Active people will understand that different movements place various levels of strain on the knee joints. The knees will take force from both above and below. A person’s total body weight will impact the downward load, and the surface that the feet are walking on (along with the activity being performed) will impact knee pressure from below. Although studies use various techniques and it is difficult to record accurately, the studies carried out to date suggest that significant pressure is applied to the knee during everyday activities such as walking, running and exercise. Forces transmitted across the knee joint during normal walking range between 2 and 3 times body weight. This is in part due to the kinetics of acceleration, the high moments generated at the knee, and simultaneous contraction of multiple muscles. Walking downhill with significant knee flexion (bending) can increase this load to 8 times bodyweight. Because it’s subjected to forces up to 8 times bodyweight with running and jumping, the cartilage underneath the kneecap is among the thickest in the body. This cartilage is a natural shock absorber and protects the bony surfaces of the joint from stress. While cartilage doesn’t have any nerve supply, the underlying bone is highly innervated and becomes vulnerable when no longer protected by the padding of the cartilage. How can insoles help reduce knee pressure? Performance insoles can help to reduce knee pressure in a number of ways. Even the simplest insoles will add a layer of padding between the ground and the feet which will help to absorb some of the pressure. Specialist insoles use technology that works hard to diffuse even more of this load. Specifically, the best insoles provide structural support to correct poor gait which will allow the joints to align optimally to reduce knee pressure. They are also created with high-tech materials that work to provide shock absorption and impact protection. The multiple bodyweight pressure on knees can be measurably reduced by wearing performance insoles.
