Becky.....it is possible, if your knee was bad enough, that the sudden straightening of it with the TKR resulted in a shift of your body's alignment. This can cause all sorts of aches and pains as your body readjusts itself. Time will take care of this.
It's also possible to get a flare up of plantar fasciitis after a TKR. Be sure you are doing stretches to keep everything loose in your leg. An excellent one is to stand with both feet on the edge of a step or raised platform. Balance on the balls of your feet with your heels extending beyond the step. Hold on to the hand rail and slowly lower yourself a few inches so that your heels are below the step level. You should feel a pull in your calves and that's the stretch. Hold it for a count of 10 and then slowly come back up. Do about 10 of these stretches a couple of times a day and see if that helps your discomfort.
