The knee is the most commonly injured joint in all age groups. It is especially susceptible to damage during athletic activities and exercise. Many knee injuries can be treated conservatively with rest, ice, mobilization, and physical therapy. Knee pain may be the result of an injury, such as a ruptured ligament or torn cartilage. However, certain medical conditions, including arthritis, gout and infection, may be at the root of your knee pain. Some common causes of knee pain and injuries include:
A blow to the knee, either from contact during sports, a fall or a car accident
Repeated stress or overuse, which may occur from playing sports or any other activity that requires frequent repetition.
Sudden turning, pivoting, stopping, cutting from side to side, which happens frequently during certain sports.
Awkward landings from a fall or from jumping during sports, such as basketball.
Rapidly growing bones, which are especially prone to injury during sports.
