The four most common causes of patellar fractures

The patella is a bone in the human knee. If it has fracture symptoms, it will also affect people's normal walking ability. So, what are the causes of patella fracture?

1. External injuries

Fractures occur in the area where external force is directly applied, such as blows and collisions. They are mostly comminuted or transverse fractures. The soft tissue damage varies in severity and is mostly open, which is one of the causes of fractures.

2. Indirect violence

Indirect violence can also easily lead to fractures. The fracture is far from the point of contact of the external force. Most of them are closed fractures with less damage to soft tissue.

3. Strong muscle contraction

Patellar fractures are often caused by sudden obstruction during strong muscle contraction, which leads to damage to the bone tissue and causes patellar fractures.

4. Fatigue fracture

Long-term repeated direct or indirect external force, concentrated at a certain point of the bone path, causes fractures, such as fractures of the second and third tendons, which is also one of the causes of fractures.
