Summary
Congenital dislocation of the knee (CDK) is a rare condition diagnosed clinically or via imaging. Early intervention, conservative or surgical, offers a good prognosis, especially for idiopathic cases.
Area of Science:
- Orthopedics
- Pediatric Surgery
- Medical Genetics
Context:
- Congenital dislocation of the knee (CDK) is a rare congenital knee deformity.
- It can occur as an isolated condition or be associated with various genetic syndromes.
- Clinical diagnosis relies on observing knee hyperextension at birth.
Purpose:
- To summarize the current understanding of congenital dislocation of the knee.
- To outline diagnostic methods and proposed pathogenetic mechanisms.
- To discuss therapeutic approaches and prognosis.
Summary:
- CDK presents as knee hyperextension, diagnosed clinically and confirmed by imaging (X-ray, sonography).
- The leading theory suggests quadriceps fibrosis and contracture as the primary cause.
- Treatment involves early conservative (casting) or operative interventions, tailored to syndromic or isolated cases.
Impact:
- Highlights the importance of early diagnosis and intervention for congenital knee dislocation.
- Emphasizes the generally favorable prognosis for idiopathic CDK with appropriate management.
- Provides a concise overview for clinicians managing this rare pediatric orthopedic condition.

02:15M-Cdk Drives Transition Into Mitosis
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

02:34Inhibition of Cdk Activity
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
00:50Anaphase Promoting Complex
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...
01:23Knee Joint
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 group...

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