Flexibility update: I'm able to touch the ground now with my knuckles and legs straight. Prior to surgery, I was able to touch the ground with my wrists with legs straight. This means that if you subtract the 3" height gain, I am back to my pre-surgery flexibility when it comes to bending down and touching my toes.
Things I still can't do: Crouching. Squatting. Walking down stairs without holding onto a railing. Walking up stairs by alternating my legs without feeling tightness in my muscles. Walking without looking like a penguin. Walking more than two blocks (5 minutes) without getting tired. Spreading my two legs apart more then 60 degrees. This is probably my worst flexibility. The tendons in my inner thighs are very very hard to stretch. Prior to surgery, I was able to spread them more than 130 degrees apart. If I bend my knees, I can spread them 90 degrees apart. But straight out, only 60 degrees. This hinders my athletic ability the most besides the stamina. I assume that I can regain my stamina, but this flexibility seems like it's lost forever.
