PurposeTo compare cemented versus cementless bipolar hemiarthroplasty in terms of operating time, blood loss, pain, functional outcome, morbidity, and mortality.MethodsMedical records of 207 patients aged ≥ 60 years who underwent bipolar hemiarthroplasty for displaced femoral neck fracture using a cemented (n=96) or cementless (n=111) prosthesis were reviewed. Postoperative thigh pain, ambulatory status, and complications were assessed.ResultsThe cemented group had significantly longer operating time (p=0.017) and greater intraoperative blood loss (p=0.024). Postoperative thigh pain was significantly higher in the cementless group (p=0.023).ConclusionCementless hemiarthroplasty is preferred over cemented hemiarthroplasty because of reduced operating time and intra-operative blood loss. It was associated with increased postoperative thigh pain, but functional outcomes, complications, and mortality were similar between the 2 groups.
