Patellar Subluxation
Patellar subluxation is also known as an unstable kneecap (patella), and often affects adolescents and younger children, though it can also occur in adults. Normally, as the knee bends, the knee cap, slides up and down in a groove, called the Trochlear Groove, on the end of the large thigh bone (femur). The kneecap is designed to fit in the center of this groove, and slide evenly within it, but in some individuals, the kneecap is pulled towards the outside of the knee, resulting in a knee cap which cannot track properly within the groove.
This may - but does not always - lead to the dislocation of the patella from the knee joint. Pain may extend beyond the knee cap itself, and can be quite uncomfortable with activity. If this occurs, always see a Health Care Professional for a proper diagnosis, treatment and proper follow-up care.
Preventive measures include wearing a patella strap or knee wrap to support your knee cap and the surrounding tissues during activity.
