Summary
Pediatric patellofemoral instability (PFI) involves complex causes beyond knee anatomy. This review focuses on evaluating PFI in young patients, considering coronal and transverse plane deformities and bony procedures.
Area of Science:
- Orthopedics
- Pediatric Sports Medicine
- Biomechanics
Background:
- Patellofemoral instability (PFI) includes symptomatic instability, subluxations, and dislocations.
- Acute patellar dislocation incidence is estimated at 43 per 100,000 children under 16.
- The medial patellofemoral ligament (MPFL) complex is crucial for patellar stability.
Purpose of the Study:
- Review the evaluation of PFI in pediatric and adolescent patients.
- Focus on the role of coronal and transverse plane deformities in PFI.
- Provide a framework for incorporating bony procedures for PFI treatment.
Main Methods:
- Literature review of patellofemoral instability evaluation.
- Analysis of anatomic factors contributing to PFI.
- Discussion of surgical techniques for bony deformities.
Main Results:
- PFI etiology is multifactorial, involving patella alta, tibial tubercle-trochlear groove distance, genu valgum, and torsional deformities.
- Coronal and transverse plane deformities significantly contribute to PFI.
- Bony procedures can be integrated into treatment frameworks.
Conclusions:
- Comprehensive evaluation of pediatric PFI requires assessing multiple anatomic factors.
- Addressing coronal and transverse plane deformities is essential for managing PFI.
- Surgical management may involve bony procedures to correct underlying deformities.

Bones of the Lower Limb: Femur and Patella
4.1K
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 Joint
2.6K
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 Joint
2.1K
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...
