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...

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...

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...

Ankle Joint

Ankle Joint

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...

Background:

Patella dislocation is a frequent knee injury, representing 3% of acute cases.
Diagnosis can be challenging, with hemarthrosis being a non-specific indicator.
Thorough patient history and physical examination are essential for identification.

Purpose of the Study:

To highlight the importance of accurate diagnosis of patella dislocation.
To outline appropriate diagnostic and management strategies.
To emphasize the role of imaging in evaluating osseous and soft tissue structures.

Main Methods:

Review of clinical presentation and diagnostic challenges.
Emphasis on comprehensive history and physical examination.
Importance of cross-sectional imaging (e.g., MRI, CT) for detailed assessment.

Main Results:

Patella dislocation is often underdiagnosed.
Hemarthrosis is an unreliable sign.
Imaging is vital for identifying associated injuries and guiding treatment.

Conclusions:

Accurate and timely diagnosis of patella dislocation is critical.
Non-operative management is typical for acute cases.
Surgical intervention is indicated for structural damage, osteochondral defects, or recurrent dislocations, addressing underlying causes.
