crossbar and helps alleviate pain caused by misalignment of my kneecap on the downstroke.[/li]
[li]with cranks level and cleats clipped in, the front of my kneecap is about 10mm in front of a vertical line passing through the centre of the pedal spindle.[/li]
[li]don't crank too hard away from lights and junctions (no matter how tempting it may be!).[/li]
[li]and don't ride too far too soon if you insist on sprinting![/li]
[/ulist]

• I had a colleague who was told the pains down the outsides of his lower legs when he walked (which he thought were to do with bow-leggedness) were all to do with his posture over many years. He had a course of physio where they taught him how to walk better for his condition. He started to feel improvements in weeks. His leg problems were to do with tendons in his back!
  
  

Good luck.

BTW, all this was on a geared bike. I ain't got a proper bike yet!
