This is how your knee moves...#bones #bonesetting #knee

The knee joint is a remarkable hinge joint that allows movement in two primary directions: flexion and extension. Let's explore how it works:

1. Flexion:
- When you bend your knee, such as when you lift your lower leg towards your thigh, you are performing flexion.
- The hamstrings (muscles at the back of your thigh) contract to initiate this movement.
- The quadriceps (muscles at the front of your thigh) relax during flexion.

2. Extension :
- Straightening your knee is called extension.
- The quadriceps contract to extend the knee, while the hamstrings relax.
- This action is essential for activities like standing up from a chair or walking.

3. Rotation:
- Although the knee primarily moves in flexion and extension, it also allows a small amount of rotation.
- This rotation occurs when the knee is slightly bent.
- The menisci (cartilage pads) within the knee joint help facilitate smooth movement during rotation.

Remember, the knee joint is a complex structure involving bones (femur, tibia, and patella), ligaments (such as the anterior cruciate ligament and posterior cruciate ligament), tendons, and muscles. It's crucial for stability, weight-bearing, and locomotion. 🦵💪.
