Injury Fact Sheet: Patellar Subluxation

By on December 30, 2012

Description:knee dislocation

Patellar Subluxation is a partial dislocation of the patella (kneecap).  In this condition, the patella relocates on its own.  While more than one review studies point to patellar subluxation as a commonly occurring injury in dancers, there is little direct research on patellar subluxation in dancers.


Causes & Prevention:

Patellar subluxation appears to occur more commonly in adolescent females who are hyperflexible at the knee joint.  It is especially important in these individuals to make sure that the use of turnout is initiated at the hip and not the knee.  Patellar subluxation can also occur as a secondary condition from improper or incomplete rehabilitation of an acute patellar dislocation.


Of Note:

In a study comparing physically active young adults with patellar dislocation, subjects who received both surgical and non-surgical interventions admitted to patellar subluxation at a seven-year follow up.  Of the 21 subjects who received non-surgical interventions, 4 had patellar subluxation at follow up and 2 of the 17 subjects who underwent surgical restabilization of the patella following dislocation later developed patellar subluxation.
