Epidemiology and Demographics

In a journal by the Department of Orthopaedic Surgery, Brian Waterman collected incidence rate data in respect to sex, age and race in the U.S. Patellar dislocations have been estimated to occur among an at risk –population of 1,774,210,081 people per year.[1]

Age

The breakdown of the incidence rates found in AM J sports medicine journal, among the ages of 10–17 years old were found to be about 29 per 100,000 persons per year, while the adult population average for this type of injury ranged between 5.8 and 7.0 per 100,000 persons per year.[2] The highest rates for this type of injury were found in the youngest age groups, while the rates declined with increasing ages.

Gender

Females are more susceptible to patellar dislocation.

Race

Race is a significant factor for this injury, where Hispanics, African-Americans and Caucasians had slightly higher rates of patellar dislocation due to the types of athletic activity involved in basketball 18.2%, soccer 6.9% and football 6.9%, according to Brian Waterman.[1]
