Summary
Injuries to the knee posterolateral corner can cause instability and long-term disability. Advanced studies show improved reconstruction techniques offer better outcomes for stabilizing the knee.
Area of Science:
- Orthopedic surgery
- Knee biomechanics
- Sports medicine
Background:
- The posterolateral knee region is critical for knee joint stability, particularly at low flexion angles.
- Posterolateral corner injuries can lead to varus angulation, external rotation, and posterior translation, potentially causing chondral degeneration.
- Untreated posterolateral corner injuries may compromise cruciate ligament reconstruction outcomes.
Purpose of the Study:
- To review the anatomy and function of the posterolateral knee structures.
- To highlight the role of the posterolateral corner in knee stabilization and kinematics.
- To discuss current and emerging methods for posterolateral knee reconstruction.
Main Methods:
- Review of advanced biomechanical studies and sectioning/loading experiments.
- Analysis of anatomical structures and their role in knee kinematics.
- Evaluation of various surgical repair and reconstruction techniques.
Main Results:
- The posterolateral corner is essential for preventing varus, external rotation, and posterior translation.
- Injuries in this region can result in increased articular pressure and chondral damage.
- Newer reconstruction methods demonstrate promising superior outcomes.
Conclusions:
- Accurate diagnosis and treatment of posterolateral corner injuries are vital for successful knee stabilization.
- Advanced understanding and surgical techniques are improving outcomes for posterolateral knee reconstruction.
- Addressing posterolateral corner injuries is crucial for preventing long-term knee dysfunction.

01:16Bones of the Lower Limb: Femur and Patella
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 neck...
01:23Knee 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 group...

01:23Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
