Knee Anatomy Facts And Myths
The knee anatomy consists of a collection of bones, ligaments, and cartilage. When used in conjunction these components are integral to many of the body’s movements. The main bones involved in the knee joint anatomy are the femur, fibula, tibia, and patella. The femur is the bone of the upper leg and its distal end connects to the knee by ligaments. The fibula and tibia are the bones of the lower leg and use the same types of connections to the knee as does the femur. The patella, or kneecap, is a bone located in the front of the knee. Collateral and cruciate are the two types of ligaments found in the knee. In addition, there is much cartilage in the joint that helps with the functional anatomy of the knee. Yet another part of the area is the knee joint capsule. This is the watertight space inside of the joint that allows for bone and ligament movement.
The human knee anatomy is the simple most important joint in a person’s ability to walk. The bones that meet in the knee joint are covered in articular cartilage that prevents excessive rubbing and grinding between the bones. Also, meniscus cartilage exists to serve as shock absorbers from pressures and impact. The femur bone and the knee joint in general shoulder the majority of a person’s weight while in a standing position or walking, thus these cartilage pads are very important to comfort while in movement. The collateral ligaments (medial and lateral) that connect the femur to the fibula and tibia are responsible for governing the amount of side to side movement that can safely be done by the knee. Additionally, they stop the tibia moving too far backwards towards the femur. The cruciate ligaments (anterior and posterior) prevent both excessive rotation and overstretching of the knee in forwards and backwards motions.
The most common injuries to the knee joint anatomy occur while in movement and are frequent among athletes. The range of complications can vary widely from something as simple as bruising to complete anterior cruciate ligament tears. The more serious ACL tears are known to be twice as frequent among women than with men. In these types of injuries, an audible sound can sometimes be heard and recovery from the tear can take an extended period of time. In many cases, patients will need reconstruction surgery in which the entire ligament is replaced. Other potential causes of damage to the functional anatomy of the knee are motor vehicle accidents, slips, falls, and traumatic impact.
The human knee anatomy is very important to know as it is used on a daily basis and injuries can be common. Prepared with the proper knowledge of how the knee joint functions can help athletes and other people be more aware of how injuries to the knee anatomy are caused and the best way to prevent injuries from happening.
