Can a knee replacement cause plantar fascitis?

Possible: Anything that causes your feet to be repositioned can cause pain.

Rarely: It is possible you could get plantar fasciitis if you are placing more stress on the foot. For instance, if you had knee surgery on the right and you increased the amount of standing on the left foot, you could inflame the plantar fascia. Also, if you are not walking normally in general due to the knee replacement you could overstress the plantar fascia. If you suspect this, talk to podiatrist.
