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...

Background:

Bilateral patellar tendon rupture is uncommon, often linked to systemic conditions or tendinopathy.
Risk factors include chronic overuse, steroid use, and certain metabolic diseases.

Observation:

A 34-year-old male, a retired basketball player with a history of steroid use, presented with simultaneous bilateral patellar tendon rupture after minor trauma.
The patient had no prior history of chronic knee pain or knee-related issues.

Findings:

Surgical management involved primary end-to-end tendon repair, temporarily stabilized with cerclage wiring.
Post-operative care included brief immobilization and a comprehensive rehabilitation program.

Implications:

This case highlights successful surgical outcomes for bilateral patellar tendon ruptures, even in the absence of predisposing factors.
Early and intensive rehabilitation is crucial for restoring function and enabling a return to high-demand activities in athletes.
