Artrodesis tibiotalar mediante artroscopia posterior en paciente con la enfermedad de Klippel-Trénaunay

Abstract

Posterior arthroscopic ankle arthrodesis in a patient with Klippel-Trénaunay syndrome Anterior arthroscopic arthrodesis has been proven as a safe technique with a high union rate. In certain cases, an anterior arthroscopic approach can be contraindicated by skin lesions. Klippel-Trénaunay syndrome is a complex malformation characterized by the clinical triad of haemangiomas, venous and lymphatic anomalies and hypertrophy of bones and soft tissues of usually one lower limb. Venous malformations cause an excessive blood loss during orthopaedic procedures, requiring copious blood transfusion. In this case, anterior portals were not possi-ble to perform due to the vascular malformations. The procedure was performed with the patient in the prone position and the use of 2 posterior portals. The articular surfaces were debrided by removing the cartilage by arthroscopic means, and the joint was fixed with 2 crossed screws. Fusion was completely achieved at 6 months fol-low-up. At 2-year follow-up, patient is pain free and able to walk long distances.
