By the time Blake was ready to really begin, they'd finished X-Rays and wheeled in the Flash, now slightly less impressive in a hospital gown and scrubs, and he greeted the interruptions with relief. It wouldn't really distract the kid from what they were about to do, but maybe it would help a little. At the very least it would let him focus on making each movement fast and perfect.
Except for the question that made the kid's voice waver in spite of an attempt to sound brave. It could have been the pain, but he really did need to answer the worry. "I've seen double amputees run marathons, and that's not what we're doing here," he said as he picked up the first piece of the new joint. "You will be fine."
Thousands of knees were replaced every day, but none quite like this; it wasn't a long operation, usually, but Blake was sure he set a speed record, waiting only long enough for the bonding to settle before moving onto the next step. Especially since moving on usually involved curbing flesh and tendon back so he could get where he needed to.
And then it was done, and he wanted to suck in a hard breath and laugh. He wasn't sure he actually needed to suture the knee at the rate it was healing, but he did so on reflex, and lifted his hands to strip off the bloody gloves. "I'm done here - let's get him casted. Then show me the X-rays and get me something to break bones." Not the usual or the prettiest surgery, but it was done and the kid was going to be just fine.
