Knee Joint01:23

Knee Joint

3.8K
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...

Ankle Joint01:10

Ankle Joint

3.8K
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...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.8K
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...

Muscles that Move the Leg01:23

Muscles that Move the Leg

6.9K
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
  • Sports Medicine
  • Knee Biomechanics

Background:

  • Multiligament knee injuries (MLKIs) represent severe trauma with complex diagnostic and management challenges.
  • Current approaches struggle with classification, treatment, and rehabilitation of these injuries.
  • A comprehensive understanding of MLKIs is crucial for optimal patient outcomes.

Purpose of the Study:

  • To review current evidence and expert opinions on evaluating and managing MLKIs.
  • To outline key principles for diagnosis, surgical planning, and rehabilitation.
  • To provide guidance on contemporary reconstruction strategies for MLKIs.

Main Methods:

  • Synthesis of current scientific evidence.
  • Inclusion of expert clinical perspectives.
  • Review of diagnostic modalities and surgical techniques.

Main Results:

  • Clinical examination, stress radiography, and MRI enhance injury characterization and laxity quantification.
  • Associated injuries (posteromedial/posterolateral corner, meniscal) require careful management to protect grafts.
  • Evidence supports early, single-stage surgery in selected MLKI patients.
  • Restoration of anatomy, biomechanical stability, and meticulous surgical planning are vital.

Conclusions:

  • Modern MLKI management necessitates a thorough, integrated approach.
  • Early surgical intervention, when appropriate, can improve outcomes.
  • Attention to associated pathologies and rehabilitation is critical for successful reconstruction.
