Which would you rather lose?

(For those interested, I tried ice skating, which I already knew that I sucked at, and accidentally put all of my body weight on my left knee at a very, very bad angle. Long story short, my knee gave out, popped and dislocated itself somehow bending outwards so that my leg made about a 150-160 degree angle instead of a straight 180 degree line, I went down and biffed it on the ice, but when my knee hit, it forced the joint back into place quite abruptly and rather painfully too I might add. It took the better part of a day and numerous ice packs before I was able to put any weight on it without passing out from the excruciating pain and agony. Now years later, I look back and cuss myself out for not going in to have it properly looked at and professionally taken care of, due to the way it healed. I can still walk on it fine, but my right leg tires and gets sore faster and easier than my right, I have a slight and almost unnoticeable limp, thought only because I actively try to conceal and compensate for it, it has slower response and reaction time and it can be harder to move at times. So, yes I would definitely give up my legs before my hands and arms. But in another decade or two, science will have found a way to clone entire limbs in vats and successfully hook up all the little nerves, muscles and bones so as to completely replace lost limbs, I'm almost certain of it.
