En la búsqueda de predictores que nos ayuden a obtener un mejor resultado en la cirugía de revisión de ligamento cruzado anterior

Abstract

Introduction: risk factors for ACL rupture are technical errors, graft characteristics, meniscal and chondral injuries, or untreated injuries. The objective of our work was to recognize modifiable predictors that help us obtain a better result in ACL revision surgery.

Materials and methods: cross-sectional descriptive study. Series of patients treated at our center between 2011 and 2021 who underwent ACL revision surgery. Age, sex, traumatic or non-traumatic primary surgery failure, fixation used, location of both tunnels, graft used in primary surgery, old and new chondral and meniscal joint injuries and type of graft used in revision surgery were recorded.

Results: a total of one hundred and nine patients were analyzed. Most often, male patients underwent revision between the ages of twenty and forty. The main traumatic cause was sports practice (40.37%), followed by traffic accident or at home (7.33%) and in the work environment (24.8%), and without demonstrable cause (27.5%). Isolated femoral tunnel malposition was the most common technical failure at 41.29%, no technical error at 38.53%, and isolated tibial tunnel placement failure at 2.75%. In all the patients evaluated, 28.44% (thirty-one patients) did not present a previous or current meniscal lesion; while 71.56% (seventy-eight patients) showed some type of injury. Graft choice was H-T-H autograft (30.28%), posterior tibial allograft (30.28%), anterior tibial allograft (19.27%), ST-RI autograft (11.01%), and other Achilles, fibular, and ST allografts (9.17%)

Discussion: more studies will be necessary to determine if this failure rate persists despite our greater knowledge of the technique and various aspects of revision surgery.
