My son hurt his knee at the the beginning of the second game during football this year. He tore his ACL completely in two, tore his meniscus in four places, and strained his MCL. He missed the rest of the football season and is out for all of basketball. He's out 6-9 months and has suffered a lot. The doctor expects a full recovery but he has a long hard road ahead. The local orthopedic doctor wouldn't touch it because of the severity of it. He was sent to the former doctor for the Tennessee Titans. I've seen injuries to others but when it hits home it causes you to have a lot more empathy for others.
