Knee pain with road pedals

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Knee pain with road pedals

I currently use Look Keo pedals. Pedals were professional fitted with a proper bike fit. I can't seem to eliminate LEFT knee pain. Pain is anterior-medial ... almost right under knee cap. Went to 3 different bike shops for a "professional fit". My last bike fitter suggested I switched pedals to Shimano road pedals.

Any evidence that some road pedals aren't "knee friendly" to some as others? Just curious if this is a $$ well spent option to try.

p.s. - I've started seeing a PT ... apparently ... PT dx my knee as the infamous "petelo-femoral syndrome ... aka "runner's knee".

My bike shop recommended Speedplay to eliminate knee pain. Speedplay pedals have free float so your feet can move from side to side as you pedal. That said, some people need to have their feet locked so they can't move from side to side.

I can't see how switching to Shimano pedals would make any difference since they are designed to operate just like Look pedals.

Highly recommend Speedplay. However, they don't allow your feet to move "side-to-side," they allow your feet to rotate freely around the axis at the balls of your feet. I had bad knee problems with Shimano pedals before swithching to Speedplay (Zeros).

Another thing to consider is canting. I'm so bow-legged you could drive a small truck between my knees. I use canting shims between my shoes and my cleats and they seem to help as well.

Hope it works out for you!
cheers!

Yes, your explanation is much better. It was late when I wrote my explanation and my mind had shut down for the evening. Anyway, I am a big fan of Speedplay and will probably never ride with any other pedal unless there is a major break through in pedal technology.

Another happy Speedplay user here. My knees were giving me problems until I switched to Zeros.

Perhaps your legs are not quite the same length? Enough so that you may also want to look into trying a shorter/longer crank arm on one side...

It's been known to happen.

Pro fitters be damned (well not really) but don't take their word as the end all be all. Lower your saddle a few mm or raise it a few mm. You can also slide it forward or back.

I'm not sure if the Looks have float, but lots of pedals do. I run Time and like the float.

I used to get some knee pain on my road bike and I switched to a zero offset seatpost to get over the BB more, lowered the saddle a little and now I'm good.

Stop what you are doing. Bolt some platform pedals on you bike and ride in tennis shoes and see if your knee is restored to normal. Medial pain is likely either excessive pronation or you are restraining your toe position too far outboard. Purchase KEO max float cleats for 9.5 deg of rotation. Good Luck. Keep in mind that incorrect mechanics due to improper cleat orientation can injury your knee(s). You need to change your set up. The reason why platform pedals are better short terms is they reduce repetitive loading because your foot will naturally rotate to a more knee frendily position.

Shimano SPD pedals have generally about 6 degrees of float. Actually, the platform idea is a good one. You can even get the platform pedals with the little spikes, and use the marks they leave in your shoes as a key to aligning the cleats. That will help with toe-in/out issues.

As someone else commented, you may have "vertical out-of-plane" issues as well. Observe how your left knee moves while pedaling, does it go pretty much straight up and down, or does it move left & right as well? Is you lower leg vertical, or does it lean in or out? wedges uner the pedal cleats can help correct for either problem.

Finally, are you mashing with your left leg? It seems odd, but if your mechanics are otherwise OK, you may be using you left leg more heavily, whcih could lead to left knee pain. This is more likely if you are left-handed or a "forced right hander" (naturally left dominant, but taught to write and do other things right-handed).

The shimano platform is clone of the look platform. There will be little to no benefit in switching.

This sounds like your cleat is not properly placed on your shoe and/or your seat height is off. I would go back to one of the fitters you visited and get them to check out what's going on with your position. They should do a follow up for you as a service.
