Furthermore, post-operative wound healing problems, sometimes including infections, can be challenging to treat and negatively affect rehabilitation.Case Presentation: This 74-year-old lady suffered from insertional Achilles tendinopathy. After treatment with a local cortisone injection, she sustained a total insertional Achilles tendon rupture. This rupture was treated conservatively, and after treatment the Achilles re-ruptured in the insertional area. The rupture was then treated with re-insertion into the calcaneal insertion. Early in the post-operative period the patient sustained a deep surgical wound infection and sepsis. Because of poor effect of treatment with antibiotics, and total tendon destruction, the whole Achilles was extirpated. After extirpation there was immobilization in a cast followed by mobilization and gradually increased loading. At a one-year follow-up, the patient was walking without a limp, could do heel-raise halfway up standing on one leg, there was a palpable Achilles tendon and ultrasound scanning showed a structure very similar to a slightly thickened and tendinopathic Achilles tendon. There was an obvious regeneration of the whole Achilles tendon, and the tendon function was surprisingly good.Conclusion: This case study clearly shows the regeneration potential in the Achilles tendon and provides significant knowledge of importance for clinicians dealing with Achilles tendon injuries.Keywords: Achilles tendon, tendinopathy, Achilles rupture, infection, regeneration
