Routine lateral radiographs of the injured knees were utilized to measure the following parameters: LFC ratio (LFCR), height of LFC to anteroposterior diameter ratio (HAPR), femur tibia size ratio (FTSR), tibia to posterior femoral condyle ratio (TPFCR) and Porto ratios (XY\/AB; B\/AB; B\/XY). Malrotated radiographs were excluded. Pearson's correlation coefficients were used to identify relationships. Intraclass correlation coefficients were calculated for inter\u2010 and intraobserver reliability for two raters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fifty\u2010eight patients were included.

Intraobserver agreement was excellent for LFCR, HAPR, FTSR, TPFCR and B\/AB and good for XY\/AB and B\/XY.
