Knee Biomechanics and Mobility

This twist is actually quite common, and for some - it can lead to knee agitation and pain. I’ve explored a variety of exercises over the years to help clients “untwist” knees. What does optimal knee movement look like? Flexion: When the knee goes into flexion, the tibia (shin bone) has to internally rotate and the fibula on the side has to posteriorly glide. When those motions happen, it allows for good flexion, and the femur can posteriorly roll on the tibia. Extension: When the knee extends the tibia is externally rotating, the femur is anteriorly rotating / externally rotating, and the fibula has to glide anteriorly. One of the most common presentations I see is a pelvis oriented more forward, in either an extension or swayback pattern. This presentation often leads to more internal rotation of the femur, a result of pelvis and rib cage position. This is twist number one. In response to that twist, I’ll often see a tibia in more external rotation. This is twist number two. This combination of femur in internal rotation + tibia in external rotation is often the twist I see that causes knee agitation or pain. The foot can also have different presentations 1. Everted position of calcaneus + rigid mid-foot 2. Everted calcaneus + flat mid-foot with possible drop of navicular 3. Rigid foot throughout + inverted Everyone’s bodies orient differently, adapting to the demands of everyday life and sport. But, the tibial rotation exercises in this week’s video can support the knee, hip, and foot health of most people.
