A retrospective consecutive population of patients treated with conical tapered stems in cementless total hip arthroplasty for osteoarthritis due to congenital hip pathologies will be selected. The aim of this retrospective study is to evaluate the long-term clinical and radiographic results of this implant and the survival rates in such a specific cohort.
