Chapleau J, Lambert B, Sullivan T, et al. - This study was attempted to ascertain whether the nature and magnitude of alignment correction (ΔAlign°) performed during primary total knee arthroplasty (TKA) had an impact on bone mineral density at the metaphysis of the distal femur (DFmr) and proximal tibia (PTb). Researchers included a total of 71 individuals who had undergone full-length standing x-rays and knee-specific BMD measurements applying dual-energy-x-ray-absorptiometry before and 3 and 6 months following TKA. According to the findings, valgus individuals showed decreased medial BMD at DFmr and PTb and exhibited sustained improvements 6 months post-surgery. When correcting valgus malalignment, mechanical axis correction may be clinically impactful to bone remodeling.
