Dual-mobility cups in THA demonstrate increased stability. Clinical outcomes following THA with dual-mobility cups have been reported, but gait has not been assessed. Therefore we performed a retrospective case control study to answer: (1) is gait better in patients following THA with a dual-mobility cup than in frail, elderly patients of the same age? (2) Are clinical outcomes better in patients following THA with a dual-mobility cup than in frail, elderly patients? (3) What is the dislocation rate following THA with a dual-mobility cup?Dual-mobility cupTotal hip arthroplastyOutcomesGait analysisTotal hip arthroplasty using a cementless dual-mobility cup provides increased stability and favorable gait parameters at five years follow-uptext::journal::journal article::research article
