I have had chondromalatia patella for seven years, I have done physical therapy, but it is not better, what should I do, should I have surgery?

You might need it. If you have had the problem for seven years and you have not improved with therapy or other conservative treatments, you may need to consider arthroscopic surgery. While surgery for this problem is not the first line of treatment, an arthroscopic surgery can be helpful to improve the situation.
