Bone Quality

Cemented and cementless components will affect the bone differently, because of the bone in-growth in the cementless design compared to cemented.

Periprosthetic bone mineral density (BMD) can be measured by local knee dual-energy X-ray absorptiometry (DXA) scans. If the BMD is affected negatively it will increase the risk of later failure in terms of loosening or fractures.
Bone remodeling and bone loss can be measured by blood samples (bone turnover markers; enzymes and proteins from bone resorption and formation).

We are investigating if the bone quality, in terms of blood samples, BMD and DXA, has an affect on the survival of the implants.
