Joints are the areas where two or more bones satisfy. A lot of joints are mobile, allowing the bones to relocate. Essentially, the knee is two lengthy leg bones held together by ligaments, muscles, and tendons. Each bone end is covered with a layer of cartilage material that soaks up shock and secures the knee.
There are two teams of muscles involved in the knee, including the quadriceps muscle, located on the front of the thighs, which align the legs, as well as the hamstring muscles, located on the back of the thighs, which flex at the knee or the leg.
Ligaments are tough cables of connective tissue that link muscles to bones. Tendons are rubber bands of tissue that attach bone to bone. Some ligaments of the knee supply stability and protection of the joints, while various other ligaments limit ahead as well as backward activity of the tibia, or shin bone.

The knee contains the following:
- Shin. This is the shin bone or larger bone of the lower leg.
- Patella. This is the kneecap.
- Thigh. This is the thighbone or upper leg bone.
- Cartilage. A type of tissue that covers the surface area of a bone at a joint. Cartilage helps in reducing the friction of motion within a joint.
- Ligament. A kind of difficult, elastic connective cells that surrounds the joint to give support and limit the joint’s motion.
- Synovial membrane. A cell that lines the joint as well as seals it right into a joint pill. The synovial membrane layer produces synovial fluid, a clear, sticky fluid, around the joint to lube it.
- Tendon. A kind of hard connective tissue that connects muscles to bones as well as helps to manage the movement of the joint.
- Meniscus. A bent part of cartilage in the knees as well as various other joints that function as a enhances call area, shock absorber, as well as grows the knee joint.
