Knee injuries can strike because of added stress on your knees, as well as normal wear and tear, which means that the older you get, the more likely you are to injure a knee. At the same time, you can develop a torn tendon or ligament from twisting your leg while involved in any activity from aerobic dance to a pick-up basketball game. Knee pain usually occurs when you damage the cartilage or the knee joint. Signs that you’ve injured your knee include: - A swollen knee that’s painful - Inability to bend or fully straighten your knee - Popping or cracking sounds whenever you move your knee - A knee that gives way suddenly - Loss of muscle strength and flexibility - Redness and warmth to the touch You can injure your knee in many ways, and each may have a different effect. That’s because your knee joint is a complex structure of bones, cartilage, muscles, tendons, ligaments and other soft tissues. While a swollen knee is the first indication of an injury, how it plays out depends on the actual injury.
