Knee

The joint surface is covered by a smooth articular surface that allows pain-free movement in the joint. Arthritis is a general term covering numerous conditions where the joint surface or cartilage wears out. This surface can wear out for several reasons; often the definite cause is not known.

Knee osteoarthritis (OA) is a degenerative joint disease that occurs when the cartilage in the knee joint gradually wears away. Cartilage is a smooth, slippery tissue that cushions the ends of bones and helps the joint move smoothly.

A fracture is a condition in which there is a break in the continuity of the bone. In younger individuals, these fractures are caused by high energy injuries, as from a motor vehicle accident. In older people, the most common cause is a weak and fragile bone.

Trauma to the knee can injure one or more tissues of the knee joint, such as ligaments, tendons, cartilage, bones, and muscles. These injuries can result from a fall, a forceful twisting motion, or a high-impact event like a motor vehicle accident. Common knee injuries include fractures, dislocations, tears, and sprains.

Knee sprain is a common injury that occurs from overstretching of the ligaments that support the knee joint. A knee sprain occurs when the knee ligaments are twisted or turned beyond its normal range, causing the ligaments to tear.

Meniscal tears are one of the most common injuries to the knee joint. It can occur at any age but are more common in athletes involved in sports. The meniscus has no direct blood supply and for that reason, when there is an injury to the meniscus, healing is difficult.

Knee pain is a common condition affecting individuals of various age groups. It not only affects movement but also impacts your quality of life. An injury or disease of the knee joint or any structure surrounding the knee can result in knee pain.

The knee joint is one of the largest joints in the body. This highly complex joint is supported and stabilized by several tissues, including ligaments, tendons, muscles, and cartilage. When these structures are damaged or weakened, the knee may become unstable, causing a feeling of giving way, weakness, or difficulty with everyday activities.

A meniscal tear is a common knee injury in athletes, especially those involved in contact sports. A sudden bend or twist in your knee causes the meniscus to tear. Elderly people are more prone to degenerative meniscal tears as the cartilage wears out and weakens with age.

The knee is a complex joint that consists of bone, cartilage, ligaments, and tendons that help in your joint’s movements.  The knee is a hinge joint made up of two bones, the thighbone (femur) and shinbone (tibia). Ligaments are tough bands of tissue that connect one bone to another bone. The ligaments of the knee stabilize the knee joint.

The patellar tendon works together with the quadriceps muscle and the quadriceps tendon to allow your knee to straighten out. Patella tendon rupture is the rupture of the tendon that connects the patella (kneecap) to the top portion of the tibia (shinbone).

Knee dislocation is a condition that occurs when the bones that form the knee joint, namely the femur or thigh bone get separated from the shin bone. This can cause serious damage to the nerves, blood vessels, and ligaments surrounding the knee, leading to a decline in strength and overall health of the leg.

Articular or hyaline cartilage is the tissue lining the surface of the two bones in the knee joint.  Cartilage helps the bones move smoothly against each other and can withstand the weight of the body during activities such as running and jumping.

Patellar tendonitis, also known as "jumper's knee", is an inflammation of the patellar tendon that connects your kneecap (patella) to your shinbone. This tendon helps in extension of the lower leg.

Stress fractures of the patella or knee are very rare. Approximately two out of 10,000 athletes may experience a patella stress fracture. Initial symptoms include activity-related pain and then a fatigue stress fracture after minor trauma.

Injury to more than one knee ligament is called a complex or multiligament knee injury and may occur during sports or other physical activities. The knee joint is one of the largest and complex joints in your body.
