More severe microdamage and micromechanical alterations: altered subchondral bone remodeling in varus knee osteoarthritis with osteoporosis.

Unlabelled: Previous studies show osteoporosis causes tibial varus in knee osteoarthritis patients. Our analysis of tibial plateau specimens from osteoarthritic patients reveals that osteoporosis accelerates the deterioration of the subchondral microstructure of the tibial plateau, exacerbating tibial varus.

Introduction: The relationship between osteoporosis (OP) and knee osteoarthritis (OA) has garnered significant clinical interest, particularly regarding the prevalence of tibial varus in patients suffering from both conditions.

Incidence of periprosthetic joint infection after primary total hip arthroplasty is underestimated: a synthesis of meta-analysis and bibliometric analysis.

The American Musculoskeletal Society updated the diagnostic criteria for periprosthetic joint infection (PJI) in 2011 and 2018. However, the overall incidence of PJI since the introduction of these new standards has not been assessed. In order to fill this knowledge gap, a single-group meta-analysis was conducted using articles obtained from several databases, focusing on the incidence of PJI after primary total hip arthroplasty (THA).
