Prior leg length discrepancy in total hip arthroplasty patients causes greater implant complications and faster time to revision

Table 2 Two-year falls and implant-related complications between total hip arthroplasty patients with leg length discrepancy and a matched-control cohort

Complication	Leg length discrepancy (%)	Control (%)	OR	95%CI	P value
Falls	4.37	2.81	1.58	1.24-2.01	< 0.001
DL	6.33	2.53	2.61	2.10-3.24	< 0.001
ML	3.43	0.78	4.54	3.28-6.29	< 0.001
PFx	2.89	1.09	2.70	1.96-3.72	< 0.001

OR: Odds ratio; 95%CI: 95%confidence interval; DL: Dislocation; ML: Mechanical loosening; PFx: Periprosthetic fracture.
