Fluoroscopy-guided direct anterior approach total hip arthroplasty provides more accurate component positions in the supine position than in the lateral position

Table 3 The mean and standard deviation of femoral offset, global offset, and absolute difference of Leg length discrepancy after postoperative in S-DAA and L-DAA were described

Variables	S-DAA	L-DAA	P value
Femoral offset difference(mm)	2.4 ± 0.69	3.2 ± 0.47	＜0.001^a
Global offset difference(mm)	1.1 ± 0.46	1.6 ± 0.51	＜0.001^a
Leg length discrepancy(mm)	2.1 ± 0.42	4.3 ± 0.43	＜0.001^b

S-DAA direct anterior approach in the supine position, L-DAA direct anterior approach in the lateral position
