What does Tricompartmental mean?
Tricompartmental refers to the three parts, or “compartments,” that make up your knee. There is some crossover between compartments: The medial compartment includes the spot where your thigh bone meets your shin bone and the space around it on the inside of your leg (the side closest to the other knee).
What is the medical name for the knee bone?
Patella: The medical name for the kneecap. The patella is what is technically called a sesamoid bone, which is a bone situated within the tendons of a muscle.
What is it called when your knee bone sticks out?
Patellar tracking disorder means that the kneecap (patella) shifts out of place as the leg bends or straightens. In most cases, the kneecap shifts too far toward the outside of the leg.
What are the 3 compartments of the knee?
The knee can be divided into three compartments:
- The medial compartment.
- The lateral compartment.
- The patello-femoral compartment.
Who is OA?
Osteoarthritis (OA), the most common musculoskeletal condition, is a long-term chronic disease involving the thinning of cartilage in joints which results in bones rubbing together, creating stiffness, pain, and impaired movement.
What is bifid patella?
A bipartite patella forms when a portion of the patella does not completely heal along the bony edges of the patella. Most commonly, this is in the upper and outer (superolateral) portion of the patella. Bipartite patella is quite common, usually asymptomatic, and is found in 2% of the population on x-rays.
What is Osgood Slatus?
Osgood-Schlatter disease is a condition that causes pain and swelling below the knee joint, where the patellar tendon attaches to the top of the shinbone (tibia), a spot called the tibial tuberosity. There may also be inflammation of the patellar tendon, which stretches over the kneecap.
What is patella baja?
Congenital patella baja refers to a patella distal in relationship to the femoral trochlea and present since an early age. Acquired patella baja may occur secondary to distal positioning of the patella relative to the femoral trochlea or shortening of the patellar tendon, as a result of trauma or surgery.
What is multipartite patella?
Multipartite patella is an uncommon congenital abnormality that represents normal variant pathology and is a result of a failure of ossification during development. It is most commonly diagnosed as an incidental finding.
What is the small bone at the front of the knee?
Patella: aka kneecap is the small bone at the front of the knee. The two largest knee bones, the femur and the tibia, join together to form what is known as the tibiofemoral joint, and at the front of the knee the kneecap rests in a groove on the front of the femur, known as the patellofemoral joint.
What is the other type of cartilage in the knee called?
The other type of cartilage in the knee joint is called the meniscus. The meniscus is a shock absorber that sits between the end of the thigh bone and the top of the shin bone. 2 Ligaments are structures that connect two bones together. There are four major ligaments that surround the knee joint.
What are the different places in the knee joint for knee replacement?
Knee joint replacement – These pieces may be placed in the following places in the knee joint 1 Lower end of the thigh bone — This bone is called the femur. 2 Upper end of the shin bone, which is the large bone in your lower leg — This bone is called… 3 Back side of your kneecap — Your kneecap is called the patella.
What is the function of the kneecap bone?
Commonly referred to as the kneecap, this nearly heart-shaped bone at the center of the knee helps extend the knee and protect the joint from impact. A tendon at the top of the patella and a ligament at the bottom hold the bone in place. As the knee bends, the patella slides along a groove in the femur.
