In the knee anatomy, the surfaces of the bones inside the knee joint are covered by two different types of cartilages. At the femoropatellar joint, the patella slides vertically within a groove on the distal femur. 2018/2019. It is usually regarded as a sesamoid bone, developed in the quadriceps femoris tendon. Share. Key Words: knee anatomy, capsular ligaments, cruciate ligaments, knee stability, biomechanics (Sports Med Arthrosc Rev 2011;19:82–92) T he knee can be conceptualized as 2 joints—a tibiofe-moral and a patellofemoral joint. To understand knee problems, you must know the anatomy of this most complex joint. At the femoropatellar joint, the patella slides vertically within a groove on the distal femur. Comments.

The knee joint is a synovial joint which connects the femur (thigh bone), the longest bone in the body, to the tibia (shin bone). The smooth Articular cartilage covers the head of the femur and the tibial plateau inside the knee joint. Anatomy of the knee joint (anterior and posterior views) You can find out more about the anatomy of the knee joint below! Femur round, tibia flat. The knee is considered one of the most complex joints in the human body. Knee Joint. Chapter 8 Joints of the Skeletal System. Because so many sports place extreme stress on the knee, it is also one of the most frequently injured joints. Knee anatomy synovial fluid. As in veterinary anatomy human anatomy is subdivided into macroscopic (or gross) and microscopic anatomy. 2). Synovial Joints. Compromising any of these structures leads to destabilisation and increased risk of injuries. 01. The 3B Scientific® Anatomy Video "Knee Joint" demonstrates the structure of the knee joint. Knee joint stability requires the integration of a complex set of anatomical structures and physiological mechanism. Knee instability has been the focus of large number of studies over the last decade; however, a high incidence rate of injury still exists. (b)–(c) It is supported by the tibial and fibular collateral ligaments located on the sides of the knee outside of the articular capsule, and the anterior and posterior cruciate ligaments found inside the capsule. Knee joint stability requires the integration of a complex set of anatomical structures and physiological mechanism. Describe the structural features of a synovial joint ; Discuss the function of additional structures associated with synovial joints; List the six types of synovial joints and give an example of each; Synovial joints are the most common type of joint in the body (Figure 1).

Comprised of four bones. the joint between the atlas and dens of the axis) Condyloid joints: the oval articular surface of one bone fits into a complementary depression in another (eg. (b)–(c) It is supported by the tibial and fibular collateral ligaments located on the sides of the knee outside of the articular capsule, and the anterior and posterior cruciate ligaments found inside the capsule. Chapter 8 part a provides knowledge of classification of joints, fibrous joints and cartilaginous joints. Joints | Anatomy and Physiology Figure 9.19 Knee Joint (a) The knee joint is the largest joint of the body. knee, interphalangeal joints) Pivot joints: only movement allowed is uniaxial rotation of one bone around its own long axis (eg. protects knee joint; enhances lubrication and nutrition of knee; Accessory or “bipartite” patella: may represent failure of fusion of the superolateral corner of the patella and is commonly confused with patellar fractures. This usually calls for repeated trips to the anatomy laboratory to dissect and study knee anatomy. Feet Human Anatomy Bones Tendons Ligaments And More The backside of the patella is covered with hyaline cartilage along with the front side of the groove on the femur which minimizes the friction as the patella slides.

Knee joint (Articulatio genu) The knee joint is a synovial joint that connects three bones; the femur, tibia and patella.It is a complex hinge joint composed of two articulations; the tibiofemoral joint and patellofemoral joint.The tibiofemoral joint is an articulation between the tibia and the femur, while the patellofemoral joint is an articulation between the patella and the femur. The synovial fluid which lubricates the knee joint is pushed anteriorly when the knee is in extension, posteriorly when the knee is flexed and in the semi flexed knee the fluid is under the least tension therefor being the most comfortable position if there is a joint effusion. The patella is a sesamoid bone incorporated into the tendon of the quadriceps femoris muscle, the large muscle of the anterior thigh.

Synovial (diarthrosis): Synovial joints are by far the most common classification of a joint within the human body. They also act as shock absorbers and ensure smooth movement during motion of the joint. … It is also reflected on to the articular margins of the femur tibia and patella. The knee is commonly considered a hinge joint because its two principal movements are flexion and extension. Figure 6. The ligaments of the knee maintain the stability of the knee.
