Knee Anatomy, Function and Popular Issues. Anatomical Terms

The leg joint is really a synovial joint which links the femur (thigh bone tissue), the bone that is longest in the torso, to your tibia (shin bone tissue). There are two primary main bones into the leg: 1) the tibiofemoral joint where the tibia meet up with the femur 2) the patellofemoral joint in which the kneecap (or patella) satisfies the femur. Both of these bones come together to create a modified hinge joint that enables the leg to fold and straighten but additionally to turn slightly back and forth.

The leg joint may be the biggest joint in the body. It really is at risk of damage because it bears a massive number of stress while supplying movement that is flexible. Once we walk, the load on our knees is corresponding to 1.5 times the body fat. Whenever stairs that are climbing is equivalent to 3-4 times your body weight. Whenever we squat, the strain on our knees increases to about 8 times the body fat!

Anatomical terms let us explain the physical human anatomy and the body motions more exactly

In the place of a medical practitioner just stating that “the patient’s knee hurts”, they are able to state that “the patient’s leg hurts anterolaterally” to specify where precisely into the leg you may be having discomfort. Determining particular aspects of discomfort helps you to guide the steps that are next therapy or work-up. Listed here are some anatomic terms health practitioners used to explain location (as put on the leg):

  • Anterior — if facing the knee, this is actually the front side associated with knee
  • Posterior — if facing the leg, here is the relative straight back of this leg. Then it would refer to the side of the patella closest to the femur if used to describe the patella (knee cap.
  • Medial — the relative region of the leg this is certainly closest to another leg, in the event that you place your knees together, the medial sides of every leg would touch
  • Lateral — the medial side associated with leg that is farthest through the other leg (reverse for the medial part)
  • Abduction — move away through the human body (increasing the leg far from midline in other terms. towards the medial side)
  • Adduction — move toward the human body (bringing down the leg toward midline in other words. through the part)
  • Proximal — located nearest to your point of accessory or guide, or center regarding the human anatomy
    • instance: the leg is proximal towards the ankle
  • Distal — located farthest through the point of accessory or guide, or center regarding the human body
    • instance: the ankle is distal towards the knee
  • Substandard — located beneath, under or below
  • Superior – located above

Structures frequently have their reference that is anatomical as of these title, especially if there are more comparable structures near by. For example, there are two main menisci (or meniscus, single) within the leg. As a result, these are typically called the medial meniscus and meniscus that is lateral. Consequently, the meniscus that is medial make reference to the meniscus regarding the inside the leg (for example. closest to another knee).

Structures associated with the Knee

Once more, the leg joint is really a hinge type joint. The the main home that keeps it guaranteed to your wall surface and permits it to close open and is named a hinge. A lot of the motion allowed by the leg could be the type that is same of permitted by way of a home hinge. It also enables a little quantity of rotational motion.

If you believe for the leg in levels, the deepest layer is bone tissue and ligaments, then ligaments associated with joint capsule, then muscles on the top. Different nerves and blood vessels provide you with the muscle tissue and bones associated with the leg.
