Thank you for the question. It sounds like you are already seeing someone about your knee symptoms and they have given you some reasonable options. In some respects it depends on your symptoms.
If you are having recurrent instability and dislocations, then, depending on the frequency and it’s impacting your daily activities, then a surgical treatment maybe appropriate. They might do a lateral release or, if you have a shallow femoral trochlea, your surgeon might try a patella tendon transfer.
Either way, surgical treatment is invasive, you’ll have to deal with the post operative phase and need lots of rehab afterwards - trust me, I’m speaking from personal experience.
If on the other hand your symptoms are not so troublesome and rather than dislocations you experience subluxation, then rehab might be best. Often this will involve loosening off the ITB and strengthening your quads. You could see a sports/msk physician or a physiotherapist to look into this.
I would encourage you to discuss further with your current doctor as well.
