Summary
Femoral anteversion, a cause of knee instability, requires thorough assessment including physical exams and imaging. Surgical correction with derotational osteotomies can improve outcomes for patients with significant rotational malalignment.
Area of Science:
- Orthopedic surgery
- Biomechanical analysis
Background:
- Femoral anteversion is a key anatomical factor linked to patellofemoral instability.
- Accurate assessment is crucial for identifying its contribution to patient symptoms.
Purpose of the Study:
- To review the role of femoral anteversion in patellofemoral instability.
- To discuss the diagnostic process and treatment options for rotational malalignment.
Main Methods:
- Literature review of diagnostic methods and surgical interventions.
- Analysis of clinical outcomes associated with femoral derotation.
Main Results:
- Comprehensive evaluation involves clinical history, physical examination, and imaging.
- Derotational femoral osteotomies are effective in correcting malalignment and improving symptoms.
Conclusions:
- Femoral anteversion significantly impacts patellofemoral stability.
- Surgical correction, tailored to the deformity's location, can enhance patient outcomes.

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...
