The present modified trochleoplasty technique, known as the \u201cBrazilian trochleoplasty,\u201d is a reproducible technique developed by the Brazilian Storm Knee Research Group, which reshapes the trochlear groove while preserving cartilage integrity. Our technique is indicated for patients with recurrent patellar dislocation; abnormal patellar tracking, such as the J\u2010sign; and high\u2010grade trochlear dysplasia classified as Dejour types B and D, with trochlear prominence greater than 5 mm. This approach creates a single central sulcus without additional osteotomies, simplifying the procedure while ensuring anatomic precision. Fixation is achieved using headless compression screws, enhancing stability while minimizing cartilage damage. Compared with traditional sulcus\u2010deepening techniques, the modified trochleoplasty offers a more accessible and effective alternative, improving patellar stability and reducing complications such as stiffness. Its stepwise methodology facilitates reproducibility, making it a viable option for young, active patients with severe trochlear dysplasia.<\/jats:p>\n                  <\/jats:sec>\n
