Replying to Should I be in the search of new bindings?

So last month I twisted my knee real bad and my px-12 bindings didnt release.. Im 5'11", and 165 pounds. DIN was set to 6.5 . Long story short, Im getting an MRI this week because my knee still doesnt feel any better and Ive missed a ton of the 2.5 month ski season in Pennsylvania. From what I understand, the PX-12's have a high elastic travel, so why did this happen?.... Should I be looking for a new binding? Would pivots be beneficial? Help please I dont want to go through this again..
