Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

8.9K
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...

Knee Joint01:23

Knee Joint

3.5K
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...

Muscles that Move the Leg01:23

Muscles that Move the Leg

5.7K
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...

Area of Science:

  • Orthopedic surgery
  • Biomechanics
  • Knee anatomy

Background:

  • Rotatory instability is a significant concern in knee injuries.
  • Anterolateral soft-tissue structures play a key role in knee stability.
  • The specific contributions of these structures require detailed investigation.

Purpose of the Study:

  • To review evidence on anterolateral soft-tissue structures and knee rotatory stability.
  • To determine the primary structure responsible for resisting anterolateral rotatory instability.
  • To elucidate the biomechanical role of the ilio-tibial band.

Main Methods:

  • Review of existing scientific literature on knee biomechanics.
  • Analysis of structural properties and isometry of anterolateral knee structures.
  • Biomechanical demonstration of stability contributions.

Main Results:

  • The ilio-tibial band exhibits critical structural properties and isometry for knee stability.
  • Evidence supports the ilio-tibial band's significant role in resisting tibial internal rotation.
  • Biomechanical data confirm the ilio-tibial band as the key restraint against anterolateral rotatory instability.

Conclusions:

  • The ilio-tibial band is the most important structure for maintaining anterolateral rotatory stability of the knee.
  • Understanding the ilio-tibial band's function is vital for managing knee instability.
  • Further research can refine surgical and rehabilitation strategies for knee injuries.
