The management of acute Achilles tendon rupture has been well established and is often treated with interrupted tenorrhaphy. While surgical site infection, rerupture and ankle contracture has been reported as potential complications, the tendon often heals uneventfully, and reports of complication other than mentioned above are extremely rare. We report a case of a common peroneal nerve injury which occurred after Achilles tendon repair surgery. The injury may have occurred following compartment syndrome from the anteriorly place long leg splint. To our knowledge, this is the first report in the literature.

23-year old male tae-kwon-do athlete visited with both Achilles tendon rupture after landing both lower limbs at the same time performing kick motion on the same day. Rt. achilles tendon was treated with open tenorrhapy by modified Bunnel method, and Lt. achilles tendon was treated with minimal invasive suture with Achillon. In young tae-kwon-do athlete both Achilles tendon rupture is very rare without any causing factors. From this case, we need to consider the possibilities of both Achilles tendon rupture in young patients during exercise and precaution is needed especially in landing movement.
