PFPS : I think that you may be having pain around your knee cap which could be patellafemoral syndrome. This is when the knee cap doesn't track right. After your surgery sometimes even with pt your vmo of your quad isn't always working right. I would see a sports med/ortho or the doc who did the surgery (ortho) and they will examine and probabaly rx physical therapy.

Possibly: You may be experiencing the early signs of arthritic changes in your knee, which is a very common occurance after meniscal surgery. If it becomes to frequent or if you have persistent pain and swelling, you should see your doctor.
