Your knee is one of the strongest joints in your body. It is also the largest and one of the most commonly injured. The knee is a modified hinge joint, similar to the elbow. The knee consists of bones, cartilage, tendons, and ligaments.
Knee injuries are prevalent and can be very debilitating. A knee injury may be acute – caused by a single action or sudden change in direction. Or, wear and tear can cause injuries to develop over time. High impact sports can lead to injury, but overuse can also cause sprains, strains and cartilage damage.
Swelling, instability, and popping are common signs of a serious knee injury. If your knee feels painful, unstable or inflamed, it is time to visit an orthopedic surgeon.
