The patella rests in the trochlear, which is found in the distal part of the femur. The patella can dislocate from the groove because of trauma or an unnatural twisting of the knee. [5] When dislocated, the soft tissue layer that the patella rests in is damaged; the patella is forced out of its groove and back into place.
To assess the knee, a clinician can perform the Patellar Aprehension Test by moving the patella back and forth while the people flexes the knee at approximately 30 degrees. [ 14 ] The people can do the patella tracking assessment by making a single leg squat and standing, or by lying on his or her back with knee extended from flexed position.
Anteriorly, the infrapatellar fat pad is inserted below the patella and between the two membranes. It extends from the lower margin of the patella above, to the infrapatellar synovial fold below. With its free upper margin, this fold extends dorsally through the joint space to surround the two cruciate ligaments from the front, thus dividing ...
The patellar network (circulatory anastomosis around the knee-joint, patellar anastomosis, genicular anastomosis, articular vascular network of knee [1] or rete articulare genus [2]) is an intricate network of blood vessels around and above the patella, and on the contiguous ends of the femur and tibia, forming a superficial and a deep plexus.
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 the tendon of the quadriceps femoris.
A luxating patella, sometimes called a trick knee, is a condition in which the patella, or kneecap, dislocates or moves out of its normal location. It can be associated with damage to the anterior cruciate ligament .
The infrapatellar fat pad (Hoffa's fat pad) is a cylindrical piece of fat that is situated inferior and posterior to the patella bone within the knee, [1] intervening between the patellar ligament and synovial fold of the knee joint.
The most well-known sesamoid bone is the patella, more commonly known as the "knee cap". It is located cranially to the joint and sits in the trochlear groove of the femur. It guides the patellar ligament of the quadriceps over the knee joint to its point of insertion on the tibia.
