Introduction A well-fixed cement–bone interface is a crucial factor for acetabular and femoral components in cemented total hip arthroplasty (THA). The aim of the present study was to evaluate the middle-term clinical and radiological results of fixing the acetabular component with an interface bioactive bone cement (IBBC) technique in primary cemented THA. Materials and methods We undertook a retrospective review was undertaken of 193 primary cemented THAs in 174 patients using acetabular components cemented with an IBBC technique and followed for a minimum of 5 years (mean 8.3 years; range 5–17 years). Baseline data, clinical and radiological outcomes were evaluated. Results Japanese Orthopedic Association hip score and modified Harris hip scores demonstrated significant clinical improvement in all patients ( p
