Article Synopsis
  • The study assessed changes in bone mineral density (BMD) in the proximal tibia of 69 patients after total knee arthroplasty (TKA) surgery for osteoarthritis, using dual-energy X-ray absorptiometry (DXA) scans at various intervals.
  • Results showed that varus-aligned knees had higher initial BMD, but experienced a significant decrease post-surgery, while valgus-aligned knees had a slight, non-significant increase. Overall, both groups ended up with similar BMD in medial and lateral compartments after alignment correction.
  • The researchers concluded that proper valgus alignment during TKA is crucial for enhancing tibial bone strength and potentially increasing the longevity of the prosthetic components

The clinical survival of joint arthroplasties is related to the quality of the surrounding bone environment. Bone mineral density (BMD) is an important measure of bone strength and quality. The aim of this prospective study was to measure the quantitative changes in BMD in the distal femur after cemented total knee arthroplasty (TKA) in osteoarthrotic knee joints.

In this prospective 5-year study, we determined the periprosthetic bone loss after cemented total hip arthroplasty (THA) in 15 patients using dual energy X-ray absorptiometry (DXA). A reduction in the periprosthetic bone mineral density (BMD) of 5-18% occurred in all Gruen regions, or regions of interest (ROI), during the first 3 months after THA. The bone loss continued up to 6 months in almost all ROIs.
