Purpose: The relationship between knee osteoarthritis (OA), bone mineral density (BMD), and alignment has not yet been clarified. This study aimed to investigate the relationship between the two limbs in patients with single-limb knee OA.
Methods: Patients who underwent single-limb total knee arthroplasty between March 2019 and February 2021 were retrospectively analyzed. Only patients with Kellgren-Lawrence (KL) grades III and IV on the operated side and KL I and II on the opposite side were included. Patients with traumatic OA, a surgery that could change the alignment of both lower extremities and previous fractures were excluded. The proximal femur BMD on the OA and non-OA sides were compared. In addition, the difference in BMD was compared between a group with a difference in alignment of both lower extremities (> 5°) and a group without a difference (< 5°).
Results: In total, 149 patients were included. The BMD T-score of the femoral neck on the OA side was lower than that of the non-OA side (p < 0.001). There was no correlation between BMD and alignment, and there was no difference in BMD according to the difference in alignment.
Conclusion: The femoral neck BMD of the leg on the side with knee OA was lower than that on the side without OA. However, the alignment difference between the legs did not affect BMD. BMD was lowered because of OA and not because of alignment.

Phosphatidylcholine is a ubiquitous phospholipid. It contains a phosphocholine (PC) headgroup and polyunsaturated fatty acids that, when oxidized, form reactive oxidized phospholipids (PC-OxPLs). PC-OxPLs are pathogenic in multiple diseases and neutralized by anti-PC IgM antibodies.

This paper presents a review of the potential role of the endoplasmic reticulum/Golgi complex and intracellular vesicles in mediating events leading to or associated with vertebrate tissue mineralization. The possible importance of these organelles in this process is suggested by observations that calcium ions accumulate in the tubules and lacunae of the endoplasmic reticulum and Golgi. Similar levels of calcium ions (approaching millimolar) are present in vesicles derived from endosomes, lysosomes and autophagosomes.

Background: Zoledronate prevents fractures in older women when administered every 12 to 18 months, but its effects on bone density and bone turnover persist beyond 5 years. Whether infrequent zoledronate administration would prevent vertebral fractures in early postmenopausal women is unknown.
Methods: We conducted a 10-year, prospective, double-blind, randomized, placebo-controlled trial involving early postmenopausal women (50 to 60 years of age) with bone mineral density T scores lower than 0 and higher than -2.

Objective: This study aimed to assess the effects of a single-dose radiation therapy (15 Gy) on grafted and non-grafted defects, bone microarchitecture, and collagen maturity.
Methodology: Bone defects were surgically created in rat femurs. The right femur defect was filled with blood clot (group "Clot") and the left femur defect by deproteinized bovine bone mineral graft (group "Xenograft").
