Achilles Tendon Rupture

Achilles tendon rupture is the most common tendon rupture in the lower extremity. The injury most commonly occurs in adults in their third to fifth decade of life. Acute ruptures often present with sudden onset of pain associated with a "snapping" or audible "pop" heard at the injury site. Patients can describe the sensation of being kicked in the lower leg. The injury causes significant pain and disability.

Achilles tendon injuries predominantly occur in individuals who engage in sporadic physical activity, often referred to as "weekend warrior" athletes, and they most frequently occur during soccer, racket games, or basketball. These injuries are reportedly misdiagnosed as ankle sprains in 20% to 25% of patients. The age group most commonly affected by Achilles tendon injuries falls within the third to fifth decade of life. Approximately 10% of patients report experiencing prodromal symptoms before the injury. Additionally, several recognized risk factors include prior intratendinous degeneration (eg, tendinosis), fluoroquinolone use, steroid injections, and inflammatory arthritides.
