Knee pain almost 1 year after arthroscopy

So i tore my meniscus in the summer of 2015 and had surgery to repair it June 2015. (I was 16 at the time). fast forward to march 2016, i ended up tearing my meniscus a second time and had another surgery to repair it. i went through all the rehab steps and haven't experienced many problems with my leg except for the general weakness and fatigue if i endure activities for too long. recently, about a week and a half ago, my knee has started hurting towards the side/back (lateral side, where i had my surgery). it's nothing serious, it's definitely not serious pain, but just the fact that it's been hurting after not doing anything strenuous is worrying me. should i see my doctor or should i wait it out and see if it gets better?

Dear Jenna:

How was it repaired? suturing only?

Did your doctor place an implant called Actifit?

Best,

he repaired it using 4 sutures
