Prayers going up for all those in need. My FIL had knee replacement several years ago. It took a long time to heal. He had his other knee done a fw years ago and he was much better recovering the last time. He was a wooden boat builder and spent many hours on his knees planking and plugging the hulls. In fact his first knee now needs to be replaced, because he has worn it out. He is 82 and said that he was not having it done again. He had open heart surgery 3yrs ago to replace a valve. That also took him a long recovery time mostly due to his age.
