Knee A to Z

A paste graft is a technique of cartilage repair, using cartilage and bone from a less important part of the knee joint and which has been ground up ('morcelised') and packed into the cartilage defect.

The patella is the kneecap, the bone sitting over the front of the knee. Plural = 'patellae'.

In patella alta the kneecap rides too high up on the femur (thigh bone). This may make it liable to sublux or even dislocate.

Patella baja is a kneecap that is positioned abnormally low in relation to the groove of the femur. It is also known as patella infera or infrapatellar contracture syndrome.

Patellae is the plural of 'patella', or 'kneecap'.

In patella infera the kneecap (patella) rides too low down the femur (thighbone).

Patellar is the adjective to describe things related to the patella.

Patellar alignment is the position of the kneecap relative to the groove in the underlying femur bone into which it slides when the knee is bent and straightened.

The patellar apprehension test is performed to confirm the doctor's suspicion of an underlying patellar instability, such as patellar subluxation or dislocation.

A patellar brace is a knee brace designed to stabilise or protect the kneecap.
