Examination showed a positive dial test at 30\u00b0 and 90\u00b0 and varus thrust gait. Imaging revealed anterolateral tibial plateau deficiency with external rotatory subluxation. Staged treatment involved gradual correction using a hexapod external fixator followed by patient-specific 3D guided intra-articular osteotomy and posterolateral corner reconstruction. He regained knee stability and returned to full activity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n
