Persistent posterior knee curvilinear calcification and anterior knee preps teller sub centimeter opacities are noted.. what does this mean?

Hard to tell without: seeing your x-ray, but the body makes calcifications when it recovers from inflammation, or when a bone is broken. In older individuals, posterior knee calcifications are often hardened arteries, but at 21 that would be very unlikely. If you have your x-ray on a CD, I can explain it at HealthTap Concierge healthtap.com/saurbornmd.
