The patella, commonly referred to as the kneecap, is an example of a sesamoid bone. Sesamoid bones function to protect tendons from stress and wear. These small, round bones are commonly found in the tendons of the hands, knees, and feet. Sesamoid bones are bones embedded in tendons. It protects the knee and connects the muscles in the front of the thigh to the tibia. The patella is a small bone located in front of the knee joint - where the thighbone (femur) and shinbone (tibia) meet. The patellar tendon is biconvex and, similarly to the calcaneal tendon, does not have a tendon sheath but only a paratenon composed of loose areolar tissue. The extensor mechanism of the knee is crucial to the function of the lower extremity, including ambulation. This type of injury requires prompt diagnosis and surgical repair as the patellar tendon is a part of the extensor mechanism.
The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface below, it inserts on the tuberosity of the tibia its superficial fibers are continuous over the front of the patella with those of … Is the patellar tendon a flexor or extensor? What type of tendon is the patellar tendon? The patella is the largest sesamoid bone in the human body and is located anterior to knee joint within the tendon of the quadriceps femoris muscle, providing an attachment point for both the quadriceps tendon and the patellar ligament.
