Minimum Five-Year Outcomes with Porous Tantalum Acetabular Cup and Augment Construct in Complex Revision Total Hip Arthroplasty.
The use of a trabecular metal revision shell with metal augmentation to fill segmental or irregular defects during complex revision hip arthroplasty has been shown to provide good short-term results in prior published series. Longer-term results of the several cup-augment constructs used clinically are not known. The objective of this study was to report, with minimum 5-year radiographic and clinical follow-up, the outcome of these various constructs in revision total hip arthroplasty. ⋯ Therapeutic Level IV.

Impact of Preoperative Opioid Use on Total Knee Arthroplasty Outcomes.
There is growing concern about the use of opioids prior to total knee arthroplasty (TKA), and research has suggested that preoperative opioid use may lead to worse pain outcomes following surgery. We evaluated the pain relief achieved by TKA in patients who had and those who had not used opioids use before the procedure. ⋯ Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Fracture Prevention in the Orthopaedic Environment: Outcomes of a Coordinator-Based Fracture Liaison Service.
Fracture liaison services focus on secondary fracture prevention by identifying patients at risk for future fracture and initiating appropriate evaluation, risk assessment, education, and therapeutic intervention. This study describes key clinical outcomes including bone mineral densitometry, physician assessment, and pharmacotherapy initiation in pharmacotherapy-naïve patients undergoing treatment for fragility fracture in a Canadian fracture liaison service. ⋯ Fracture prevention programs are currently engaged in establishing and modifying fracture liaison services in a quest for practical and effective models. The program described in this article exemplifies a coordinator-based model that produced good outcomes.

Multicenter StudySynovial Fluid Cell Count for Diagnosis of Chronic Periprosthetic Hip Infection.
There is a paucity of data regarding the threshold of synovial fluid white blood-cell (WBC) count and polymorphonuclear cell (neutrophil) percentage of the WBC count (PMN%) for the diagnosis of chronic periprosthetic joint infection (PJI) after total hip arthroplasty. Despite this, many organizations have provided guidelines for the diagnosis of PJI that include synovial fluid WBC count and PMN%. We attempted to define a threshold for synovial fluid WBC count and PMN% for the diagnosis of chronic PJI of the hip using a uniform definition of PJI and to investigate any variations in the calculated thresholds among institutions. ⋯ Diagnostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Retracted Publications in Orthopaedics: Prevalence, Characteristics, and Trends.
Retracted publications are a crucial, yet overlooked, issue in the scientific community. The purpose of our study was to assess the prevalence, characteristics, and trends of retracted publications in the field of orthopaedics. ⋯ Greater awareness of the COPE guidelines within the orthopaedic community and more efficient means to prevent the citation of retracted articles are needed.
