knee

[nē]

Etymology: AS, cneow

a joint complex that connects the thigh with the leg. It consists of three condyloid joints, 12 ligaments, 13 bursae, and the patella. The motion of this joint is not a simple gliding motion because the articular surfaces of the bones involved are not mutually adapted to each other. Various orthopedic conditions such as arthritis commonly affect the knee, especially in elderly individuals. The knee is relatively unprotected by surrounding muscles and is often injured by blows, sudden stops, and turns, especially those associated with sports. Ligament tears of the knee joint are extremely common in athletes and produce a variety of signs and symptoms, such as effusion, varying degrees of edema, differences in the shape of the knee joint, tenderness on palpation, crepitation, instability of the knee joint, and possible ecchymosis. Torn menisci are very common sports injuries and can cause severe pain, limping, edema, and greatly reduced motion.

knee [ne]

the area around the knee joint, a hinge joint that is one of the largest joints of the body, sustaining great pressure. The knee is formed by the proximal portion of the tibia, the distal end of the femur, and the patella, or kneecap. The bones are joined by ligaments, and the patella is secured to the adjacent bones by powerful tendons. The fibula is attached at the side of the knee to the tibia. Two crescent-shaped pads of cartilage, one medial and one lateral, called menisci, lying on top of the tibia cushion it from the femur and form the gliding surfaces of the joint in motion. Further cushioning is supplied by bursae, which are located around the main joint, between it and the patella and on the outside of the patella. A capsule of ligaments binds the whole assembly together. The capsule is lined with synovial membrane, which secretes a lubricating synovial fluid that makes possible a smooth, gliding motion. Traumatic disorders of the knee are common and include dislocation, sprain, and fracture.

knee jerk (knee reflex) a kick reflex produced by sharply tapping the patellar ligament. To test this reflex, the lower part of the leg is allowed to hang relaxed (such as by crossing the legs at the knees) and the examiner taps the ligament below the patella with a small rubber hammer. The normal reaction is contraction of the quadriceps muscle, causing involuntary extension of the lower leg. This is a stretch reflex; striking the patellar ligament stretches the quadriceps muscle at the front of the thigh and causes it to contract. Two nerves are involved; one receives the stimulus and transmits the impulse to the spinal cord, and the other, a motor nerve, receives the impulse and relays it to the quadriceps muscle. Inadequate response to the knee jerk test may mean that the reflex mechanism involved is in some way impaired. In some people with normal reflexes the jerk of the knee is so light as to be nearly imperceptible, and the examiner must make other tests to check the reflex mechanism. Called also patellar or quadriceps reflex.

Q. Can knee pain at childhood be connected to osteoarthritis? My mother is suffering from osteoarthritis (OA). She is 72 years old and the OA is a major problem in her life. My son is 10 years old. He has a relapsing knee pain. His pain occurs mostly at day time but can wake him from sleep. The pain is in both legs. Is my son in a risk group for OA?

A. Osteoarthritis is a disease that is most commonly caused by weight gain. The problem is that weigh gain has an important genetic factor. So, it doesn't matter if your son has knee pain right now, he is in a risk group for OA. If your mom is fat, she can start a program to lower her fat rate. I used this program for me. In the beginning it was too hard so cut her some slack!

It sure sounds like something i suffered from. Go see your GP and don't worry. if it is what i had he will probably tell you that
you can take any NSAID you want, and if you will give yourself a break from competitive sport for a month or so you will be just like new :)
