Kuwada classification of achilles tendon tear

This classification was proposed by Kuwada in 19904 and at the time of writing (July 2016) remains the most widely used system for describing achilles tendon rupture. 

Achilles tendon tears may be grouped (according to severity of the tear and degree of retraction) into 4 types:

  • type I: partial ruptures ≤50%
    • typically treated with conservative management
  • type II: complete rupture with tendinous gap ≤3 cm
    • typically treated with end-end anastomosis
  • type III: complete rupture with tendinous gap 3 to 6 cm
    • often requires tendon/synthetic graft
  • type IV: complete rupture with defect of >6 cm (neglected ruptures)
    • often requires tendon/synthetic graft and gastrocnemius recession
