Different bike fit for total knee replacement?

[Trek420]

Awsmile, here in Seattle there are several bike fitters who are PTs. I would think a PT bike fitter could be very helpful to you.

Yeah, we do have several with that skill set in the PNW. But she's in Western PA? Yes, I would look for a bike fitter that's also a PT.

I don't have much pain in that knee when I ride, but discomfort behind the knee which is directly proportional to how hard I'm cranking. And in Western PA, you don't ride more than a quarter mile without a good-sized hill to climb. Any thoughts? Thanks!

I agree you may be advised to crank less hard. Not climb less but gear down to more of a sit and spin. I agree with Murien to have your PT look at the gearing.
