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
Biomechanics

Background:

Instability is a frequent cause of total knee arthroplasty failure.
Surgical errors and improper implant selection are contributing factors.
Accurate diagnosis relies heavily on patient history and physical examination.

Purpose of the Study:

To review and detail the three primary patterns of tibiofemoral instability.
To provide a deeper understanding of flexion instability, genu recurvatum, and extension instability.

Main Methods:

Literature review of tibiofemoral instability patterns.
Clinical assessment and diagnostic criteria for instability.

Main Results:

Tibiofemoral instability can be categorized into three distinct patterns.
Detailed review of flexion instability, genu recurvatum, and extension instability.

Conclusions:

Understanding these instability patterns is crucial for accurate diagnosis.
Proper diagnosis is fundamental for successful total knee arthroplasty outcomes.
