RESUMEN
Multiligamentary knee injuries associated with transtibial amputation is a pathologie with a low incidence, so their diagnosis and treatment represent a great challenge for the medical team, mainly due to the low rate of scientific publications on the matter. This article intends to present the treatment of a really infrequent pathology, presenting the clinical case of a polytraumatized patient who suffered a left transtibial amputation associated with a multiligament knee injury with dislocation of the proximal tibiofibular joint. After analyzing the multiple therapeutic options, a specific surgical planning is carried out for the specific case of a multiligament knee injury associated with an ipsilateral transtibial amputation, proceeding to the execution of the reconstruction of the injury with good results. For this, several specific surgical gestures are carried out, adapted to the patient's condition, which will facilitate the surgery and are explained in the surgical technique. In conclusion, we must know that in order to obtain satisfactory results in these patients, it is important to carry out an early diagnosis and treatment of the injury, analyzing the proximal tibiofibular stability and providing adequate stability through the execution of a precise surgical technique.
