Knee pain is quite common and affects people of all ages. This could be a result of an injury such as a ruptured ligament or medical conditions including arthritis and infections which can also cause knee pain. The location of the knee pain can vary depending on which structure is involved. For instance, with infection, the whole knee might be swollen and painful, while a torn meniscus or a fracture of a bone gives symptoms only in one specific location.
The signs and symptoms that sometimes accompany knee pain include:
• Weakness or instability
• Crunching or popping noises
• Inability to straighten the knee
• Swelling and stiffness
• Redness and warmth to touch
There are several factors that can increase one's risk of having knee problems, including:
• Being overweight or obese can increase stress on the knee joints
• Lack of strength and flexibility can cause knee injuries
• Certain sports where there is greater stress on the knees such as basketball jumps
• Having a previous injury makes it more likely that one will injure his knee again
