2023 Annual Meeting Knee Access Pass-Opinion: The TTO Must Be Added!

Video Transcription

Video Summary

Jackie Brady discusses when to add a tibial tubercle osteotomy (TTO) alongside MPFL reconstruction, emphasizing risk factors like J sign, patella alta, and borderline high TTTG. Studies show a 5% failure rate in isolated MPFL, with patella alta and positive J sign predicting failure. The J sign is three-dimensional, linked to malalignment, trochlear dysplasia, and worse outcomes. Brady suggests TTO for malalignment in coronal, sagittal, or rotational planes, especially in patients with collagen disorders or asymmetrical anatomy. The ongoing JUPITER study aims to provide multicenter data to refine treatment and failure definitions.
