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...

Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

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...

Summary

Ultrasonography (USG) effectively diagnoses injuries associated with Traumatic Patellar Dislocation (TPD), including osteochondral fractures and medial patellar retinaculum damage. This imaging technique aids in determining appropriate treatment strategies for knee injuries.

Background:

Traumatic Patellar Dislocation (TPD) can cause significant knee injuries, including osteochondral fractures and damage to the medial patellar retinaculum.
Accurate diagnosis of these injuries is critical for effective treatment planning.

Purpose of the Study:

To evaluate the diagnostic utility of ultrasonography (USG) in identifying injuries associated with Traumatic Patellar Dislocation (TPD).
To assess the effectiveness of USG in visualizing osteochondral fractures and medial patellar retinaculum injuries.

Main Methods:

Analysis of USG patterns in 22 knees following TPD in 21 patients.
Standard knee USG supplemented by patellar articular cartilage assessment and dynamic examination of the Medial Patello-Femoral Ligament (MPFL).
Comparison of USG findings with clinical examination, X-ray imaging, and surgical outcomes.

Main Results:

USG identified various TPD-related injuries, including MPFL avulsion fractures (16), MPFL fiber injuries (17), osteochondral fractures (12), and cartilage injuries (8).
Sonographic diagnoses were confirmed in 91% of cases (20 out of 22 knees).
High accuracy was noted in surgically treated patients (13 out of 15).

Conclusions:

Ultrasonography is a valuable tool for diagnosing knee extensor apparatus and articular cartilage injuries resulting from TPD.
Dynamic USG assessment allows for examination of patellar articular cartilage and MPFL function.
USG aids in establishing appropriate treatment strategies for traumatic patellar dislocations.
