Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

3.7K
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...

Knee Joint01:23

Knee Joint

2.5K
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...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

303
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Muscles that Move the Leg01:23

Muscles that Move the Leg

3.4K
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...

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

66
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Summary
This summary is machine-generated.

Congenital dislocation of the patella is a rare, irreducible condition requiring surgery. Treatment is generally favorable, though persistent flexion contracture and redislocation can occur postoperatively.

Area of Science:

  • Orthopedics
  • Pediatric Orthopedics
  • Skeletal Dysplasias

Background:

  • Congenital dislocation of the patella is a rare condition.
  • Characterized by irreducible lateral patellar dislocation.
  • Associated with congenital syndromes, lacking a clear inheritance pattern.

Purpose of the Study:

  • To review the characteristics, surgical management, and outcomes of congenital dislocation of the patella.
  • To identify common complications and areas for future research.

Main Methods:

  • Surgical management involving lateral release, medial stabilization, quadriceps lengthening, and distal realignment.
  • Review of patient outcomes and complication rates.

Main Results:

  • Surgical treatment generally yields favorable results.
  • Persistent flexion contracture and redislocation are the most common complications.

Conclusions:

  • Surgical intervention is necessary for irreducible congenital patellar dislocation.
  • Further research is needed to optimize treatment timing and strategies.
