Knee pain is a common problem that can originate in any of the bony structures the make up the knee joint, the kneecap, or the cartilage and ligaments of the knee. Knee pain can be aggravated by physical activity, as well as being overweight, affected by the surrounding muscles and their movements, and be triggered by other problems (such as a foot injury). Knee pain can affect people of all ages, and home remedies can be helpful unless it becomes severe.
The main function of the knee joint is to bend and straighten for moving the body. The knee is more than a hinge…it also twists and rotates. In order to perform these actions and to support the entire body, the knee relies on a number of structures, including bones, ligaments, tendons, and cartilage.
The location and severity of knee pain may vary, depending on the cause of the problem. Signs and symptoms that sometimes accompany knee pain include:
• Swelling and stiffness
• Redness and warmth to the touch
• Weakness or instability
• Popping or crunching noises
• Inability to fully straighten the knee
