Anatomy of The Knee Joint
The knee joint's main function will be to bend, straighten, and bear the body weight of the body and also the ankles and hips. Your leg, more than just a basic hinged joint, however, also twists in addition to rotates. In order to perform these types of actions and to support the entire body while doing so, the knee relies on many structures including our bone tissues, ligaments, tendons, and cartilage.
Bones
The knee joint involves some bones.
The thighbone or femur comprises the most effective portion of the joint.
One of several bones from the lower lower-leg (or leg area), the shin, affords the bottom weight-bearing percentage in the joint.
The kneecap or patella rides throughout the front of the femur.
The bone from the calf, the actual fibula, is not involved in the weight-bearing portion of the leg joint. It only provides tendon attachments intended for stability.
Ligaments
Ligaments are dense fibrous rings that connect bones to one another.
The knee includes four significant ligaments, all of which connect the femur towards the tibia:
The medial collateral ligament (MCL) besides lateral collateral ligament (LCL) located throughout the inner (medial) and outer (lateral) sides with the knee provide medial and lateral stability towards the knee.
Tendons
Tendons are fibrous bands much like ligaments.
Instead of joining our bones to various other bones as ligaments attain, tendons connect muscles to your bones.
The 2 important tendons from the knee are (1) the quadriceps tendons connecting the quadriceps muscle, which lies from the front of the " leg ", to the patella and (2) your patellar tendon connecting the patella towards the tibia (technically this is usually a ligament because it attaches 2 bones).
The quadriceps and patellar tendons are occasionally called the extensor process, and along with the quadriceps muscle they aid lower-leg extension (straightening).
Cartilage
Cartilaginous structures called menisci (one is usually a meniscus) line the superior tibia and lie relating to the actual tibia and the 2 knuckles in the bottoom in the femur (called the real femoral condyles).
The menisci's primary job will be to provide cushioning for the leg joint.
Bursae
Bursae (one is usually a bursa) are fluid-filled sacs that help cushion the knee. The knee contains 3 essential sets of bursae:
The prepatellar bursae lie while watching patella.
The anserine bursae is around the inner side of the leg about 2 inches below your joint.
The infrapatellar bursae are normally found underneath the patella.
Knee ache is incredibly widespread. In the united claims, it's responsible for about 1/3 on most doctors’ visits for muscle besides bone pain. Knee pain is usually a special problem for athletes -- over half of all athletes endure that annually.
Some of the most common reasons behind knee pain are swollen or even torn ligaments, meniscus (cartilage) slots, and runner's knee. But the knee is usually a complex joint, and there's plenty more that may go wrong.
