A Technique of Predicting Radiographic Joint Line and Posterior Femoral Condylar Offset of the Knee

Table 2

A comparison of radiographic measurements and ratios for male and female genders.

	Male (𝑛=45)	Female (𝑛=60)	Difference	95% CI	𝑃 value*
Joint line (mm)	65.5 (4.5)	61.9 (4.8)	3.6	0.1 to 7.1	0.045
PCO (mm)	26.5 (3.1)	24.7 (2.8)	1.8	−0.5 to 4.0	0.12
Femoral diaphysis (mm)	35.5 (2.0)	31.8 (2.5)	3.6	1.9 to 5.4	<0.0001
Joint line ratio	1.85	1.95	0.1	−0.06 to 0.18	0.1
PCO ratio	0.75	0.78	0.03	−0.01 to 0.06	0.32
