Description
Müjgan Yilmaz Altun and co-authors followed in 2026 bone density around replacement knee joints in a randomized trial's secondary analysis. Sixty-three patients received either a cemented or an uncemented knee implant with an asymmetric shinbone part. Density was scanned at several points over two years in three zones of the thighbone and shinbone. Changes within patients and differences between groups were tested statistically.
Bone density fell around both implant types, most clearly in the front zone of the thighbone. That zone lost about a third of its density with uncemented fixation, notably more than with cement. Other thighbone zones lost less, and between-group gaps there were not clear. Shinbone changes stayed small, with only one clear decline under cemented parts. The authors judge the shinbone findings to be of uncertain importance for patients.
