Within the last decade, the amount of ACL tears in adolescents has increased by 400%. Since this injury cannot heal without surgery, you need to visit a doctor if your knee feels unstable, because it will require surgery. If you choose to keep exercising with the injury, you can cause even more damage and be out of your sport for longer, or possibly be out of it forever.
One way to prevent ACL tears is to strengthen the muscles around it. A simple preventative exercise you can do every day is the box jump. Jump up and down on and off a stair about 10 times as quickly as you can. This will build the muscle around your knee so there’s extra support.
You only get one body and not every part of it can heal on its own! So take preventative measures to take good care of it!
