Several radiological measurements have been described.<\/jats:p><jats:p>\n          Purpose\u2003In this study, we illustrate a new linear measurement: The linear coronal knee offset (LCKO) that can be used to analyze the coronal configuration on long leg alignment radiographs commonly undertaken during preoperative templating.<\/jats:p><jats:p>\n          Methods\u2003A retrospective search was performed of our Picture Archiving and Communication System and Radiology Information System to identify 100 lower limbs anteroposterior, weight bearing, long leg alignment view radiographs of patients referred to knee clinics over 1 year with knee pain.<\/jats:p><jats:p>Demographic details, clinical indication, standard radiological measurement of the anatomical tibiofemoral angle, and the LCKO were measured and data were analyzed using Student's t-test. In addition, intraclass correlation coefficient was used to analyze for intraclass reliability.<\/jats:p><jats:p>\n          Results\u2003The average age of patients was 36.3 years (range: 12\u201380 years) with a male predominance. The LCKO was statistically significant between the three cohorts of patients. The mean LCKO in normal cohorts was 0.24\u2009cm, varus was \u22120.6\u2009cm, and valgus was 1.72cm.
