While true knee dislocations (tibiofemoral) are rare, dislocations of the patella out of the trochlear groove on the femur are common. While these are usually easily reduced on the sideline or emergency department, recurrent instability can occur. While initial non-operative management can be recommended for first-time dislocations without evidence of severe cartilage injury or loose body, surgical intervention can be recommended for recurrent injuries or concomitant damage.
PATELLA DISLOCATIONS WITH CARTILAGE INJURY MAY REQUIRE SURGERY
This paper reviews the natural history and treatment options for patella dislocations in young athletes.
PATELLA DISLOCATIONS ARE COMMON IN MILITARY PERSONNEL
This epidemiologic study reported injury rates 10 times higher in the military population than civilian populations. Women were 61% more likely to sustain patella dislocations.
PRIMARY PATELLA DISLOCATIONS MAY REQUIRE SURGERY
This case series of patients undergoing surgical intervention following first-time patella dislocation highlights the importance of early clinical assessment and advanced imaging. These patients experienced significant cartilage injuries requiring repair or loose body removal as well as MPFL reconstruction.
MORE THAN HALF OF PATELLA DISLOCATION OCCUR DURING SPORTS
Query of national emergency room database showed that more than half of patella dislocations occurred during athletics. The peak incidence was in the 15-19 year old group with female and males having similar risk.
