Epidemiology

Around 30% to 50% of musculoskeletal (tendon/muscle/bone) injuries presenting to physicians are tendon and ligament injuries.[2]

Among those injuries, acute ankle injury is one of the most common musculoskeletal injuries in athletes and sedentary people.[3][4] It has been estimated that ankle sprain has an incidence rate of 11.6 per 1000 exposures and a prevalence of 11.9%.[5][6]

In the US it accounts for an estimated 2 million injuries per year and 20% of all sports injuries.[3][4][7]

Approximately half of all ankle sprains occur during athletic activities.[8]

Incidence of ankle injury and ankle sprain may be higher in court games and team sports.[9] Males aged 15-24 years have a significantly higher incidence of ankle sprain than their female counterparts; females over 30 years had a higher incidence compared with their male counterparts.[8]
