A Case Report of Acute Achilles Tendon Rupture in a Patient With Multimorbidity Treated With Endoscopic Flexor Hallucis Longus Transfer.

Acute Achilles tendon rupture (AATR) in patients with multimorbidity poses a significant therapeutic challenge to surgeons because of the increased risk for wound-healing-related complications. Thus, nonoperative management has been these individuals' most widely adopted treatment. We report a case of a 66-year-old patient with AATR who was treated with endoscopic flexor hallucis longus (FHL) transfer. His medical history was remarkable for recent stroke, hypertension, prediabetes, pemphigus under oral methylprednisolone, smoking, and recent pneumonia. The patient was evaluated up to two years postoperatively and was satisfied with the outcome since he was able to maintain his pre-traumatic activity level. No complications were noted. The Achilles tendon total rupture score was 92 out of a maximum of 100. This favorable outcome indicates that endoscopic FHL transfer may be a safe alternative treatment option for patients with an increased risk of surgical complications.
