Las lesiones osteocondrales de la articulación subtalar es una patología infrecuente y de incidencia variable, dado su reporte principalmente como hallazgo en el estudio de dolor crónico de tobillo y ya con cambios degenerativos articulares. La sospecha clínica y el estudio imagenológico dirigido, permiten investigar esas lesiones en estadios iniciales, evitando así el uso de técnicas que no preservan la articulación para su manejo. La artroscopía subtalar es una excelente herramienta tanto diagnóstica como terapéutica para la resolución de dichas lesiones. Dadas las características anatómicas y biomecánicas de la articulación, en estadios iniciales, el manejo mediante sinovectomía y microfracturas es una alternativa con excelentes resultados funcionales.

Este trabajo incluye dos casos de lesiones osteocondrales de la faceta posterior de la articulación subtalar manejadas vía artroscópica mediante sinovectomía y microfracturas y su posterior evolución.


Osteochondral lesions in the subtalar joint are an uncommon pathology with a variable incidence, being mainly reported as a finding in chronic ankle pain studies and with already visible degenerative joint changes at time of diagnosis. Clinical suspicion and directed imaging study, allows to investigate these lesions during early stages, thus avoiding the use of invasive techniques with scarce joint preservation. Subtalar arthroscopy is an excellent diagnostic and therapeutic tool for the resolution of these lesions. Given the anatomical and biomechanical characteristics of the joint, in the early stages the management by synovectomy and microfractures is an alternative with excellent functional results.

This study includes two cases of osteochondral lesions of the posterior facet of the subtalar joint managed through arthroscopically synovectomy and microfractures and their subsequent evolution.
