Knee Joint

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...

Area of Science:

Orthopedic Surgery
Emergency Medicine
Trauma Care

Background:

Knee dislocations carry severe risks, including arterial, venous, and neurologic compromise.
These injuries are limb-threatening and demand urgent medical attention.

Purpose of the Study:

To emphasize the critical importance of expedient diagnosis and management of knee dislocations.
To highlight key steps in the initial assessment and treatment of this injury.

Main Methods:

Clinical assessment of physical findings.
Rapid evaluation of neurovascular status.
Immediate splinting and emergency department transport.

Main Results:

Expedient diagnosis and management are essential to mitigate limb-threatening complications.
Spontaneous reduction can complicate diagnosis, requiring a high index of suspicion for globally unstable knees.

Conclusions:

Physicians must suspect knee dislocation in cases of global knee instability.
Timely diagnosis, neurovascular assessment, and emergency transport are paramount for managing knee dislocations.
