Osteoarthritis is the most common form of arthritis and is characterized by pain in the joint, stiffness, and even loss of movement. It is a degenerative joint disease and slowly evolves as part of the aging process. Osteoarthritis has been around for a very long time, going back as far as the dinosaur bones and Egyptian mummies which show evidence of the disease. The disease is classified as a non-inflammatory type of arthritis; but recent research shows this not to be true. Early on in the disease inflammation is usually not a problem; but as the cartilage starts to wear away and fragment, the loose pieces of cartilage cause an immune response and inflammation.
Osteoarthritis can be caused by an injury to the joint, repetitive strain on a joint, or it can be passed on through our genes. The joints most commonly affected with the disease are the hands, the hips, the lower back, knees and the big toes.
Pain is the most predominant feature of osteoarthritis. Early in the disease, pain will accompany movement, is aggravated by prolonged activity, and can be made better with rest. Pain is often caused by stretching of the lining of the bone at the sites of new bone growth. The pain could also be from nerve irritation or compression.
A sprained knee is an injury that no one wants to experience, however, sports and daily physical activity sometimes contribute to such an injury. If we take the proper precautions necessary we can limit our chances of experiencing a sprained knee. We will explore some of the methods used to help prevent such an injury and ensure that when you play sports or are involved in a physical activity you try to limit your chances of getting injured.
One of the most productive exercises that one can perform to prevent a sprained knee is to make sure an individual stretches before engaging in sports or physical activity. Stretching your legs and body enables you to get accustomed to certain positions which contribute to flexibility of your legs and knees. This flexibility will help in avoiding injuries especially when the knee is subjected to certain unorthodox positions.
It is also important that when playing sports, you have the proper footwear and attire. Certain activities such as football and soccer require special footwear and shoes. These shoes and attire assist in ensuring you have strong placement of your feet in the turf or grass that you are playing in. It helps to prevent injuries by ensuring that your footwear is designed to handle the terrain of the environment that you are playing in. Another important factor is ensuring that the body weight on your knees does not bear a heavy load.
