The typical signs of a torn patellar tendon include:
The patellar tendon is supplied by the following arteries and their anastomoses 3:
Causes. Patellar tendinitis is a common overuse injury, caused by repeated stress on your patellar tendon. The stress results in tiny tears in the tendon, which your body attempts to repair. But as the tears in the tendon multiply, they cause pain from inflammation and weakening of the tendon.
When the patellar tendon is completely torn, the tendon is separated from the kneecap. Without this attachment, you cannot straighten your knee. The patellar tendon often tears at the place where it attaches to the kneecap, and a piece of bone can break off along with the tendon.
The patellar tendon is the distal portion of the common tendon of the quadriceps femoris, which is continued from the patella to the tibial tuberosity. It is also sometimes called the patellar ligament as it forms a bone to bone connection when the patella is fully ossified.
This type of injury requires prompt diagnosis and surgical repair as the patellar tendon is a part of the extensor mechanism. The extensor mechanism of the knee is crucial to the function of the lower extremity, including ambulation.

The quadriceps tendon attaches the quadriceps muscles to the knee cap (“patella”). The patellar tendon attaches the knee cap to the shin bone. These muscles, tendons and bones work together to straighten the knee. Although patellar and quadriceps tendon ruptures or tears are rare, they are serious injuries.
The patellar tendon connects the bottom of the kneecap (patella) to the top of the shinbone (tibia). Despite its name, the patellar tendon is actually a ligament. Tendons connect a muscle to a bone.
Overall, patellar tendon rupture is the third most common injury to the extensor mechanism of the knee, following patellar fracture and quadriceps tendon rupture.
A tendon is connective tissue that connects a muscle to a bone. From the perspective of muscle action, the term patellar tendon is correct. Another perspective to consider is that because the patellar 'tendon' connects a bone to a bone (patella to tibial tuberosity), it could be referred to as the patellar ligament.
tibial tuberosityThe patellar tendon originates from the anterior aspect of the distal end of the patella, coursing anterior to the knee joint, and inserts on the tibial tuberosity.
A small, partial patellar tendon tear may be adequately treated with nonsurgical treatments such as immobilization, assistive braces, and physical therapy. However, a complete patellar tendon rupture will require surgery, as will a partial patellar tendon injury that has not responded adequately to nonsurgical methods.
The patella is also known as the kneecap. It sits in front of the knee joint and protects the joint from damage. It is the largest sesamoid bone in the body, and lies within the quadriceps tendon....Patella.TypeSesamoid bonePartsApex (pointing inferiorly), medial and lateral borders, base (lies proximally)3 more rows
