Patellar clunk
A patellar clunk is an uncomfortable clunk noise (and feeling) around the patella, usually associated with certain types of knee replacement, and due to scarring above the patella.
Patellar dislocation
Patellar dislocation (dislocated kneecap) is a painful and distressing event, when the patella jumps clean out of the restraining walls of the groove in which it normally rides.
Patellar dysplasia
Patellar dysplasia means an abnormally-shaped patella (kneecap).
Patellar fracture
A patellar fracture is a traumatic break of the patella bone (kneecap).
Patellar instability
Patellar instability is when the kneecap does not ride smoothly throughout its excursion in the underlying groove of the femur, popping over to one side, or even de-railing.
Patellar malalignment
Patellar malalignment is present when the kneecap - for whatever reason - does not sit optimally in the underlying groove as the knee bends and straightens.
Patellar mobilisations
Patellar mobilisations are soft tissue stretches around the kneecap that prevent adhesions from tethering it down and causing a stiff knee.
Patellar resurfacing
Patellar resurfacing is a surgical procedure to replace the joint surface of the patella.
Patellar retinaculum
The patellar retinaculum is the fibrous material at the sides of the patella, that act to stabilise it.
Patellar subluxation
Patellar subluxation is when the patella rides suddenly up the side of its groove, but does not fully dislocate.
