Taking a fall is the last thing on your mind as you head down the stairs to the snack room for your morning break. However, the overhead light at the curve in the stairway has gone out.
You misjudge the step and stumble and fall, injuring your knee. At first, you only feel some pain and tenderness. But by nightfall, your knee is swollen and causing you considerable discomfort. You decide it’s best to see a doctor.
The main cause of knee problems
Some knee problems result from underlying health conditions, such as osteoporosis, but sudden injuries are the most common cause of knee issues. When you fall, your knee could suffer a direct blow if you hit the ground or a hard object. Many knee injuries also result from an abnormal twisting motion, during a trip or a falling accident, or while performing routine tasks in the course of work.
