|October 12, 2014
Summary
Adults with neglected developmental dysplasia of the hip (DDH) often show radiographic knee changes. These alterations in both affected and unaffected knees highlight the importance of considering knee morphology in surgical planning.
Area of Science:
- Orthopedics
- Radiology
- Biomedical Engineering
Background:
- Limited research exists on knee joint alterations in neglected developmental dysplasia of the hip (DDH).
- Understanding these changes is crucial for comprehensive patient management.
Purpose of the Study:
- To evaluate the radiographic morphology of knee joints in adult patients with neglected DDH.
Main Methods:
- Prospective study of 37 adults with neglected DDH and 37 healthy controls.
- Radiographic parameters of affected, unaffected, and control knees were measured in coronal and sagittal planes.
Main Results:
- Affected knees exhibited increased valgus angulation and decreased posterior angles in the distal femur and proximal tibia.
- Radiographic changes were also observed in unaffected knees compared to controls.
Conclusions:
- Neglected DDH is associated with significant radiographic changes in both ipsilateral and contralateral knee joints.
- These findings necessitate consideration of knee joint morphology during hip, femur, and knee surgeries to mitigate complications.

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...

01:16Bones of the Lower Limb: Femur and Patella
8.0K
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...

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...

01:07Development of the Limb Synovial Joints
4.9K
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.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:23Muscles that Move the Leg
6.7K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
