Adaptive seats because of Total Knee Replacement After TKR (total knee replacement) have a difficult time in foot placement on pedal, my right foot falls in middle due to range of motion? Any ideas or suggestions?

I thought if I found a seat that sat back, it would allow for right foot to hit at ball!
There’s a company called Rans

that makes bikes that they call crank forward.  You might say it’s halfway between a recumbent and a conventional bike. 

They cost more than I would be inclined to pay, but your seat will be back.
