Osteoarthritis of the Knee Fernando Gomez, MD orthopedic Surgical 2015
Osteoarthritis is a common problem for many people. Osteoarthritis is sometimes referred to as "degenerative disease", or wear-and-tear arthritis. The main problem in osteoarthritis is degeneration of the articular cartilage that the joint. This results in areas of the joint where bone against bone. Bone spurs may form around the joint as body's response. Osteoarthritis may result from an injury knee earlier in life. Fractures involving the joint surfaces, instability from ligament tears, and meniscal injuries can abnormal wear and tear of the knee joint. Not all cases of osteoarthritis are related to prior injury, however. Research has shown that some people are prone develop osteoarthritis, and this tendency may be genetic. Osteoarthritis develops slowly over several years. The symptoms of osteoarthritis are mainly pain, swelling, and stiffening of the knee. The pain of osteoarthritis is worse after activity. Early in the course of the disease, may notice that your knee does fairly well while walking, after sitting for several minutes the knee becomes stiff painful.
As the condition progresses, pain can interfere with even daily activities, In the late stages, the pain can be continuous and even affect sleep patterns. This pain probably does not come from the covering of the joint, the articular cartilage, because this tissue does not have a nerve supply. There is still some confusion about where the pain in osteoarthritis actually comes from. Sources of pain may be due to: 1. Inflammation in the lining of the joint, called the synoviurn. 2. Small fractures in the bone under the cartilage, the subchondral bone. 3. Pressure from blood in the area. 4. Stretching of nerve endings over a bone spur (osteophyte). 5. Degenerative tears in the meniscus cartilage. 6. Loose bone chips in the joint.

Diagnosis The diagnosis of osteoarthritis can usually be made on the basis of the initial history and examination. X-Rays are very helpful in the diagnosis and may be the only special test required in the majority of cases. In some cases of early osteoarthritis, the X-rays may not show changes typical of osteoarthritis. It is not always clear where the pain is coming from.
