Knee The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or kneecap, and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower leg.

Patellar Fracture WHAT YOU NEED TO KNOW: A patellar fracture is a break in your kneecap. 1  Nondisplaced fractures are broken pieces of bone that stay in line. 2  Displaced fractures are broken pieces of bone that move out of line.  Open fractures involve a break in the skin that covers the kneecap.

Patella fracture A fracture of the patella seen on a lateral view. A patella fracture is a fracture of the kneecap, which is one of the most common knee injuries. It is usually the result of a hard blow to the front of the knee. Treatment options for patella fracture include nonsurgical and surgical options, depending on the type of fracture.

- Knee. The knee is a complex pivotal hinge joint that connects the bones in the upper and lower leg, comprised of muscle, ligaments, tendons, and the meeting of four bones: the femur, tibia, fibula, and patella.It is the largest joint in the body.Read More.n Depth: Knee. The knee is a complex joint that flexes, extends, and twists slightly from side to side. The knee is the meeting point of the femur (thigh bone) in the upper leg and the tibia (shinbone) in the lower leg.

- The patella is the small ovoid shaped bone located at the front of the knee (stifle) joint. It is located. within the tendon of the powerful quadriceps muscle and slides within a groove on the lower end of. the femur, known as the femoral trochlea. Patella luxation occurs when the patella slips out of this. groove.

Anatomy Because your kneecap (patella) acts like a shield for your knee joint, it can easily be broken. Falling directly onto your knee, for example, is a common cause of patellar fractures. These fractures are serious injuries and often require surgery to heal. Over the long term, they may cause arthritis in the knee.Anatomy. The patella is a small bone located in front of your knee joint — where the thighbone (femur) and shinbone (tibia) meet. It protects your knee and connects the muscles in the front of your thigh to your tibia.pen fracture. In this type of fracture, the skin has been broken and exposes the bone. These injuries often involve much more damage to the surrounding muscles, tendons, and ligaments. Open fractures have a higher risk for complications and take a longer time to heal.

Knee Joint On the anterior surface of the knee, the patella is held in place by the patellar ligament, which extends from the inferior border of the patella to the tibial tuberosity of the tibia. Posteriorly, the oblique popliteal ligament and arcuate popliteal ligament join the femur to the tibia and fibula of the lower leg.

Prepatellar Bursitis Prepatellar bursitis (also referred to as patellar bursitis) is a painful condition affecting the front of the kneecap (patella). The prepatellar bursa is usually very thin and serves as a cushion between the patella and your skin, protecting your kneecap and the soft tissue that holds it is place.

Bones of the Lower Limb - Listed in Proximal to Distal Order the patella is a sesamoid bone in the tendon of the quadriceps femoris muscle; it provides a protective function by withstanding the grinding forces of the quadriceps femoris tendon against the patellar surface of the femur, especially in full knee flexion: tibia : the bone on the medial side of the leg

- Chondromalacia patella is abnormal softening of the cartilage of the underside the kneecap (patella). It is a cause of pain in the front of the knee (anterior knee pain). Chondromalacia patella is one of the most common causes of chronic knee pain. Chondromalacia patella results from degeneration of cartilage due to poor alignment of the kneecap (patella) as it slides over the lower end of the thighbone (femur). This process is sometimes referred to as patellofemoral syndrome.

Cartilage of the Knee A meniscus is a piece of cartilage that acts as a shock absorber between bones. It stabilizes the joints by evenly distributing the load across the joint area. In the knee, the crescent-shaped menisci are in between the ends of the upper (femur) and lower (tibia) leg bones.artilage is a type of firm, thick, slippery tissue that coats the ends of bones where they meet with other bones to form a joint.

- Email. Print. Often called runner's knee, chondromalacia patella is a common condition causing pain in the kneecap. The patella is covered with a layer of smooth cartilage, which normally glides across the knee when the joint is bent.ymptoms of chondromalacia include knee tenderness and pain that increases after sitting for a prolonged period of time, using stairs or getting out of a chair. There may also be a grating or grinding sensation when the knee is straightened.

Bones The fourth bone of the knee is the patella. 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.

Patellar Subluxation: What to Do About an Unstable Kneecap The patella, or kneecap, is one of three bones that forms the knee joint. Each of these bones has a protective layer of cartilage where their surfaces come into contact. The patella is also enveloped by a tendon. This tendon connects the quadriceps muscle of the thigh to the shinbone (tibia) below the knee.

Physical Therapy in Corpus Christi for Knee Issues Bipartite patella is a congenital condition (present at birth) that occurs when the patella (kneecap) is made of two bones instead of a single bone. Normally, the two bones would fuse together as the child grows but in bipartite patella, they remain as two separate bones.
