Although most traumatic injuries are accidents, people can modify many elements that can
contribute to such injuries. These contributors include unsuitable environment, poor equipment, inadequate warm-up, and lack of previous conditioning
Exercising on a rocky or uneven surface increases the chance of ankle sprains or even dangerous falls, whereas there is less chance of such problems occurring on even ground. Proprioception , the ability to perceive a joint's position, decreases both after an injury to the knee and because of osteoarthritis .This change in proprioception means that a persons response to an unexpected change in the exercise surface may be impaired, resulting in a fall. To worsen the situation, the muscles in the anterior thigh (quadriceps) are often inhibited because of previous injury or the effects of arthritis, decreasing their responsiveness. Keep to even surfaces when you begin your program. The good news is that a regular exercise program results in improved muscular function and balance
Shoes that fit poorly or do not give adequate support also increase the chance of injury. Watch the movement of a woman's ankle when she is walking in heels and you will see side-to-side rocking. The same type of movement occurs in a shoe that fits poorly or does not have a good supportive base, though it is not as noticeable. Such excess movement increases the potential for ankle sprains and foot pain
Lack of warm-up often leads to muscle strains, to which you may already be more susceptible because of your arthritis. Both arthritis and aging make tissues less elastic and more brittle. If a sudden strain is put on such tissues, they are more prone to tear. A good warm-up increases blood flow and tissue temperature in the exercising muscles, which increases the elasticity of the tissues involved. The warm-up also increases neural stimulation to the active muscles, perhaps improving their responsiveness to unusual stresses
Finally, your level of conditioning, especially muscular conditioning, can affect your susceptibility to injury. Muscle weakness in the lower extremities may result in poor balance, and pain from osteoarthritis may accentuate this problem . As mentioned earlier, conditioning also improves joint proprioception, which works with muscles to react to balance changes
