Prognostic value of preoperative mechanical hyperalgesia and neuropathic pain qualities for postoperative pain after total knee replacement.

Background: Total knee replacement (TKR) is the gold standard treatment for end-stage chronic osteoarthritis pain, yet many patients report chronic postoperative pain after TKR. The search for preoperative predictors for chronic postoperative pain following TKR has been studied with inconsistent findings.

Methods: This study investigates the predictive value of quantitative sensory testing (QST) and PainDETECT for postoperative pain 3, 6 and 12 months post-TKR.

Outcomes of Total Knee Arthroplasty in Patients With Rheumatoid Arthritis.

The purpose of this study was to examine current literature regarding the efficacy of total knee arthroplasty for patients with rheumatoid arthritis. Studies that assessed total knee arthroplasty outcomes in patients with rheumatoid arthritis were identified on MEDLINE from January 2009 to November 2018. All 4 studies that assessed knee pain and 9 of 11 studies that assessed knee function noted significant improvement in average knee score.

Assessment of Psychological Factors in Short-Stay Total Hip Arthroplasty Protocol.

Background: Several variables are known to correlate with the successful completion of short-stay total hip arthroplasty (THA) protocols. The role of psychological factors remains unclear. We investigated the interaction between patient-reported measures of psychological fitness and successful completion of a short-stay THA protocol.

Outcomes of Elective Total Hip Arthroplasty in Nonagenarians and Centenarians.

Background: Nonagenarians and centenarians are among the fastest growing demographics in the United States. Although consequent demand for joint replacement is projected to rise precipitously, outcomes of total hip arthroplasty (THA) have seldom been studied in this population.

Methods: A retrospective cohort of patients undergoing primary THA was established using the 2008-2017 American College of Surgeons National Quality Improvement Program.

Which Postoperative Day After Total Joint Arthroplasty Are Catastrophic Events Most Likely to Occur?

Background: Despite lacking granularity, large database registries can help provide important information on rare outcomes following total joint arthroplasty (TJA). In an era of short stay and outpatient arthroplasty, an awareness of the timeframe for most common catastrophic complications can help providers maintain an appropriate degree of suspicion for these significant events.

Methods: Patients undergoing primary TJA between 2011 and 2016 were identified in the National Surgical Quality Improvement Program and queried for 4 adverse postoperative outcomes: pulmonary embolism (PE), myocardial infarction or cardiac arrest, cerebrovascular accident, and death.

Differences in Post-Operative Outcome Between Conversion and Primary Total Hip Arthroplasty.

Background: The demand for conversion of prior hip surgery to total hip arthroplasty (conversion THA) is likely to increase as a function of increasing US hip fracture burden in addition to its application in managing other conditions. Thus, outcome analysis is warranted to better inform value-based reimbursement schemes in the era of bundled payments.

Methods: Via Current Procedural Terminology codes, the National Surgical Quality Improvement Project data files were queried for all patients who underwent primary THA and conversion of previous hip surgery to THA from 2005 to 2014.

The Lawrence D. Dorr Surgical Techniques & Technologies Award: Differences in Postoperative Outcomes Between Total Hip Arthroplasty for Fracture vs Osteoarthritis.

Background: Hip fracture is an increasingly common expanded indication for total hip arthroplasty (THA) and warrants outcome analysis so as to best inform risk assessment models, public reporting of outcome, and value-based reimbursement schemes.

Methods: The National Surgical Quality Improvement Program data file from 2011 to 2014 was used to identify all patients undergoing THA via current procedural terminology code 27130. Propensity score matching in a 1:5 fashion was used to compare 2 cohorts: THA for osteoarthritis and THA for fracture.

Risk Factors for Postoperative Urinary Tract Infections in Patients Undergoing Total Joint Arthroplasty.

. Urinary tract infections (UTIs) are the most common minor complication following total joint arthroplasty (TJA) with incidence as high as 3.26%.

The Impact of Metabolic Syndrome on 30-Day Complications Following Total Joint Arthroplasty.

Background: The arthroplasty population increasingly presents with comorbid conditions linked to elevated risk of postsurgical complications. Current quality improvement initiatives require providers to more accurately assess and manage risk presurgically. In this investigation, we assess the effect of metabolic syndrome (MetS), as well as the effect of body mass index (BMI) within MetS, on the risk of complication following hip and knee arthroplasty.

A case of extensive hyperostosis frontalis interna in an 87-year-old female human cadaver.

Hyperostosis frontalis interna (HFI) is a condition that involves thickening of the inner surface of the frontal bone with sparing of the midline. Little is known about the etiology and clinical presentation of HFI. We report unusual findings in a woman with extensive Type D hyperostosis of the frontal bone and a large hyperostotic nodule in the parietal bone with impingement on the precentral gyrus, distinguishing this from the common form of HFI.
