Knee Joint01:23

Knee Joint

2.6K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

4.1K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Ankle Joint01:10

Ankle Joint

2.1K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

1.8K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

3.8K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

5.8K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Area of Science:

  • Orthopedic Surgery
  • Anatomy
  • Biomedical Engineering

Background:

  • The intercondylar fossa (IN) is a key anatomical feature at the femur's distal end.
  • It houses critical knee stabilizing structures, including cruciate and meniscofemoral ligaments.
  • Injuries to these ligaments are often linked to alterations in the IN's morphology.

Purpose of the Study:

  • To highlight the importance of understanding intercondylar fossa morphology.
  • To discuss the clinical significance of IN features and their relationship to ligament injury.
  • To emphasize the need for individualized knee joint assessment due to variations.

Main Methods:

  • Review of anatomical descriptions and measurement methods for the intercondylar fossa.
  • Analysis of studies documenting physiological and pathological changes within the IN.
  • Consideration of factors influencing IN shape, such as aging and sex differences.

Main Results:

  • Divergent assessment methods result in varied descriptions of IN shapes.
  • Medial and lateral wall ridges offer arthroscopic orientation; osteochondral ridges may increase ligament injury risk.
  • Age and sex-related changes in the IN underscore the need for personalized knee evaluations.

Conclusions:

  • Accurate knowledge of intercondylar fossa morphology is vital for assessing ligament injury risk.
  • The interplay between the osseous housing and internal structures is critical for knee joint stability.
  • Individualized assessment of the knee joint is paramount due to anatomical variations and influencing factors.
