What is patellar lateralization?

What is patellar lateralization?

Constitutionally, it can appear, that due to lacking muscular guidance or as a consequence of former kneecap injuries, the kneecap drifts outwardly from its slide bearing. This is called patellar lateralization (outward drifting of the kneecap) or patellar subluxation.

What does patellar apprehension mean?

Description. Patellar apprehension sign is a physical finding in which forced lateral displacement of the patella produces anxiety and resistance in patients with a history of lateral patellar instability.

What causes patellar lateral dislocation?

Patellar Dislocations. A patella dislocation occurs when the knee cap pops sideways out of its vertical groove at the knee joint. It’s usually caused by force, from a collision, a fall or a bad step.

What is patellar dysplasia?

Some people are born with a shallow trochlear groove (= trochlear dysplasia). Some people have an L-shaped or completely flat back surface to their patella (= patellar dysplasia). An abnormally shaped patella + trochlear groove together, at the same time, is termed ‘patellofemoral dysplasia’.

How do you fix patellar tracking?

Most patellar tracking problems can be treated effectively without surgery. Non-surgical treatment may include rest, regular stretching and strengthening exercises, taping or bracing the knee, using ice, and short-term use of non-steroidal anti-inflammatory drugs (NSAIDs).

What is the treatment for a dislocated patella?

Early treatment includes: Physical Therapy with an emphasis on strengthening the quadriceps (the muscles of the thigh) Bracing and taping – Special knee braces are designed to control how the kneecap moves. Surgery – Some patients may need surgery, especially if they have a lot of pain or repeated dislocations.

What does Ballotable mean?

(also ballotable) Medicine. Detectable by ballottement; moving in response to ballottement.

What does ballottement mean?

Medical Definition of ballottement : a sharp upward pushing against the uterine wall with a finger inserted into the vagina for diagnosing pregnancy by feeling the return impact of the displaced fetus also : a similar procedure for detecting a floating kidney.

What is patellar tracking syndrome?

Patellar tracking refers to the dynamic relationship between the patella and trochlea during knee motion [1]. Patellar maltracking occurs as a result of imbalance of this relationship often secondary to anatomic morphologic abnormality. Usually, young individuals, particularly women, suffer the consequences of this disorder [2].

What is patellar tendinitis?

Patellar tendinitis. Print. Patellar tendinitis is an injury to the tendon connecting your kneecap (patella) to your shinbone. The patellar tendon works with the muscles at the front of your thigh to extend your knee so that you can kick, run and jump.

Why is the lateral articular surface of the patella more prominent?

The lateral trochlear articular surface is usually more prominent than its medial portion. As the knee joint ranges from extension to flexion, the articular surface area of the patella is in contact with the femur changes.

Which two features are associated with patellar maltracking?

The two features are associated with patellar maltracking Advantages of CT over plain radiography include its cross-sectional capability and ability to generate multiplanar reformations. This allows for greater detailed evaluation of the patellar and trochlear morphology, patellofemoral relationship, and status of the joint.
