I know this is years after the fact, but I was searching for similar issues and found yours. Wondering how your situation turned out.
I broke my T12, fused from T11-L1, and suffered a Schatzker level VI tibial plateau fracture. Haven't jumped since August 2010. I have two plates, 10+ screws, and wire in the leg. Also a bit knock-kneed now.
I have a unique healing story, though, because even though I suffered the worst TPF possible, I have almost full extension and 130 degrees of flexion. I shattered the leg in May 2011, and I still can't run or hop.
