Injuries to the lateral ligaments of the ankle complex are
among the most common injuries incurred by athletes.1
Lateral ankle sprains are thought to be suffered by men
and women at approximately the same rates; however, one
recent report2 suggests that female interscholastic and intercollegiate
basketball players have a 25% greater risk of incurring
grade I ankle sprains than their male counterparts. More
than 23 000 ankle sprains have been estimated to occur per
day in the United States, which equates to one sprain per
10 000 people daily.3 The most common predisposition to suffering
a lateral ankle sprain is the history of at least one previous
ankle sprain.4–8 In sports such as basketball, recurrence
rates have been reported to exceed 70%.4,9 Repetitive sprains
have also been linked to increased risk of osteoarthritis and
articular degeneration at the ankle.10,11
Residual symptoms after lateral ankle sprain affect 55% to
72% of patients at 6 weeks to 18 months.12,13 The frequency
of complications and breadth of longstanding symptoms after
ankle sprain has led to the suggestion of a diagnosis of the
‘‘sprained ankle syndrome’’14 and to the conclusion ‘‘that there
is no such thing as a simple ankle sprain.’’15 It has also been
estimated that 55% of individuals suffering ankle sprains do
not seek injury treatment from a health care professional.4,8
Thus, the severity of ankle sprains may often be underestimated
by athletes, and current treatment strategies for lateral
ankle sprains may not be effective in preventing recurrent injuries
or residual symptoms.
