Knee osteoarthritis is a degenerative disease that causes the wear and tear of different components in the joint, such as cartilage or the synovial membrane.
This pathology can produce functional incapacity in patients, although symptoms are most commonly limited to annoyances that persist throughout the day.
During the disease’s development, the erosion of the articular cartilage can alter the bone opposite to the joint, causing this wear and tear process to begin.
As a result, there may come a time when the cartilage disappears and pain appears. As the cartilage disappears, the bone reacts and grows on the sides (osteophytes) producing the deformation of the joint.
Joints related to the musculoskeletal system are the most common cause of medical consultation.
According to data from the Gaceta Médica de México,85% of patients with this condition are over 65 years old.
It is caused by the deterioration of the articular cartilage, which covers the bony ends that together give rise to the joints, the components of the skeleton that allow movement.
The articular cartilage is essential for the proper functioning of the joint, as it is the surface that cushions and allows sliding between the bone ends that form any joint.
The most common causes are obesity, intense physical activity, a sedentary lifestyle and congenital conditions.
Treatment for knee osteoarthritis begins with changing daily activities and a weight-control diet. Conservative measures are also used, such as the use of insoles, physical therapy, rehabilitation and medications, such as infiltrations with hyaluronic acid, platelet-rich plasma, analgesics, etc.
