Apex of patella

Apex of patella is the pointed, inferior part of the patella, or kneecap, which is a small bone located in front of the knee joint. The apex is the lowest point of the patella and is the attachment site for the patellar ligament, which connects the patella to the tibia.

Anatomy

The patella is a triangular bone with the apex pointing downwards. The apex of the patella is the tip of this triangle and is located at the lower end of the bone. It is the point from which the patellar ligament originates. This ligament is a continuation of the quadriceps tendon, which attaches to the top of the patella.

The apex of the patella is an important anatomical landmark as it is used in medical examinations to assess the health of the knee joint. It is also used as a reference point in surgical procedures involving the knee.

Function

The primary function of the apex of the patella is to serve as the attachment site for the patellar ligament. This ligament plays a crucial role in the knee joint as it provides stability and allows for movements such as knee extension.

The apex of the patella, along with the rest of the patella, also serves to protect the knee joint from physical impact and injury.

Clinical significance

Injuries or conditions affecting the apex of the patella can lead to pain and reduced mobility. These include patellar tendinitis, also known as jumper's knee, which is inflammation of the patellar ligament that can result from overuse or injury.

Patellar fractures can also involve the apex of the patella. These fractures are often caused by direct trauma to the knee, such as a fall or blow to the knee. Treatment may involve surgery to repair the fracture and restore function to the knee.
