patellaarijänteeseen

Patellaarijänteeseen, often referred to as the patellar tendon, is a strong band of fibrous tissue that connects the patella, or kneecap, to the tibia, the shinbone. This crucial ligament plays a vital role in the extension of the knee. When the quadriceps muscles contract, they pull on the patella, and the patellar tendon transmits this force to the tibia, allowing the leg to straighten.

The patellar tendon is a continuation of the quadriceps tendon, which attaches to the superior pole of the patella. The patellar tendon itself attaches to the inferior pole of the patella and extends down to the tibial tuberosity, a bony prominence on the front of the tibia. Its smooth, cord-like structure allows for efficient transmission of force.

Injuries to the patellar tendon can range from tendinitis, an inflammation caused by overuse, to more severe tears. Patellar tendinitis, commonly known as "jumper's knee," often affects athletes involved in sports that require repetitive jumping and landing. Symptoms can include pain, tenderness, and swelling in the front of the knee, particularly below the kneecap. Complete tears of the patellar tendon are less common but are serious injuries that typically require surgical intervention to repair. These tears can occur due to sudden forceful contraction of the quadriceps or direct trauma to the knee.
