Limp? It's totally gone, unless you ask my wife, or the guys at work, or my therapist. What do they know, I don't feel any limp! I haven't tried running, it does hurt sometimes, but I hammer on my bike every day and that feels great. At the gym, I'm less than half-strength on right leg extension compared to left leg. I think my body mass is back to where it was, I'm still not up to 100 pushups every morning, but I'm gaining on it, slowly. Sucks getting old! Kinda fun when I catch up to a roadie on my mt bike, then he sees my grey beard, heh! I needed to stop running anyway, so I don't miss that after 25 years of running, but I am limited in peak strength on my right leg, so not much hill climbing. There are some steep, paved hills near my house, I may start hitting them on my commute home just to see what I can do.
I had the hollow pin removed from my leg a few months ago, that was possibly causing pain because it didn't flex with my bone, possibly bruising the inside of the bone.
No airline flying yet. The most dreaded challenge in airline sim training is the engine failures. The plane yaws to the side, which on a swept-wing plane puts a lot more wing into the wind on the upwind side, and a lot less wing on the downwind side. That means a lot more lift on the upwind side, which causes the plane to roll over, fairly quickly at low speeds/high thrust (on takeoff). The pilot flying has to put in a lot of rudder to stop the yaw, that means pushing one rudder pedal with a lot of force and grace. It's sort of like standing in a one-legged squat. The force has to be adjusted smoothly as the plane accellerates (rudder & engine become more effective) and the throttles are adjusted, to keep the plane going straight. In the military I flew with a lot of serious injuries, took aspirin 'till my ears rang, did my job. We don't do that in the airlines, no-one would suggest it.
I'm happily working as an engineer/project manager/account manager, designing and building automated industrial machinery. I love it, and I love seeing my family every day, going to church, going to my kid's games, real life.
