In humans and other primates, the knee joins the thigh with the leg and consists of two joints: one between the femur and tibia (tibiofemoral joint), and one between the femur and patella (patellofemoral joint). It is the largest joint in the human body.
What type of joint is in knee?
The knee joint is a hinge joint, meaning it allows the leg to extend and bend back and forth with minimal side-to-side motion. It is comprised of bones, cartilage, ligaments, tendons, and other tissues.
What is the main knee joint called?
Knee joint: The knee joint has three parts. The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (the patella) joins the femur to form a third joint, called the patellofemoral joint.
Is knee joint a hinge joint?
The knee continues to function primarily as a hinge joint.
Which is a hinge joint?
Hinge joints are a type of joint that functions much like the hinge on a door, allowing bones to move in one direction back and forth with limited motion along other planes. The fingers, toes, elbows, knees, and ankles contain hinge joints. Hinge joints are complex and contain many muscles and tissues.
21 related questions foundWhat are ligaments?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.
What is a cartilage?
Cartilage a strong and smooth substance made up of “chondrocytes,” or specialized cartilage cells, that produce a matrix of collagen, proteoglycans (a special type of protein) and other non-collagenous proteins. These materials help cartilage attract water and give it its shape and specific properties.
Whats the back of the knee called?
Pain in the back of the knee, called the popliteal fossa, is common, but there is a wide range of causes, ranging from ligament injury to arthritis.
Where is your knee joint?
The knee is one of the largest and most complex joints in the body. The knee joins the thigh bone (femur) to the shin bone (tibia). The smaller bone that runs alongside the tibia (fibula) and the kneecap (patella) are the other bones that make the knee joint.
Where is tibiofemoral joint?
The main weightbearing part of the knee joint is made up of the articulation between the tibia and femur. This is called the tibiofemoral joint. On the inner side is the medial tibiofemoral compartment and on the outer side is lateral tibiofemoral compartment.
Is the knee a synovial joint?
Synovial joints, such as the hip and knee, have a sheath of tissue known as a joint capsule that contains a synovium. This membrane produces a special fluid to lubricate the joint and prevent wear on cartilage while the joint is in motion.
What is the outer knee called?
The lateral collateral ligament (LCL) is on the outer side of your knee. It connects your femur to your calf bone (fibula). The collateral ligaments prevent the knee from moving side to side too much.
Which side is anterior knee?
The lateral side of the knee is the side that is away from the other knee. Structures on the medial side usually have medial as part of their name, such as the medial meniscus. The term anterior refers to the front of the knee, while the term posterior refers to the back of the knee.
What are 3 types of cartilage?
There are three types of cartilage: hyaline, fibrous, and elastic cartilage. Hyaline cartilage is the most widespread type and resembles glass. In the embryo, bone begins as hyaline cartilage and later ossifies. Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis.
What are synovial joints?
A synovial joint is the type of joint found between bones that move against each other, such as the joints of the limbs (e.g. shoulder, hip, elbow and knee). Characteristically it has a joint cavity filled with fluid.
What are cartilaginous joints?
Cartilaginous joints are where the adjacent bones are joined by cartilage. At a synchondrosis, the bones are united by hyaline cartilage. The epiphyseal plate of growing long bones and the first sternocostal joint that unites the first rib to the sternum are examples of synchondroses.
What is the name of the wrist joint?
The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand.
What are the 3 joints of the elbow?
The three joints of the elbow include:
- Ulnohumeral joint is where movement between the ulna and humerus occurs.
- Radio humeral joint is where movement between the radius and humerus occurs.
- Proximal radioulnar joint is where movement between the radius and ulna occurs.
What is the funny bone called?
Funny you should ask. It turns out that your funny bone isn't a bone. It's actually a nerve — one that starts in your spine and travels from your neck, through your elbow and to your fingers (your pinky and ring fingers, to be exact). It's called the ulnar nerve.
What are the 5 ligaments of the knee?

- Posterior Cruciate Ligament (PCL) ...
- Medial Collateral Ligament (MCL) ...
- Lateral Collateral Ligament (LCL) ...

What is a torn ligament in leg?
Recap. A ligament tear is an injury caused by an extreme motion, like a forceful twisting of a joint. A tear usually causes immediate pain and perhaps even a "pop" sound at the site of injury when it occurs. Depending on the severity of the injury, the affected site may become unstable.
Which is a ligament injury?
A sprain is an injury to the band of collagen tissue i.e. a ligament, which connects two or more bones to a joint.
How many joints are in the knee joint?
In humans and other primates, the knee joins the thigh with the leg and consists of two joints: one between the femur and tibia (tibiofemoral joint), and one between the femur and patella (patellofemoral joint). It is the largest joint in the human body.
What are the 6 types of synovial joint?
Synovial joints are often further classified by the type of movements they permit. There are six such classifications: hinge (elbow), saddle (carpometacarpal joint), planar (acromioclavicular joint), pivot (atlantoaxial joint), condyloid (metacarpophalangeal joint), and ball and socket (hip joint).
