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.
Patellofemoral pain syndrome can become a chronic injury, with an estimated 50% of people reporting persistent patellar-femoral pain after a year. [32] Risk factors for a prolonged recovery (or persistent condition) include age (older athletes), females, increased body weight, a reduction in muscle strength, time to seek care, and in those who ...
All four parts of the quadriceps muscle attach to the shin via the patella (knee cap), where the quadriceps tendon becomes the patellar ligament. It attaches the quadriceps to the top of the patella, which in turn is connected to the shin from its bottom by the patellar ligament. A tendon connects muscle to bone, while a ligament connects bone ...
All four parts of the quadriceps muscle attach to the patella (knee cap) by the quadriceps tendon. The rectus femoris is situated in the middle of the front of the thigh ; it is fusiform in shape, and its superficial fibers are arranged in a bipenniform manner, the deep fibers running straight ( Latin : rectus ) down to the deep aponeurosis .
The patella is attached to the tendon of the quadriceps femoris muscle, which contracts to extend/straighten the knee. The patella is stabilized by the insertion of the horizontal fibres of vastus medialis and by the prominence of the lateral femoral condyle, which discourages lateral dislocation during flexion. The retinacular fibres of the ...
The bones of the knee are the femur, patella, tibia, and fibula. The fibula is on the lateral side of the knee and the patella has little effect on the medial side of the knee. The bony congruity of the medial knee consists of the opposing surfaces of the medial femoral condyle and the medial tibial plateau.
The suprapatellar bursa is prevented from being pinched during extension by the articularis genus muscle. [4] On the tibia, the anterior reflection and attachment of the synovial membrane is located near the cartilage. [2] Anteriorly, the infrapatellar fat pad is inserted below the patella and between the two membranes.
The quadriceps muscles consist of the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These quadriceps muscles are innervated by the femoral nerve. [ 1 ] The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when ...
