Oh my goodness, I'm so sorry for your wife's accident. That sounds so painful, she must have a very high pain threshold for her to be able to get up and walk on her broken leg, and not go to the hospital for 3 hours. She must have been in agony. What a fluke accident to fall forward and be able to break your leg and knee in a seemingly small fall, I guess it must have been the way she fell or the angle that she fell on her leg that caused her to break it the way that she did. She will have a long recovery, and need physiotherapy before she will be able to fully use her leg again. What a terrible thing to happen and even more terrible with Christmas coming. My son broke his tibia in his ankle a few years back, it was a clean break, the tibia snapped. He was taking a short cut home, and hit a dead end with a fence, so he decided to hop the fence rather than go back and when he landed on the other side, he landed with all his weight on his ankle. He needed surgery with screws and it took a long time to heal. A year later, he slipped at work on some spilled hydraulic fluid and his ankle twisted or turned over, and he dislodged on of the screws, and the screw was sticking out under the skin. He required a second surgery to remove the hardware, and now he has constant aching in his ankle, and it always makes a clicking sound when he rotates his ankle, plus his ankle is much weaker now, and it turns over easily. I hope your wife has a speedy recovery, and her knee heals well. Sending love, hugs and prayers to her and your family.
