with a lot of stitches it can be tricky to recreate. With 3 rows, I personally would not bother but start over. If the 1/4 of stitches lie next to one another, you will probably see uneven stitches after repairing (assuming we talk of a considerable number of stitches total).
But really: learn the fixing (for example in the videos up top) because sooner or later you will need it. When you walk you stumble sometimes. So fixing mistakes is a good skill to learn.
