Anatomical description of a new posterolateral double-window approach for the management of tibial plateau fractures.

INTRODUCTION

anatomical reduction and stable fixation are crucial in the treatment of articular fractures to prevent post-traumatic osteoarthritis and joint dysfunction. However, surgical exposure of the lateral tibial plateau remains a challenge, especially in the posterolateral column. New approaches are needed to provide adequate visualization of the articular surface. This study aims to anatomically describe a posterolateral double-window approach (anterior and posterior to the biceps femoris) in cadaveric specimens, optimizing surgical exposure without the need for osteotomies.

MATERIAL AND

METHODS

dissections were performed on two knee specimens, employing a posterolateral double-window approach (anterior and posterior to the biceps femoris). The exposed tibial surface was measured using a uniplanar ruler, and the percentages of lateral tibial plateau visualization were calculated.

RESULTS

in the left knee, the exposure of the anterolateral quadrant was 82%, and in the posterolateral quadrant was 66%. In the right knee, 70 and 66% were obtained, respectively. The anterolateral window provided greater exposure compared to the posterolateral one.

CONCLUSION

this technique represents a viable surgical option to optimize tibial exposure without osteotomies. Clinical studies are needed to validate its impact on functional recovery in patients.
