Aseptic loosening is one of the major reasons for late revision in total knee arthroplasty (TKA). The risk of aseptic loosening can be detected using radiostereometric analysis (RSA), whereby micromovements (migration) can be measured, and thus RSA is recommended in the phased introduction of orthopedic implants. Decrease in bone mineral density (BMD), as measured by dual-energy x ray absorptiometry (DXA), is related to the breaking strength of the bone, which is measured concurrently by RSA. The aim of the study was to evaluate bone remodeling and implant migration with cemented asymmetrical tibial and uncemented femoral components after TKA with a follow up period of 2 years.This was a prospective longitudinal cohort study of 29 patients (number of female/male patients 17/12, mean age 65.2?years), received a hybrid Persona® TKA (Zimmer Biomet, Warsaw, IN, USA) consisting of a cemented tibial, an all-polyethylene patella, and uncemented trabecular metal femoral components. Follow up: preoperative, 1 week, and 3, 6, 12 and 24?months after surgery, and double examinations for RSA and DXA were performed at 12?months. RSA results were presented as maximal total point of motion (MTPM) and segmental motion (translation and rotation), and DXA results were presented as changes in BMD in different regions of interest (ROI).MTPM at 3, 6, 12, and 24?months was 0.65?mm, 0.84?mm, 0.92?mm, and 0.96?mm for the femoral component and 0.54?mm, 0.60?mm, 0.64?mm, and 0.68?mm, respectively, for the tibial component. The highest MTPM occurred within the first 3?months. Afterwards most of the curves flattened and stabilized. Between 12 and 24?months after surgery, 16% of femoral components had migrated by more than 0.10?mm and 15% of tibial components had migrated by more than 0.2?mm. Percentage?change in BMD in each ROI for distal femur was as follows: ROI I 26.7%, ROI II 9.2% and ROI III 3.3%. BMD and at the proximal tibia: ROI I 8.2%, ROI II 8.6% and ROI III 7.0% after 2 years compared with 1 week postoperative results. There was no significant correlation between maximal percentwise change in BMD and MTPM after 2 years.Migration patterns and changes in BMD related to femoral components after TKA in our study correspond well with previous studies; we observed marginally greater migration with the tibial component.
