Knee Joint

2.7K
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...

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Summary
This summary is machine-generated.

Unclassifiable floating knee injuries show poorer clinical outcomes compared to classified ones. This suggests a need for a new classification system to better manage these complex fractures.

Area of Science:

  • Orthopedic Surgery
  • Trauma Management
  • Clinical Outcomes Research

Background:

  • Floating knee injuries present complex challenges in classification and treatment.
  • Existing classification systems may not adequately encompass all variations of floating knee injuries.
  • Evaluating outcomes based on current classifications is crucial for identifying treatment gaps.

Purpose of the Study:

  • To compare clinical and radiological outcomes of floating knee injuries based on the Karlstrom-Olerud Scoring System.
  • To assess the adequacy of current classifications (Fraser, Blake, McBryde) for floating knee injuries.
  • To determine if a new classification system is necessary for floating knee injuries.

Main Methods:

  • Retrospective analysis of 70 floating knee injury patients treated between 2008 and 2019.
  • Statistical comparison of outcomes for classifiable versus unclassifiable fractures using Fraser, Blake, and McBryde systems.
  • Evaluation based on the Karlstrom-Olerud criteria.

Main Results:

  • Fractures unclassifiable by Blake and McBryde showed statistically poorer outcomes (p=0.041).
  • Fractures unclassifiable by Fraser also demonstrated statistically poorer outcomes compared to classifiable ones (p=0.010).
  • A significant difference in clinical results was observed between classified and unclassified floating knee injuries.

Conclusions:

  • Floating knee injuries that cannot be classified using existing systems yield poorer clinical results.
  • There is a clear need for a new, comprehensive classification system for floating knee injuries.
  • A revised classification should incorporate segmental, patellar, and open fractures for improved management.
