I took a hard fall from 4 ft. I broke my left foot in 4 places and my right leg I broke my tibea plateau. The first ortho wrapped my broken foot in a ace bandage and said only 1 fracture on the toe and said my knee was bruised. I was unable to bear weight on either leg so I got a 2nd opinion. I was sent to get a cat scan and that s when I learned I had 4 breaks on right foot and left leg tibia plateau broke. My injury occurred 5 weeks ago, I have a leg brace 0-90 but wen I try to stand on my leg my knee starts shaking and it pops and causes more pain and I lose my balance and fall. Should I get a mri to see if there is more damage than just the tibia plateau?
