If you have a row of twisted stitches, you can correct that row by knitting through the back loop, and start correctly on the next row.
However, if you've twisted more than just the row you've corrected, those stitches will look different if you're working in stockinette. If you're working garter stitch--knit every row-- then I don't think the twisted stitches will show.
If you've worked the entire thing in twisted stitches in stockinette, you could continue working them twisted for the rest of the project and call it a design. A pain-in-the-butt design to work, maybe, but it will be consistent.
