Patellar ligament

Patellar Ligament

The Patellar Ligament is a key component of the human anatomy, specifically within the knee joint. It is a strong, flat, ligamentous structure that connects the patella (kneecap) to the tibia (shinbone).

Anatomy

The patellar ligament originates from the lower tip of the patella and extends downwards to insert into the tibial tuberosity. It is the central part of the quadriceps tendon, which is the common tendon of the four-headed quadriceps femoris muscle. The ligament is approximately 2 inches long and is the continuation of the quadriceps tendon.

Function

The primary function of the patellar ligament is to aid in knee extension. It works in conjunction with the quadriceps femoris muscle to extend the knee and allow for movements such as walking, running, and jumping.

Clinical Significance

Injuries to the patellar ligament can result in conditions such as patellar tendinitis (also known as jumper's knee), which is inflammation of the ligament caused by overuse. In severe cases, the ligament can rupture, requiring surgical repair. The patellar ligament is also commonly used in anterior cruciate ligament (ACL) reconstruction surgery.
