Based on data from the existing literature, we can safely suggest that bone mineral changes around cementless and cemented conventional femoral stems, and conservative femoral stems, are not predictive of either satisfactory or unsatisfactory total hip arthroplasty long term clinical outcomes. Additionally, studies with a follow up shorter than 5–10 years are perhaps clinically irrelevant. These observations may be helpful in interpreting the existing literature.
