Knee Pain – Myths and Facts
“Individuals with knee pain should decrease their physical activity as this places added pressure on joints and increases the pain.”
MYTH - An active lifestyle with plenty of exercise is best for all bodies—including those that are experiencing knee pain. Those who suffer from knee pain are often at increased risk of not getting enough movement in their daily lives due to their aches and pains, but decreased mobility can actually cause greater joint issues later on. Individuals experiencing joint pain should opt for types of movement that don’t require repeated impact on the joints, for example, swimming or a stationary bike. The more you move, the more likely you are to maintain your current range of motion, knee pain or not—and exercise is key in helping maintain an ideal weight, which is integral to joint health as well.
“Strength exercises are damaging to individuals with knee pain and should be avoided.”
MYTH - Initially, the aim is to let pain and swelling settle but we don’t want to avoid using the knee completely as this can lead to increased stiffness and longer term issues. Activation of the muscles around the knee after pain or injury is crucial for recovery as this prevents the knee joint itself from doing all the work. Simple exercises such as a squat or bridge will strengthen the quadriceps and hamstrings.
“Weight has an impact on knee pain.”
FACT - Research has shown that those with a higher body mass index are more likely than those with a normal BMI to report knee pain and accompanying limitations. Excess weight puts additional stress on weight-bearing joints, such as the knees. Inflammatory factors associated with weight gain can also contribute to trouble in other joints. The more weight on the joint, the more wear and tear on the cartilage which can lead to osteoarthritis. With osteoarthritis, the cartilage “cushion” within a joint degenerates. Bones then rub against each other, causing irritation, pain and swelling.
“When walking on level ground, the force on your knees is equivalent to…”
1.5 times your body weight?
2 times your body weight?
3 times your body weight?
When you walk across level ground, the force on your knees is the equivalent of 1½ times your body weight. Add an incline, and the pressure is even greater. When going up and downstairs, the force on each knee is two to three times your body weight and four to five times your body weight when you squat to tie a shoelace or pick up an item you dropped.
“Knee pain is always the result of an earlier injury, whether from sports, trauma or repetitive strain.”
MYTH - Although knee pain can be caused by an earlier injury or trauma, this is not always the case. Knee pain can also be caused by conditions such as osteoarthritis, as mentioned earlier.
