Arthritis, any of more than 100 different diseases causing pain, stiffness, and in most cases, swelling in the joints.Arthritis affects people of both sexes and of all races, socioeconomic levels, and geographic areas.Osteoarthritis is the most common type of knee arthritis.
Also called wear-and-tear arthritis or degenerative joint disease, osteoarthritis is characterized by progressive wearing away of the cartilage of the joint. As the protective cartilage is worn away by knee arthritis, bare bone is exposed within the joint.
Knee arthritis symptoms tend to progress as the condition worsens. What is interesting about knee arthritis is that symptoms do not always progress steadily with time. Often patients report good months and bad months or symptom changes with weather changes.
This is important to understand because comparing the symptoms of arthritis on one particular day may not accurately represent the overall progression of the condition.The most common symptoms of knee arthritis are:pain with activities, limited range of motion, stiffness of the knee, swelling of the joint, tenderness along the joint, a feeling the joint may "give out", deformity of the joint (knock-knees or bow-legs).
Rheumatologists, physicians who diagnose and treat arthritis and related conditions, use a variety of diagnostic techniques. The first step is a thorough history and physical examination, during which the doctor questions the patient about symptoms and medical history to learn about potential exposure to infectious agents or a family history of arthritis.
The patient is examined to determine the pattern of joints affected. With this information, rheumatologists are usually able to make a diagnosis. Laboratory tests are used to help diagnose inflammatory arthritis.
For example, a blood test called erythrocyte sedimentation rate measures how quickly red blood cells cling together and fall to the bottom of a test tube. When there is inflammation in the body, red blood cells sink faster.
This test lets physicians evaluate how severe the inflammation is. Rheumatologists also test a patient's blood or synovial fluid for the presence of specific antibodies-disease-fighting agents activated in the body by infections.
