Factors that may increase your risk of Achilles tendon rupture include:

  • Age. The peak age for Achilles tendon rupture is 30 to 40.
  • Your sex. Achilles tendon rupture is up to five times more likely to occur in men than in women.
  • Playing recreational sports. Achilles tendon injuries occur more often in sports that involve running, jumping and sudden starts and stops — such as soccer, basketball and tennis.
  • Steroid injections. Doctors sometimes inject steroids into an ankle joint to reduce pain and inflammation. However, this medication can weaken nearby tendons and has been associated with Achilles tendon ruptures.
  • Certain antibiotics. Fluoroquinolone antibiotics, such as ciprofloxacin (Cipro) or levofloxacin (Levaquin), increase the risk of Achilles tendon rupture.
