Bones of the Lower Limb: Femur and Patella01:16

Bones 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...
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Knee Joint01:23

Knee 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...

Arthroscopic Excision of Posterior Cruciate Ligament Cysts Using a Double Posteromedial Approach

Published on: October 20, 2023

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomechanics

Background:

  • Displaced patella fractures commonly disrupt the knee's extensor mechanism, essential for unassisted gait.
  • Surgical intervention is typically recommended for displaced patella fractures to restore extensor mechanism integrity.

Purpose of the Study:

  • To review the operative management of displaced patella fractures.
  • To discuss fixation techniques and potential long-term outcomes.

Main Methods:

  • Review of standard surgical approaches for patella fracture fixation.
  • Discussion of fixation techniques including tension band wiring, interfragmentary screws, cerclage, and plate-and-screw constructs.
  • Consideration of partial patellectomy with tendon/ligament advancement.

Main Results:

  • Open reduction and internal fixation (ORIF) is the primary surgical approach.
  • Comminuted fractures may require supplemental fixation beyond traditional tension band wiring.
  • Patellofemoral joint arthrosis and persistent functional deficits are common sequelae.

Conclusions:

  • Effective surgical management of displaced patella fractures is crucial for restoring knee extensor function.
  • Advanced fixation techniques may be necessary for complex fractures.
  • Long-term outcomes frequently include patellofemoral arthrosis and functional limitations.
