Bones of the Lower Limb: Femur and Patella

Bones 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...

Knee Joint

Knee 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...

Muscles that Move the Leg

Muscles 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...

Summary

Traumatic patellar dislocation in adolescents requires addressing loose bodies during acute treatment. Medial patellofemoral ligament reconstruction offers excellent outcomes for acute and recurrent cases.

Area of Science:

Orthopedic surgery
Sports medicine
Adolescent knee injuries

Background:

Traumatic patellar dislocation is a frequent injury among adolescents.
Current acute treatment strategies remain a subject of debate.
Osteochondral loose bodies are a common complication requiring management.

Observation:

The management of osteochondral loose bodies is a critical aspect of acute patellar dislocation treatment.
Surgical reconstruction of the medial patellofemoral ligament (MPFL) is considered for specific patient groups.
Excellent results have been reported with MPFL reconstruction in both acute and recurrent patellar dislocations.

Findings:

Addressing osteochondral loose bodies during the acute phase is essential.
Medial patellofemoral ligament reconstruction demonstrates high efficacy.
This surgical approach yields superior outcomes in a select adolescent population.

Implications:

Optimal management of acute traumatic patellar dislocations in adolescents involves addressing loose bodies.
Medial patellofemoral ligament reconstruction is a viable and effective treatment for recurrent patellar instability.
Further research may refine acute treatment protocols and indications for MPFL reconstruction.
