The knee is the most frequently injured joint in the body for 3 reasons:
a. It is the largest joint in the body
b. It is the most complex
c. It is the most unstable
It's also known that women are more likely to have issues with their knees than men.
One reason is due to a greater Q angle in women. The Q angle (as seen in the image) tends to be greater in women because the female pelvis is wider. This increase means there is a displacement of the knee. The greater the Q angle, the greater the displacement, the more stress on the joint structure.
But just because us women are more prone to knee injuries doesn't mean we just have to lie back, accept the fact, and let our knee problems rule us. This simply means that we need to work a little harder and a little smarter at making our joints more stable.
