The proximal end features the femoral head, a spherical structure that fits into the acetabulum of the pelvis to create the hip joint. When this tracking is disrupted, it can lead to conditions such as patellar tendinitis or chondromalacia patellae, commonly known as runner's knee.
Patellar Mechanics Tracking: How the Kneecap Moves and Supports Upper Leg Bones
Its primary role is to protect the knee joint and to increase the leverage of the quadriceps tendon, effectively acting as a natural pulley. This sesamoid bone is embedded within the tendon of the quadriceps femoris muscle.
By altering the angle of tendon pull, the patella allows for more efficient extension of the leg at the knee, which is essential for activities such as running, jumping, and rising from a seated position. Maintaining strong quadriceps and hip stabilizer muscles is key to ensuring the patella moves smoothly and securely during dynamic movements.

Distal femur fractures often occur due to high-impact trauma and can involve the complex joint surface of the knee. Femoral neck fractures are a serious concern, particularly in elderly individuals with osteoporosis, as they can severely limit mobility and require surgical intervention.
