Objectives: The Polar Stem is the improved version of a stem already on the market. It has been implantet in both cementless and cemented versions for 15 years. Our clinic has been implanting it for 10 years. This is a first world-wide long-term follow-up of the cemented Polar stem.

Methods: A total of 113 hips replacements were performed in 106 patients between 10/2007 and 12/2009. The mean age of the patients at operation was 74.8 years, range 50-91 years. A mean 8.9 year follow-up has been achieved at in 98% of the cohort. Radiographic data and Harris Hip Score have been obtained during the survey.

Results and conclusion: Stem survival for any reason was 96.4% after 9 years, survival for aseptic loosening was 100%. Radiolucent lines up to 2 mm were observed in 75% patients, but osteolysis was not observed. Clinical outcomes were in line with previous investigations, and the rate of adverse events was very low. Cemented Polar stem is a modern stem with an excellent survival rate, very low rate of aseptic loosening giving the patient comparable or better quality of life.
