Know Your Knee
The knee joint is one of the most complex joints in the body. It consists of bones, ligaments, and muscles. The knee is made up of the femur (thigh bone), the tibia (shin bone), and patella (kneecap). The meniscus, a soft cartilage between the femur and tibia, serves to cushion the knee and helps it absorb shock during motion.
The stability and strength of the knee joint is maintained by four ligaments: the medial collateral ligament, lateral collateral ligament, anterior cruciate ligament, and posterior cruciate ligament.
When any of these structures are injured you may have knee pain and difficulty in walking and performing activities. You may hear a popping or snapping sensation at the time of the injury or you may feel like your knee is giving way. You may also have swelling, limping, and inability to move the knee. If care is not taken during the initial phases of injury it may lead to joint damage predisposing you to osteoarthritis.
