To regular practice, yes.
For seminars or ceremonies, no.
Also, I tend to wear out the hem of my hakama before anything else (helps me remember to keep my knees bent if I am brushing/dragging the hem on the mat), so while I may not have patches on the knees, I usually have a band around the bottom where the hem has been replaced. I do have one very faded hakama with both knees patched, the hem resewn, and the panels where the himo's tie around patched due to wearing through; generally gets some smiles.
