Patella Fracture

Understanding Patella Fractures: Causes, Symptoms, and Treatment

The patella, or kneecap, is a crucial component of the knee joint. It safeguards the joint while enabling attachment for various thigh and leg muscles. Covered with articular cartilage, the patella facilitates smooth knee joint movement. While patella fractures are rare, they are more common among adult males.

Causes of Patella Fracture

Fractures typically result from direct impact to the kneecap, such as falls or motor vehicle accidents. Indirect fractures may occur due to sudden thigh muscle contractions.


Symptoms of a patella fracture include pain, swelling, difficulty walking, and knee straightening challenges. Bruising around the fracture site may also be observed.


To diagnose patella fractures, a thorough physical examination, injury history review, and X-ray imaging are employed. X-rays are particularly effective in identifying the nature and severity of the fracture.


Treatment approaches vary based on the fracture’s severity:

  • Non-surgical Treatment: For non-fragmented or non-displaced fractures, immobilization with casts or splints aids in healing. Limb immobilization for 6 to 8 weeks may be recommended.
  • Surgical Treatment: Surgery is recommended for displaced fractures or when fragments are too far apart for effective healing. Immediate surgery is crucial for open fractures. The surgical method depends on the fracture type; transverse fractures are stabilized with wires and pins, while comminuted fractures may require removal of smaller bone fragments.


Rehabilitation is essential for restoring mobility and strength post-fracture treatment. Physical therapy, joint mobilization, muscle-strengthening exercises, and weight-bearing activities help regain strength and prevent deformities.

By understanding the causes, symptoms, and treatment options for patella fractures, individuals can actively engage in their recovery journey, facilitating optimal healing and restoring normal knee function.
