Chronic Opioid Use Independently Increases Complications and Resource Utilization After Primary Total Joint Arthroplasty.

Background: Current literature suggests a link between the chronic use of opioids and musculoskeletal surgical complications. Given the current opioid epidemic, the need to elucidate the effects of chronic opioid use (OD) on patient outcomes and cost has become important.

Relative frequency of primary total hip arthroplasty for avascular necrosis in the United States as compared to a regional center: A data review.

Background: The relative frequencies of indications for primary total hip arthroplasty (THA) are not well-established. This study aims to establish the incidence of THA performed for Avascular Necrosis of the hip (AVN), as well as the other most common indications for THA in the United States, as compared to the incidences at a high-volume tertiary referral center in Miami, Florida. We hypothesize that the relative incidence of AVN and each other indication for THA will vary significantly between the United States as a whole and the tertiary referral center.

Hospital Volume as a Source of Variation for Major Complications and Early In-Hospital Mortality After Total Joint Arthroplasty.

Background: Although the effects of hospital volume on mortality have been studied in other procedures, data on total joint arthroplasty (TJA) are limited. Furthermore, mortality rate among surgical patients with early major complications has become an important patient safety indicator and has been shown to be an important driver of mortality in certain operations. Our objective was to examine the effect of hospital volume on early complications and in-hospital mortality rate after TJA.

Assessment of Damage on a Dual Mobility Acetabular System.

Background: Dual mobility designs were introduced to increase stability and reduce the risk of dislocation, both being common reasons for surgical revision after total hip arthroplasty. The in vivo behavior of dual mobility constructs remains unclear, and to our knowledge, no data have been published describing in vivo surface damage to the polyethylene bearing surfaces.

Methods: We used surface damage assessed on the inner and outer polyethylene bearing surfaces in 33 short-term retrieved dual mobility liners as evidence of relative motion at the 2 bearings.

Perioperative Complications in Patients with Inflammatory Arthropathy Undergoing Total Knee Arthroplasty.

Little data exists comparing acute post-operative outcomes in patients with different types of inflammatory arthritis (IA) after undergoing a total knee arthroplasty (TKA). Our objectives were to compare perioperative complications and determine the most common complications between the different IA subtypes compared with patients with osteoarthritis undergoing primary TKA. We found significant differences when comparing complications within the different subtypes of IA.

Lack of early dislocation following total hip arthroplasty with a new dual mobility acetabular design.

Dual mobility implant designs minimise the risk of dislocation without sacrificing range of motion. Between 1st September 2008 and 31st July 2011, 5 institutions examined early clinical outcomes of a new dual mobility bearing hip system implanted in 485 primary THAs in 452 patients. Patient demographics were 46% female, a mean age of 67 years and a mean BMI of 30.

Medicaid payer status is associated with in-hospital morbidity and resource utilization following primary total joint arthroplasty.

Background: Previous reports suggest that there are major disparities in outcomes following total joint arthroplasty among patients with different payer statuses. The explanation for these differences is largely unknown and may result from confounding variables. The Affordable Care Act expansion of Medicaid coverage in 2014 makes the examination of these disparities particularly relevant.
