Knee Joint01:23

Knee Joint

3.7K
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...

Bones of the Lower Limb: Femur and Patella

9.2K
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...

Summary

Long-term follow-up of traumatic knee dislocations shows that adhering to fundamental management principles can lead to excellent functional outcomes, even with radiographic signs of arthritis. This highlights the potential for high-level activity post-injury.

Area of Science:

  • Orthopedic Surgery
  • Trauma Management
  • Sports Medicine

Background:

  • Traumatic knee dislocation is increasingly recognized, often resulting from high-energy trauma.
  • Long-term outcomes and management principles for knee dislocations require further elucidation.

Observation:

  • Two cases of multiligamentous knee reconstruction after traumatic dislocation were evaluated with a minimum 20-year follow-up.
  • Comprehensive subjective (Lysholm, Tegner, VAS, SF-36, IKDC, psychosocial) and objective (ligamentous exam, radiographs, functional assessment) measures were employed.

Findings:

  • Patients demonstrated excellent stability and high functional levels (e.g., hiking, skydiving) at an average of 22-year follow-up.
  • Despite radiographic evidence of arthritis, subjective scores indicated good to excellent outcomes (e.g., Lysholm 92, IKDC 86.5).
  • One patient required vascular repair prior to ligament reconstruction.

Implications:

  • Adherence to fundamental management principles in traumatic knee dislocations can yield rare, long-term excellent results.
  • Advances in evaluation and treatment are crucial for improving future long-term outcomes.
  • Patients can achieve high functional levels post-dislocation with appropriate care.
