On December 19, 2007, during the first quarter of the game versus the Atlanta Hawks while getting back on a fast-break, Alonzo Mourning tore the patellar tendon in his right knee and was required to undergo season-ending knee surgery.

Two non-communicative bursae are located in front of the patella and below the patellar tendon, and others are sometimes present.

It is also occasionally called the patellar tendon because there is no definite separation between the quadriceps tendon ( which surrounds the patella ) and the area connecting the patella to the tibia.

Generally tendinitis is referred to by the body part involved, such as Achilles tendinitis ( affecting the Achilles tendon ), or patellar tendinitis ( jumper's knee, affecting the patellar tendon ).

The tuberosity of the tibia, a crest to which the patellar ligament attaches in mammals, is instead the insertion point for the tendon of the quadriceps muscle in reptiles, birds, and amphibians, which have no patella.

The deep tendon reflexes are also diminished or absent ; for example, the " knee jerk " or patellar reflex may be lacking ( Westphal's sign ).

Dr. Neal ElAttrache performed the anterior cruciate ligament reconstruction at the Los Angeles Kerlan-Jobe Orthopaedic Clinic October 6, using Brady's patellar tendon graft to replace the torn ligament, and also repaired his medial collateral ligament, through a separate incision in his left knee.

Some reflex responses, such as withdrawing the hand after touching a hot surface, are protective, but others, such as the patellar reflex " knee jerk " activated by tapping the patellar tendon, contribute to ordinary behavior.

The " patellar tendon " that connects the kneecap to the tibia ( shinbone ) is elongated ( longer than normal ).

It is the ratio of the length of the patella to the length of the patellar tendon.

When the patellar tendon is tapped just below the knee, the patellar reflex is initiated and the lower leg kicks forward ( via contraction of the quadriceps ).

This is via the patella, where the quadriceps tendon becomes the patellar ligament, which then attaches to the tibia.

The patellar reflex or knee-jerk is a deep tendon reflex and is a myotatic reflex.

Striking the patellar tendon with a tendon hammer just below the patella stretches the muscle spindle in the quadriceps femoris muscle.

Sinding – Larsen – Johansson syndrome, named after Sven Christian Johansson ( 1880-1959 ), a Swedish Surgeon and Christian Magnus Falsen Sindig-Larsen ( 1866-1930 ), a Norwegian Physician, is an analogous condition involving the patellar tendon and the lower margin of the patella bone, instead of the upper margin of the tibia.

The condition is usually self-limiting and is caused by stress on the patellar tendon that attaches the quadriceps muscle at the front of the thigh to the tibial tuberosity.

Following an adolescent growth spurt, repeated stress from contraction of the quadriceps is transmitted through the patellar tendon to the immature tibial tuberosity.

The tendon below the patient's knee is then hit with a reflex hammer to elicit the patellar reflex.

The patellar ligament connects the patella to the tuberosity of the tibia.

It occurs when, through either malformation or trauma, the ridges forming the patellar groove in the knee are not prominent and are too shallow to allow the patella to properly sit securely.

The knee is a hinge type synovial joint, which is composed of three functional compartments: the femoropatellar articulation consists of the patella, or " kneecap ", and the patellar groove on the front of the femur through which it slides ; and the medial and lateral femorotibial articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower leg.

It begins as inflammation in the patellar tendon where it attaches to the patella and may progress by tearing or degenerating the tendon.

In addition to back problems, the breed is also prone to patellar luxation which is where the kneecap can become dislodged.

Laterally and medially to the patellar ligament the lateral and medial patellar retinacula connect fibers from the vasti lateralis and medialis muscles to the tibia.

Despite missing 15 games with chicken pox and patellar tendinitis in both knees that plagued him throughout the first half of the 1993 season, Anderson led all American League leadoff hitters in extra-base hits ( 56 ) and RBI ( 62 ).

On the tibial and patellar glands, relationships, and American genera of the spider family Leptonetidae ( Arachnida, Araneae ).

This happens through one of two actions ( or a mix of the two ): when the lower ribs the diaphragm connects to are stabilized by muscles and the central tendon is mobile, when the muscle contracts the central tendon is drawn down, compressing the cavity underneath and expanding the thoracic cavity downward.

A tendon ( or sinew ) is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension.

A tendinous band, called the tendon of the conus arteriosus, extends upward from the right atrioventricular fibrous ring and connects the posterior surface of the conus arteriosus to the aorta.

A tendon is a tough, flexible band of fibrous connective tissue that connects muscles to bones.

In conjunction with the coracoid and the scapula, it forms a unique structure called the triosseal canal, which houses a strong tendon that connects the supracoracoideus muscles to the humerus.

For didactic reasons, the ' tendon ' of the gallbladder meridian is chosen: this meridian tendon runs down the outside of the body and connects the temples with the outer area of the foot.

Tape from the bottom half of the patella, to under the knee over the patella tendon.

In this process, osteocytes inflitrate the tendon and lay down bone as they would in sesamoid bone such as the patella.

* In the knee — the patella ( within the quadriceps tendon ).

The muscle may be split into two parts, and one part may be inserted into the fascia lata, the femur, the ligament of the patella or the tendon of the Semitendinosus.

The surgery required is governed by the type of abnormality present, but often involves a sulcoplasty, a deepening of the trochlear sulcus that the patella sits in, a re-alignment of the attachment of the patella tendon on the tibia, and tightening / releasing of the capsule either side of the patella, according to which side the patella is slipping.

The term knee-jerk was recorded by Sir Michael Foster in his Textbook of physiology in 1877: " Striking the tendon below the patella gives rise to a sudden extension of the leg, known as the knee-jerk.

With Klecko rupturing the patella tendon in his right knee in the second game of the strike shortened 1982 season against the New England Patriots, Gastineau became the new unofficial leader of the " Sack Exchange.

Washington finally tore the patella tendon in a late season game against Denver.

Klecko appeared in only one regular season game for the Jets in 1982, rupturing the patella tendon in his right knee in the second game of the season against the New England Patriots.

His successful season came at a price as, after ignoring doctor's orders, the tendinitis in his patella worsened and an Achilles tendon injury doubled his health difficulties.
