Knee pain is a common problem that can originate in any of the bony structures compromising the knee joint (femur, tibia, fibula), the kneecap (patella), or the ligaments and cartilage (meniscus) of the knee. Knee pain can affect people of all ages.
The location of the knee pain can vary depending on which structure is involved. With infection, the whole knee might be swollen and painful, while a torn meniscus or fracture of a bone gives symptoms only in one specific location.
The severity of the pain can vary, from a minor ache to a severe and disabling pain.
Some of the other findings that accompany knee pain are
- difficulty walking due to instability of the knee
- limping due to discomfort
- locking of the knee (unable to bend the knee)
- redness and swelling
