I had a pretty bad leg injury (on top of the TPF I also had a knee dislocation, 3 breaks in the fibula, and a long vertical split in the tibia. I was NWB and in a wheelchair for 15 weeks.
2.5 weeks ago I was given the OK to get out of the wheelchair and start weight bearing. Bad news: It hurt and still does. Good news: the pain is not anything near the pain I had experienced with the initial injury and those first few weeks post surgery.
I started with crutches and within 8 days I moved onto a cane. What I have gathered from my doctor and physical therapists there is a reason that I will be back on a bike and hiking by the spring of 2015…provided I continue working on my strengthen exercises.
I would imagine the same holds true for you. Like me, it sounds like you were active and in good shape to begin with. Just continue to work on your ROM and strength.
