Knee Joint01:23

Knee Joint

2.4K
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

3.5K
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
  • Radiology

Background:

  • Knee dislocation is a severe injury with potential for limb-threatening complications.
  • Three types of knee dislocation exist: patellofemoral, tibiofemoral, and tibiofibular.
  • Tibiofemoral dislocation carries the highest risk of neurovascular compromise.

Observation:

  • A 40-year-old female sustained simultaneous dislocation of all three knee articulations after a moped accident.
  • Diagnosis was confirmed via clinical examination, plain films, CT, and MRI.
  • Management involved surgical debridement, reduction, and stabilization.

Findings:

  • This is the first reported case of simultaneous dislocation of all three knee articulations (patellofemoral, tibiofemoral, and tibiofibular).
  • The patient's injury was successfully managed with surgical intervention.
  • Close monitoring is required post-operatively for outcomes.

Implications:

  • Simultaneous tri-articular knee dislocation is an extremely rare but severe traumatic event.
  • Early recognition and surgical management are critical for limb salvage and functional recovery.
  • Long-term monitoring is necessary due to the high prevalence of post-traumatic osteoarthritis following severe knee injuries.
