Knees are one of the hardest working joints of the
legs. They support nearly the whole weight
of the human body. Thus they are
vulnerable to both acute injury and the development of osteoarthritis. The knees are the largest joint in the human
body and are very complicated.
Knee pain is commonly caused by trauma, joint misalignment,
and degeneration as well as by conditions like arthritis.
The most common knee disorder is generally known as
patellofemoral syndrome which is characterize by pain or discomfort seemingly
originating from the contact of the posterior (front) surface of the patella
(back of the kneecap) with the thigh bone.
The second major class of knee disorder involves a ligament
or tendon tear, slippage, or dislocation that impairs the structural ability of
the knee to balance the leg.
Other cause of pain may be from excessive on, and wear of,
the knees, in combination with such things as muscle weakness and being
overweight.
