Debridement and implant retention in acute hematogenous periprosthetic joint infection after knee arthroplasty: a systematic review.

Debridement, antibiotic, and implant retention (DAIR) can be used as a first surgical procedure for acute infections in patients who have well-fixed components. However, its use in hematogenous or late acute infections is still debated. This systematic review of literature aims to clarify the effectiveness of DAIR procedure in the treatment of hematogenous periprosthetic knee infections.

Return to sports after medial unicompartmental knee arthroplasty in patients with concomitant patella-femoral osteoarthritis: multicenter retrospective cohort study with minimum 5-year follow-up.

Purpose: The purpose of our study was to evaluate clinical outcomes and return to sports after medial unicompartmental knee arthroplasty (UKA) in middle-aged active patients with concomitant patella-femoral joint (PFJ) osteoarthritis at time of surgery.

Methods: One-hundred and fifty-one patients who underwent medial fixed-bearing cemented UKA, between 2012 and 2015, for medial unicompartmental osteoarthritis of the knee, were retrospectively reviewed with a minimum 5-year follow-up. The mean age at surgery was 54.

An Ego Depletion Account of Aging Stereotypes' Effects on Health-Related Variables.

Objectives: This study examined whether stereotypes may predict health outcomes independently from their internalization into the self. Specifically, we tested whether endorsement of negative age stereotypes in the physical activity (PA) domain is related to decreased subjective vitality among active older adults, illustrating ego depletion.

Method: This longitudinal study included 192 retired individuals aged 60-92 years who regularly participated in organized PA, and who completed the measures on three occasions (9-month period).
