Examples of patella in the following topics:
-
- The patella (knee cap) is the bone between the fibula and femur.
- The patella or knee cap is the bone between the fibula and femur.
- Each leg has a patella to protect its knee joint.
- The patella serves two
functions:
- The apex of the patella
faces inferiorly and connects to the tibia tuberosity through the patella
ligament that attaches to the anterior surface.
-
- Patellofemoral pain syndrome is discomfort originating from the contact of the posterior of the patella (kneecap) with the femur.
- Patellofemoral pain syndrome (PFPS) is a syndrome characterized by pain or discomfort seemingly originating from the contact of the posterior surface of the patella (back of the kneecap) with the femur (thigh bone).
- The result is thinning and softening of the articular cartilage under the patella and/or on the medial or lateral femoral condyles, synovial irritation and inflammation, and subchondral bony changes in the distal femur or patella known as "bone bruises".
- Quadriceps strengthening is commonly suggested because the quadricep muscles help to stabilize the patella.
- This image shows the relationship of the patella to the femur.
-
- The patella is the attachment point for the
quadriceps femoris muscle and is the attached by a ligament to the tibia.
- The patella
additionally protects the knee joint from damage.
- Attachments: The vastus
lateralis, intermedius, and medialis originate from the femur and attach to the
patella.
- The rectus femoris originates from the pelvis and attaches to the
patella.
- Actions: Extends the lower leg
at the knee joint and stabilizes the patella.
-
- The tibia, or shin bone, spans the lower
leg, articulating proximally with the femur and patella at the knee joint, and
distally with the tarsal bones, to form the ankle joint.
- On the anterior surface of the proximal region and inferiorly
to the condyles is the tibial tuberosity to which the patella ligament
attaches.
- The fibula also spans the lower leg, although
proximally it does not articulate with the femur or patella.
-
- The thighs and legs have 8 bones: The left and right femur
(thigh, 2), patella
(knee, 2), tibia
(2) and fibula
(leg, 2).
- These consist of the femur, patella, tibia, fibula, tarsal
bones, metatarsal bones, and phalanges.
-
- The femur articulates proximally
with the acetabulum of the pelvis to form the hip joint, and distally with the
tibia and patella to form the knee joint.
- Two rounded regions, termed the medial and lateral condyles, articulate
with the tibia at the most anterior projection of the patella.
-
- The bones of the lower limb are the femur (thigh bone), patella (kneecap), tibia and fibula (bones of the leg), tarsals (bones of the ankle), and metatarsals and phalanges (bones of the foot) .
- At the distal end, the femur, tibia, and patella form the knee joint.
- The patella, or kneecap, is a triangular bone that lies anterior to the knee joint; it is embedded in the tendon of the femoral extensors (quadriceps).
- The lower limb consists of the thigh (femur), kneecap (patella), leg (tibia and fibula), ankle (tarsals), and foot (metatarsals and phalanges) bones.
-
- Thigh and leg (eight bones) - The thigh and leg consist of the femur (two bones that comprise the thighs), Tibia (two bones), Patella (two bones that are the knees), and Fibula (two bones).
- The femur, tibia, patella, and fibula are all a part of the appendicular skeleton.
-
- In this example, the condyles of the femur join with condyles of tibia and the saddle joint, where the lower end of the femur joins with the patella.
-
- An example is the patella (knee cap) located in the
patellar tendon.
