Patellar Dislocation in the United States: Role of Sex, Age, Race, and Athletic Participation

“…3,7,9,43 While the exact mechanism of injury is unspecified in the current study, previous studies have shown that patellar dislocation most commonly occurs as a result of noncontact, valgus-flexion-external rotation mechanism on a planted foot during cutting or pivoting movements. 35,[43][44][45] Activities of daily living account for approximately one-fourth of all injuries in the current study, which closely corresponds to the 21% reported by Atkin et al 35 A direct blow to the knee is a rare cause of patellar dislocation, accounting for only 7% of all injuries. 35 The NEISS is an established model for epidemiological surveillance of orthopedic injuries.…”

Epidemiology of Patellofemoral Instability Injuries Among High School Athletes in the United States

“…This finding contrasts the traditional thought that PFIs most commonly occur via a noncontact valgus-flexion-external rotation mechanism on a planted foot during pivoting. 2,20,28,33,34 Atkin et al 2 found that twothirds of sports-related patellar dislocations occurred during level 1 cutting or pivoting sports. However, those authors also reported that only 7% of all patellar dislocations were caused by a direct blow to the knee.…”
