Summary
The pivot shift test is the most sensitive clinical evaluation for anterior cruciate ligament (ACL) insufficiency. This review covers the history, biomechanics, and treatment of the pivot shift phenomenon in ACL-deficient knees.
Area of Science:
- Orthopedics
- Sports Medicine
- Biomechanics
Background:
- The anterior cruciate ligament (ACL) is crucial for knee stability.
- ACL insufficiency leads to abnormal joint motion and symptoms during flexion-extension.
- Clinical tests like Lachman and anterior drawer assess ACL integrity, but the pivot shift test uniquely simulates the injury mechanism.
Conclusions:
- The pivot shift test is a cornerstone in diagnosing ACL insufficiency due to its sensitivity and ability to simulate the injury.
- Understanding the biomechanics of the pivot shift is essential for effective management of ACL tears.
- Further research and consistent application of the pivot shift test can improve patient outcomes in ACL-deficient knees.

01:23Knee Joint
2.0K
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...

01:16Bones of the Lower Limb: Femur and Patella
2.6K
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...

01:23Muscles that Move the Leg
2.1K
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...

01:10Ankle Joint
1.6K
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...

01:16Eccentric Axial Loading in a Plane of Symmetry

Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

01:16Thermal Sigmatropic Reactions: Overview
2.1K
Sigmatropic rearrangements are a class of pericyclic reactions in which a σ bond migrates from one part of a π system to another. These are intramolecular rearrangements where the total number of σ and π bonds remain unchanged.
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in...
