Value of passive anterior tibial subluxation on axial MRI in identifying anterior cruciate ligament functional deficiency in patients with advanced anteromedial osteoarthritis of the knee: a case-control study

Table 1 Demographics and Characteristics of the Included Patients

Variables	ACLI Group (n = 45)	ACLD Group (n = 40)	P-value
Age (years)	64.27 ± 8.55	69.35 ± 7.90	< 0.01
Sex (n)			0.80
Male	10	8
Female	35	32
Knee side (n)			0.80
Left	26	22
Right	19	18
Knee flexion degree (°)	112.3 ± 15.4	111.4 ± 16.0	0.79
Knee varus degree^a (°)	7 (5, 8)	6 (3, 7.25)	0.17

Variables with “^a” are presented as median (interquartile range) and compared using the Mann-Whitney U test. ACLI, anterior cruciate ligament functionally intact; ACLD, anterior cruciate ligament functionally deficient. Bolded values indicate statistical significance (P < 0.05)
