A Finnish study published in The Journal of Bone and Joint Surgery, British Volume analyses the long-term survival of 12 of the most common combinations of components in cemented total hip replacements for osteoarthritic patients over 55. The authors conclude that that there are 'considerable differences in the long-term survival of cemented prostheses in patients aged 55 years or older in Finland'.

A standard measure of excellent long-term survival is a revision rate of less than 10%. The variance in results for the 12 combinations was quite wide especially between different age groups within the study. For patients older than 74 years all of the cemented designs produced a reliable outcome and yet for patients aged between 55 and 64 years none of the designs offered excellent long-term survival (≥ 90%).

The combination of components that had the best long-term outcome across all of the age groups was the Exeter Universal/Exeter All-poly design with a survival rate of 88% at 15 years. The authors are unclear as to 'the potential reasons for the relatively poor long-term survival rate of cemented hip designs in Finland'. Other studies have suggested that for osteoarthritic patients aged 55 to 74 cemented prostheses have a higher risk of revision for aseptic loosening than cementless implants. However, this study points to low volume hospitals and less use of third generation cementing techniques as possible causes.
