Knee Joint01:23

Knee Joint

3.5K
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...

Bones of the Lower Limb: Femur and Patella

8.9K
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...

Area of Science:

  • Orthopedic Surgery
  • Trauma Management

Background:

  • Complex knee trauma includes juxta- and intraarticular fractures (floating knee), intraarticular fractures with severe soft tissue damage, and knee dislocations with vascular or soft tissue lesions.
  • These injuries necessitate a specialized management protocol due to their severity and potential for complications.

Purpose of the Study:

  • To outline a specific management protocol for complex knee trauma.
  • To emphasize the importance of minimally invasive techniques and appropriate ligamentous reconstruction.

Main Methods:

  • Soft-tissue sparing, minimally invasive reduction and fixation techniques for fractures, including percutaneous plate fixation, percutaneous screw osteosynthesis, and hybrid fixation.
  • Reconstruction of the central pivot (cruciate ligaments) in knee dislocations using augmented repair or primary tendon grafting.
  • Treatment of collateral ligament lesions based on specific injury type.

Main Results:

  • Minimally invasive techniques are crucial for reducing the complication rate in complex knee fractures.
  • Consistent reconstruction of the central pivot is essential for knee dislocations.
  • Tailored treatment for collateral ligament injuries is necessary.

Conclusions:

  • A specific protocol involving minimally invasive fracture fixation and comprehensive ligamentous reconstruction is vital for managing complex knee trauma.
  • Adherence to these principles can significantly decrease complication rates and improve patient outcomes.
