A Longer Duration of Intravenous Antibiotic Treatment for Patients with Early Periprosthetic Joint Infections Is Not Associated with a Lower Failure Rate.

Background: In recent years, many studies have demonstrated the efficacy of an early switch to oral antibiotics after surgical treatment in orthopedic-related infections. However, large analyses on periprosthetic joint infections (PJIs) are lacking.

Material And Methods: We conducted a retrospective observational multicenter study in patients diagnosed with an early post-operative PJI, defined as one occurring <3 months after the index arthroplasty and treated with debridement, antibiotics, and implant retention (DAIR).

Lower risk of revision in fixed-bearing compared to mobile-bearing total ankle arthroplasties: A register based evaluation of 1246 patients in the Netherlands.

Background: Total ankle arthroplasty (TAA) has been developed as treatment for disabling tibiotalar osteoarthritis. TAAs are divided into mobile- and fixed-bearings. The aim was to determine the incidence and trends of fixed- and mobile bearings over time and investigate the association of bearing type and risk of revision after primary TAA in the Netherlands.

Motor inhibition during voluntary gait initiation in young and older adults.

Based on a novel approach, this study explores feasibility and relevance of an inhibition task for studying age-related differences in motor inhibition during gait initiation. When presented with a go-signal, young adults (YA, n = 24) and older adults (OA, n = 55) were required to promptly initiate gait. Participants completed 3 blocks of 12 gait trials.

Predicting periprosthetic joint infection: external validation of preoperative prediction models.

: Prediction models for periprosthetic joint infections (PJIs) are gaining interest due to their potential to improve clinical decision-making. However, their external validity across various settings remains uncertain. This study aimed to externally validate promising preoperative PJI prediction models in a recent multinational European cohort.

What Is the Most Optimal Bearing Surface for Minimizing Instability After Revision Total Hip Arthroplasty?

Based on the results of our meta-analysis, dual mobility implants appear to have the most efficacy in preventing instability following revision total hip arthroplasty. Notwithstanding, given the relatively small sample sizes of the included studies, in conjunction with heterogeneity in study design, it is important to recognize that further large randomized controlled trials are necessary to determine the optimal bearing surface to reduce the risk of instability after revision total hip arthroplasty.
