Knee Osteoarthritis Part 2 Symptoms Evaluation
(light rock music intro) Welcome back to The Art of Medicine. The diagnosis of osteoarthritis depends on carefulanalysis of your condition. Let's take a look at the common symptoms and how we evaluate your pain. Symptoms for osteoarthritis are three. Pain, swelling and stiffness.
They can all either bepresent at the same time or you can see each one individually in different degrees. The pain can either bebecause of particles flaking off and irritatingthe lining of the joint or increased pressure within the bone. Similarly, the stiffness can be because of fluid inside thejoint or it can just be
because of increased pressure in the bone because of not havingas much cushion there. Osteoarthritis is nothingmore than wearing away that gristle on the end of the bone and instead of havingseven to 10 millimeters of tread, you may have threeto four millimeters of tread. And the swelling caneither be because of fluid, which is an irritation tothe lining of the joint,
or it can be just because of thickening of the lining of the joint, both of which will cause limited motion. The common symptoms with osteoarthritis are more functional. They're difficulty with walking, ascending or descending stairs, particularly descendingstairs where you put
more force across the kneecap area, kneeling, bending,squatting, where again you're loading and compressingthe joint at its extreme, and driving often times where you have to hold that knee in one particular spot. The symptoms of osteoarthritis often times are made worse any time the knee is held in one position orcompressed in one position
for an extended period of time. All of these decrease the amount of motion across the knee and decreasethe amount of lubrication. On physical exam forosteoarthritis we're really trying to evaluate the nature of thepain, swelling and stiffness. We are looking forseveral specific findings. We're looking to see whereyou're pain is located, if your knee is swollen,
